3. Operation

3.1 TAV set type TMX (Figures 1 and 2)

The dry pipe alarm valve set (TAV set) is an assembly module consisting of a dry pipe alarm valve set

(TAV), gate valve and various smaller fittings. It has the following functions: to separate the water supply from sprinkler pipework, which is at risk from frost . to monitor the system pressure levels for water supply and pressure in the sprinkler pipework. to release the extinguishing water in the event of a fire if one or more sprinklers have been

activated. to set off the hydraulic and electric alarms if there is a fire (alarm gong, alarm pressure switch).

The TAV set must only be installed in areas that are free from frost. Separating the frost-risk area fromthe water supply ensures that the sprinkler pipework will not freeze in the frost months.

The TAV set has been designed for a nominal pressure of PN 16. It can be supplied either in a flangedesign or with a coupling connection (only on exit side).

3.1.1 Operating conditions

The gate valve (3) in the water supply must be open, and the handwheel secured with lock andstrap. The safety device is not required in systems with electrical monitoring.

The 3/2-way cock (4) must be in the Operating position. The pressure gauge (9) gives the air pressure in the sprinkler pipework. It must be between the

maximum and minimum values shown. The pressure gauge (11) shows the water supply pressure. It must be between the maximum and

minimum values shown. The ball valve (7) in the compressed air feed must be closed; however, in systems with automatic

compressed air feed, it must be open.

In addition, for TAV sets with accelerator: The ball valve (20) in the feed pipe to the accelerator must be open, and the lever secured with a

lock. The safety device is not required in monitored systems. The ball valve (19) on the container must be closed. The pressure gauge (18) must show the same pressure as the pressure gauge (9).

3.1.2 Release

If one or more sprinklers is activated, the pressure of the compressed air in the sprinkler pipework isreduced. If the pressure falls below 1/5 of the water supply pressure, the valve head (2) opens and

water floods into the sprinkler pipework. At the same time, water flows through the alarm channel intothe alarm gong line, triggering the alarm pressure switch (12), and the alarm gong (15). The alarmpressure switch (12) sends the alarm to a permanently staffed office, such as the fire brigade.

3.1.3 Test alarm

For a test alarm the 3/2-way cock (4) is set to Test until the alarm gong is heard (15) or the electricalarm is triggered by the pressure switch (12). The pressurised water is taken directly from the water supply beneath the valve heads, while the feed pipe to the alarm channel is simultaneously closed. Thistest is meant to check the correct function of the alarm devices, and not the alarm valve.

3.1.4 Restoring operational readiness

Close gate valve (3) in the water supply.

Close the ball valve (7) if there is an automatic compressed air feed.

Empty the sprinkler pipework. Open the drainage valves on the sprinkler pipework and the ball valve(16) on the set.

In sets with accelerator, open the ball valve (19) at the container, close the ball valve (20) in thefeed pipe, and then open the vent valve (21).

Replace activated sprinklers with new ones.

Set 3/2-way cock (4) to Test.

Carry out maintenance work on the dry pipe alarm valve (see Section 4.1.4)

Close the drainage valves on the sprinkler pipework and the ball valve (16) on the set. Open the ball valve (7) in the compressed air feed and fill the sprinkler pipework with compressed air.

Note: When filling the sprinkler pipework, it is important to ensure that the 3/2-way cock (4) is set toTest, so that the alarm channel is blocked and the space below the valve head (2) andabove the drain valve (5) is ventilated.If compressed air escapes from the drain valve (5), the gasket is not perfectly sealing thevalve seat. In such an event, the 3/2-way cock can temporarily be set to Closed, untilpressure of approximately 0.5 bar has built up in the sprinkler pipework. When the 3/2-waycock is returned to the Test position, the resulting low pressure usually brings the gasketback to its normal position on the valve seat.If compressed air continues to escape from the drain valve (5), the space between thegasket and the valve seat is too great. In this case, the compressed air must be completelyreleased and the correct position of the gasket on the valve head checked (see also TAVmaintenance in 4.1.4).

Once the sprinkler pipework has been filled, the 3/2-way cock must be set to Operation. Only thenis the valve head correctly locked.

Slowly open the gate valve (3) in the water supply system.

Leak test: If water is constantly escaping from the drain valve (5), the valve head is leaking. In such acase, the gate valve (3) must be closed again, the compressed air fully released and the O-rings in the valve head (2) checked or replaced.

With a tight-fitting alarm valve, the gate valve (3) must be securely closed with a lock and strap. Thesafety device is not required in electrically monitored systems.

Note: Care should be taken to ensure that the alarm channel is always atmospherically vented viathe drain valve (5). If the alarm channel is blocked, e.g. if the 3/2-way cock is in the closedposition for a longer period, it can trigger the alarm valve.

With sets with accelerator, close the ball valve (19) at the container and the vent valve (21) in thefeed pipe. Then switch on the accelerator by opening the ball valve (20) and lock the ball valve inthe Open position with a lock (not necessary with electrically monitored systems).

Check the charge time in the instructions on the accelerator. After any unauthorised departure fromthe instructions, a maintenance check should be carried out on the accelerator (see Accelerator Maintenance 4.2.4).


16/68



3.1.5 Compressed air supply An automatic compressed air feed mechanism should normally be installed to compensate for any lossof pressure in the sprinkler pipework (e.g. a compressor unit with container and pressure reducer).

The air pressure in the sprinkler pipework must be adjusted to the water supply pressure.

The rough formula is: p Air= 1/5 p Water + 1.5 bar (safety addition)

With 10-bar water supply, this means: p Air= 10/5 +1.5 = 2.0 bar + 1.5 bar = 3.5 bar

If the pressure in the sprinkler pipework is greater, the release period for the valve increasesaccordingly.If the air pressure is too low, there is the risk of accidental release.

3.1.6 Electrical monitoring system

Electrical monitoring of the following elements in the system is required for particular risks in order toenhance the operational safety of the TAV set:

Open position for the gate valve (3) Operating position for the 3/2-way cock (4) Compressed air in the sprinkler pipework Ball valve (20) in the accelerator feed pipe.

The above-mentioned monitoring devices are only intended to report a fault to a permanently staffedoffice. The alarm pressure switch (12) is provided to alert the fire brigade.

3.1.7 TAV sets with SE2 accelerator (Figure 2)With TAV sets with no accelerator, the pressure in the sprinkler pipework must be reduced to between1/5 and 1/6 of the water supply pressure before the release point for the alarm valve is reached. With awater supply pressure of 10 bar, therefore, the pressure in the sprinkler pipework must be reduced tobetween 2.0 bar and 1.6 bar, before the alarm valve opens. The accelerator (17) is activated if thepressure falls by approximately 0.2 bar within roughly 20 seconds (this corresponds approximately to areduction in pressure in a 4 m 3 sprinkler pipework from a 3/8 sprinkler with a K factor 57) and channelsthe compressed air out of the sprinkler pipework into the alarm channel of the dry pipe alarm valve. Thevalve head (2) in the dry pipe alarm valve is opened by this surge of compressed air and water streamsinto the sprinkler pipework. The throttle (14) in the alarm gong line ensures that the compressed air isunder sufficient pressure when it is channelled into the alarm channel of the dry pipe alarm valve. Theaccelerator is generally a stipulated requirement by the VdS-CEA 4001 guideline for fire hazard classesHHP and HHS, and for pipeworks with a volume exceeding 1.5m up to a minimum of 4.0 m

3.

3.1.8 TAV sets with a SEVMX quick vent valve

If a large sprinkler pipework is already installed ( 4m) and only a short delay is required before thewater discharges from the sprinklers, the use of an quick vent valve is often an effective solution. TheMinimax quick vent valve responds when there is only a slight fall in pressure and can greatly reducethe period between the triggering of the sprinkler system and the discharge of the water. The ventingcapacity is approximately 50m of released compressed air per minute at a 2-bar operating pressure inthe sprinkler pipework. The installation of the quick vent valve should ideally be at the end of thesprinkler pipework near the test sprinkler. The design of the quick vent valve makes it unsuitable for usein frost-hazard areas. If the installation should nevertheless be required in such areas, the valve can befitted with a protective cover with built-in heating.Reference is made to Manual, item no. 84 1213 regarding planning, installation and commissioning of the SEVMX quick vent valve.

3.1.10 Maintenance of TAV sets

Inform the offices responsible about the maintenance work!

Visual checks of the general condition of the TAV set and on the fittings for correct operatingposition and for safety devices.

Check operating pressure levels on the pressure gauges.

Check zero setting of the pressure gauges by closing and opening the pressure gauge stop valve.N.B.: Effect pressure release on the pressure gauge stop valve by opening the drain plugs.

Set off the TAV set by releasing the compressed air (functional control). The gate valve (3) needs tobe suitably throttled to avoid flooding the pipework completely.

Block the water and the compressed air supply and empty the sprinkler pipework completely. Maintenance of the dry pipe alarm valve (1) in accordance with maintenance instructions in 4.1.4.

Maintenance of the accelerator (17) in accordance with maintenance instructions in 4.2.4

Check strainer (13) in the alarm gong line, and clean as required.

Recommissioning in accordance with 3.1.4 or relevant operating regulations.

Check that the charge time for the accelerator (17) corresponds to the plate information.

Check for leaks in the valve gasket on the drain valve (5).

Check the lock fittings (gate valve, ball valves, drainage valve) for leaks.N.B.: Set 3/2-way cock (4) to Operating position.

Secure the operating position of the gate valve (3) with lock and strap. The safety device is notrequired in systems with electrical monitoring.

In systems with electrical monitoring, the monitoring devices and their transmission channels mustalso be checked.

In addition with fast release dry pipe alarm valve sets TMX-S

Check the function of the solenoid valve, e.g. by activating it via the detector system.

Maintenance of the solenoid valves (22) Figure 6 if required. On this subject, see the maintenanceinstructions in 4.3.2.

3.2 TAV set type TMX-FM (Figure 3)

TAV sets with FM approval have a largely similar design to the VdS sets, so that most of the operatingmodes described in Section 3 apply here too. The differences between the FM and the VdS designs are

as follows: Under FM guidelines, the drainage (A) must be located below the valve flap. Accordingly, instead of

the normal gate valve, an intermediate flange (spool piece) is used with a drainage ball valve (A).

Following commissioning, even with a relatively well-drained pipework, there may be a back-flow of water over a longer period, which will result in water accumulating in the dry pipe alarm valve. Thiscan lead to malfunctions, especially in sets with an accelerator. Therefore an additional drainageoption is added at the outflow connection to the dry pipe alarm valve (ball valve B with vent valve).N.B.: When checking the dry pipe alarm valve for residual water, disconnect the accelerator by

opening ball valve (C) and closing ball valve (D)!

The accelerator with FM approval differs from the standard design in that it has a modified throttle

device to prevent water penetration. See also the functional description in Section 4.2.2 If shut-off fittings are used, only FM-approved tapered oval slide valves with externally rising spindle

or FM-approved shut-off gates are permissible.

3.4 Tail-end alarm valve set type MMX (Figure 5)

The tail-end valve set (DN 40) is intended for the protection of smaller areas with frost risk (volumestream design Q = 412 l/min at 5 m/s). The alarm is activated in the same way as with the standard tail-end alarm valve set via the series-connected wet pipe alarm valve set (NAV set). The water supply

pressure is max. 10 bar. Air pressure of 3.0 3.5 bar must be maintained in the dry pipework.

3.4.1 Operation

In the operating state, the diaphragm valve (1) is closed. The gasket to the water supply is in the form of a valve head with a gasket, which is held in place on the valve seat by the diaphragm chamber impinged on by the compressed air. The transfer ratio between diaphragm chamber and valve seat isapprox. 5:1; in other words, if the system is activated, the air pressure in the diaphragm chamber mustfall to roughly 1/5 of the water supply pressure. If the water supply, for example, is 10 bar, the air pressure on the diaphragm chamber must drop to approximately 2 bar for the diaphragm valve (1) toopen.The quick vent valve (3) will already open if the pressure in the sprinkler pipework falls below 2.3 bar

and this speeds up the activation of the diaphragm valve (1) through additional release of pressure. Inaddition, the quick vent valve (3) remains in the open position after activation, preventing the diaphragmvalve (1) from closing because of a renewed build-up in pressure on the diaphragm chamber. Onlywhen the ball button is pulled and when pressure has built up to more than 2.3 bar in the sprinkler pipework, the quick vent valve (3) remains locked in position, keeping the diaphragm valve (1) closed.

3.4.2 Operating state

The main locking valve (2) is open and must be secured with a lock and strap. The safety device isnot required in systems with electrical monitoring.

The pressure gauge (6) shows the current water supply pressure. It must be between the maximumand minimum values shown.

The ball valve (10) must be closed; however, in systems with automatic compressed air feed, itmust be open. The air pressure in the compressed air supply must not fall below the minimum values marked on

pressure gauges (7) and (8). The quick vent valve (3) must be kept closed and be secured with a cover against unauthorised

activation. There must be no water in the inspection glass (4).

3.4.3 Activation

The activation of one or more sprinklers produces a drop in pressure in the sprinkler pipework. If it fallsbelow 2.3 bar, the quick vent valve (3) opens, rapidly activating the diaphragm valve (1) throughadditional pressure release on the diaphragm chamber, so that water floods into the sprinkler pipework.The check valve (9) prevents the diaphragm valve (1) from closing because of the build-up in pressurein the sprinkler pipework. The open quick vent valve (3) additionally prevents a build-up in the sprinkler pipework through any leakage at the check valve (9), and any build-up in pressure from the compressedair supply. The alarm is activated via the upstream wet pipe alarm valve set.

3.4.4 Restoring the operating state

Close the ball valve (2) in the water supply and, if necessary, the ball valve (10) in the compressedair supply.

Open any drainage valves in the dry pipework and the ball valve (5) in the set (remove stopper onthe ball valve). There must be absolutely no water in the dry pipework.

The activated sprinklers must be replaced with new ones.

3.4.5 Maintenance of a tail-end valve set

Please inform the relevant offices about the maintenance work!

Visual checks of the general condition of the tail-end alarm valve set and on fittings for correctoperating position and for safety devices.

Check the zero position on the pressure gauges by closing and opening the pressure gauge stopvalves.N.B.: Release the pressure on the pressure gauge stop valve by loosening the drainage plug.

Activate the tail-end valve set by releasing the compressed air. To prevent the pipework beingtotally flooded, the main locking valve (2) should be throttled as required.

Shut off water supply and compressed air supply and fully empty the pipework.

Check inspection glass for pollution and clean or replace it as required.

Check the diaphragm valve (1) is not leaking, and if it requires maintenance. See MaintenanceInstructions in Section 4.4.2.

Check the compressed air supply, including throttle (11); if necessary, clean or replace.N.B.: When removing the throttle (11) the compressed air supply at the ball valve (10) must be

blocked off.

Recommissioning in accordance with Section 3.4.4 or the relevant Operating Regulations. Thequick vent valve (3) and the check valve (9) must be checked to ensure they are working properlyand, where necessary, replaced.

Secure the operating position of the main locking valve with lock and strap. The safety device is notrequired in systems with electrical monitoring.

In systems with electrical monitoring, the monitor devices and their transmission channels must alsobe checked.

3.4.6 Cause of faults in the tail-end valve set

3.5 Fast release dry pipe alarm valve set (TS set) type TMX/S (Figure 6)

The fast release dry pipe alarm valve set is basically a TAV set fitted with an accelerator. A solenoidvalve controlled by a detector system has been installed in addition to the accelerator.

If a fire occurs, the solenoid valve is opened by the sophisticated detection system and the compressedair is channelled from the sprinkler pipework into the alarm channel of the dry pipe alarm valve. The drypipe alarm valve opens and water floods into the sprinkler pipework, which is still filled with compressedair. If one or more of the sprinklers is activated, water is supplied to the sprinklers by a direct routerelatively quickly, without any need to release all of the compressed air in the dry pipework.If the detector system or solenoid fails, the TS set functions like a standard TAV set with accelerator.Since the TS set is used in high fire risk situations, electrical monitoring is essential.

4. Operation of key components

4.1 Dry pipe alarm valve (Figure 7)

4.1.1 Operating conditions

In the operating state, the entire valve head is locked in the valve seat, as shown in Figure 7. A gasketwhich moves freely to adjust itself to the valve seat seals the sprinkler pipework filled with compressedair. An O-ring installed radially to the system in the valve seat seals off the water supply. The spacebetween these two seals is atmospherically connected with the alarm gong line of the TAV set via thealarm channel. The locking mechanism is activated if there is an increase in pressure in the sprinkler pipework, with the valve head being pressed down and a lock holding the valve head in position. (For further details, see functional description on locking mechanism in Section 4.1.2).

The lock of the valve heads in the valve seat can only be released when the pressure in the sprinkler pipework has dropped to less than 1/5 of the water supply pressure.

air pressure : water supply = 1 : 5 to 1 : 6.5

This means that with water supply at 10 bar, the compressed air above the valve heads must drop toless than 2 bar before the dry pipe alarm valve will open. When the valve heads are forced open, notonly is the extinguishing water released, but the alarm channel is also activated to supply a hydraulicalarm gong and a pressure switch for the electric alarm signal. Following activation, the valve head isheld in the open position by a spring-loaded safety catch at the inspection port cover, so that the valvehead cannot automatically settle as a result of the build-up in the stream of water in the sprinkler pipework.


27/68



4.1.2 Locking mechanism (Figure 8)

a) Functional sequence of the valve head locking

The compressed air from the sprinkler pipework acts on the valve head (3) via the valve headsealing (4).

The valve head (3) is pushed downwards so that the guide ring (8) moves into place with the O-ring(9) in radial position in the valve seat (13).

While making this downward motion, the thrust ring (5) pushes the spring washer (6) apart. The spring washer (6) moves into position on the nut of the valve seat (13) and is held in position by

the thrust ring (5).In this state, the water supply below the valve head can now be released. The water supply pressureacts on the ring surface of the guide ring (8) and on the surface of the guide bolts (11). The pressureexerted on the ring surface of the guide ring (8) is diverted by the spring ring (6) to the valve seat (13)and has therefore no influence on the activating sequence. The only activating force is the pressure onthe relatively small area of the guide bolt (11).

Locking area


28/68



b) Functional sequence when valve head is unlockedThe activating sequence between the sprinkler pipework and water supply is in the followingrelationship:

Locking force (valve head area x p compressed air ) to activating force (piston area x p Water )

As already mentioned in Section 4.1.1, the air pressure in the sprinkler pipework must fall to below 1/5of the water supply pressure before the valve head unlocks and opens (except with TAV sets withaccelerator). The precise sequence is as follows:

Air pressure above the valve head drops to 1/5 of the water supply pressure. The water supply pressure pushes up the guide bolt (11) with the thrust ring (5) firmly attached. The spring washer (6) is pushed off by the thrust ring (5) and automatically slides inwards through

the bezel in the valve seat (13). The valve head is then unlocked.

Through the upward movement of the valve head, the gasket of the O-ring (7) is removed, admitting thewater pressure into the atmospheric alarm channel and assisting the unlocking mechanism. Onceunlocking is complete, the valve head is opened at high speed by the surge of water pressure.

4.1.3 Commissioning

The procedure for commissioning or restoring the operating state is as follows:

Risk of accident! The valve must only be opened when it is not under pressure and has beenfully emptied!

Unscrew inspection port.

Check the safety catch at the inspection port to ensure it moves smoothly and, if necessary, clean it.

Clean valve interior and valve head.

N.B.: It is generally recommended to remove the valve head, to check the gasket (4) and all theO-rings for dirt or damage and to replace parts as required. The O-rings and sliding surfaces,including the spring washer (6), must be lubricated.

Install valve head (lubricate bed) and set loosely on the valve seat. Care should be taken that thegasket rests snugly on the valve seat. If necessary, the gasket should be rotated or exchanged.

N.B.: The valve head cannot be locked by being pressed down. Instead, it locks automatically

when the sprinkler pipework fills with compressed air. Rescrew inspection port.

N.B.: The safety catch on the inspection port must be above the valve head!

Set the 3/2-way cock in the alarm gong line to "TEST" position.

Fill the sprinkler pipework with at least 3.5 bar of compressed air.

Set 3/2-way cock to "Operating".

Open the gate valve in the water supply. The set is then in operating state.

Check the operating state and the system pressure levels as described in the operating instructions.

N.B.: The air pressure in the sprinkler pipework must be adjusted to the water supply pressure(see also compressed air supply in Section 3.1.5)


29/68



4.1.4 Maintenance

a) Removing the valve head from the TAV

Risk of accident! The valve must only be opened when it is not under pressure and has beenfully emptied!

Remove inspection port. Remove the screw plugs (A) on the valve head bed. Pull out the bearing bolt (C) sideways. Remove the complete valve head.

b) Disassembling the valve headThe figure below shows the assembly requirements for the different parts.The steps for dismantling are as follows:

Loosen the stop buffer (1) and unscrew several turns. Set the valve head (3) on the points marked with an arrow. Loosen locking mechanism from valve head (3) by tapping gently with a hammer on the stop buffer (1).

N.B.: The valve head (3) with the gasket (4) sits tightly (suction effect) on the thrust ring (5). Thevalve head can also be loosened by pushing a screwdriver between the valve head (3) andthe gasket (4).

Fully unscrew the stop buffer (1). Unscrew the threaded pin (12) using a SW2 Allen key. Unscrew the guide bolt (11). Clean the separate parts. Check the gasket, O-rings and spring washer (6) for wear, and replace parts if necessary.

It is recommended to replace all gaskets (TAV-TMX gasket set).

c) Valve head assembly

Assembly is in reverse order. All of the O-rings except O-ring (9) must be lubricated.

Set O-ring (10) in the guide bolt (11).

Place O-ring (9) in the groove of the guide ring (8).

N.B.: Take care not to bend the O-ring when slipping it on. After attaching it to the groove provided onthe guide ring (8), the O-ring should be lubricated only on the outside.

Set the guide ring (8) on the guide bolt (11).

Place O-ring (7) in the groove of the guide ring (8), pulling the O-ring over the guide bolt (11).

Lay spring washer (6) on the guide ring (8).

N.B.: The inside bezel of the spring washer must be facing upwards!If an old spring washer is used, the play to the centre tappets must be checked. If there is morethan 2 mm play, the spring washer (6) must be replaced. The spring washer (6) can also be bentback manually.

Screw the thrust ring (5) onto the pre-assembled guide bolt (11).

N.B.: The O-ring (7) should not be allowed to slip off the guide bolt (11) and become pinched. The centretappets on the guide ring (8) must lock onto the grooves provided on the thrust ring (5).

If the guide bolt (11) is screwed flush with the thrust ring (5), the internal M4 thread allows thethreaded pin (12) to be screwed on.

Attach gasket (4) and valve head (3) and hand screw with max. 20 Nm the stop buffer (1), including

O-ring (2). Check the locking assembly by pressing on the guide ring (8) and unlock it again by slipping the

spring washer (6) from the thrust ring (5).

Risk of accident! When checking the locking assembly, take care not to catch your fingers!

The valve head is now fully assembled and can be installed in the dry pipe alarm valve.

d) Replacing the valve seat

The valve seat is screwed into the housing and can only be unscrewed using a special tool. The staticseal with O- rings is designed for the entire life of the alarm valve.

N.B.: There is no provision for replacement of the valve seat!

e) Further assembly information

Except for the seal area at the inspection port, all metal, sliding and sealing surfaces and the valvehead bedding should be lubricated. A waterproof, silicon-free lubricant should be used.It can be obtained in OD giving the following order details: 350-gram jar white WP300 lubricant.........................................................................Item no.: 75 2570

4.1.5 Causes of faults in TMX dry pipe alarm valve

Fault Causes

The compressed air does not lock thevalve head in the dry pipe alarm valve

Disruption in compressed air supply, e.g. pressure reducer ismalfunctioning

Water residue in valve seat, so that the valve head cannot belocked. Make sure the valve seat is ventilated (set 3/2-waycock to Test)

Spring washer (6) has been fitted the wrong way round or isbent

Wrong valve head (3). Note the marking TMX on the valvehead! Valve heads marked VMX are only meant for pre-action dry pipe alarm valves.

Compressed air escapes duringcommissioning via the drain valve

The valve head is not resting on the valve seat, but on thesafety catch

The space between the gasket (4) and valve seat is toogreat. Use a new gasket or, if need be, turn around the bentgasket!

If the build-up in pressure in the sprinkler pipework is veryslow, and even if there is very little space between the gasket(4) and valve seat (13), compressed air may still escape. Inthis case, first turn the 3/2-way cock to OFF until thepressure in the pipework has adjusted to approx. 0.5 bar.

Then turn the 3/2-way cock to OPERATING again. Theresulting pressure surge will usually push the gasket intoplace on the valve seat (13) and lock the valve head.

Constant flow or drip of water from thedrain valve

O-ring (7) or O-ring (9) is dirty or damaged.

expensive compared to the standard model and costs more for maintenance. The standard throttle istherefore installed for normal VdS purposes.4.2.3 Commissioning

The SE2 accelerator is a component in the dry pipe alarm valve set. It is connected at the SE inlet withthe sprinkler pipework and at the SE outlet with the alarm channel of the dry pipe alarm valve. Whenthe sprinkler pipework is filled with compressed air, the accelerator is activated by the opening of theball valve (11). In its operating state, the compressed air from the sprinkler pipework keeps the valvehead (3) closed. A balance is achieved via the throttle (4) or (4a) after roughly 10 minutes between thepressure in the accelerator chamber (1) and the control vessel (2). The values shown on pressuregauge (7) and on the pressure gauge for the sprinkler pipework must be the same.N.B.: With each start-up, the charge time from 1 to 2 bar in the control vessel (2) must be checked

against the pressure in the sprinkler pipework, in accordance with the test instructions on theaccelerator name plate.

4.2.4 Maintenance

The smooth functioning of the accelerator is largely dependent on the interaction between the control

vessel (2) and the throttle (4) or (4a). The accelerator is functioning properly if the pressure in thecontrol vessel builds up in the prescribed time (charge time). When testing the charge time, the testinstructions (label on accelerator) with the specified data should be followed.

After the dry pipe alarm valve has been activated, it is important to drain the pipework carefully.Residual water in the valve unit at the height of the accelerator inlet leads to malfunction. If necessary,check and drain by carefully opening the drainage valve in the dry pipe alarm valve or the vent valve(12) in the SE inlet line.N.B.: The control vessel (2) must first be vented by opening the ball valve (8)!

Risk of activating the dry pipe alarm valve! Next, recheck the SE2 charge time!

4.2.5. Causes of faults in the SE2 accelerator

Fault Causes

The accelerator charge time is tooshort

The diaphragm is leaking The throttle (4) or (4a) is missing Throttle disk or O-rings in the throttle (4) or (4a) are faulty or

missing There is water in the control vessel (2)

The charge time for the accelerator istoo long

The throttle disk and/or the filter in the throttle (4) or (4a) aredirty or blocked

The control vessel (2) is leaking, e.g. through the seal on thepressure gauge (7) or the drainage valve (8) There is water in the accelerator chamber (1) The vent valve (12) is not fully closed or is leaking

Compressed air is escaping from thedrip check valve at the TAV set

The valve head (3) is leaking; if necessary, replace the valvehead gasket

The pressure display on the pressuregauge (7) is not the same as on thepressure gauge on the dry pipework

One, or both, pressure gauges is/are faulty The ball valve (11) to the sprinkler pipework is closed The ball valve (8) is open or leaking


34/68



4.3 Solenoid valve 2/2-way

The solenoid valve for the electrical activation of the fast release dry pipe alarm valve set is a 2/2-wayvalve, with an operating voltage of 24V-DC, actuated by a detection system. In its operating state, thesolenoid valve is not actuated, i.e. in its neutral state it is closed (NC = normally closed) and thus acts

as a seal on the dry pipework. On actuation, the solenoid valve opens and the compressed air streamsinto the alarm channel of the dry pipe alarm valve.

4.3.1 Operation

The solenoid valve is not actuated in operating state, i.e. it is closed in neutral state. In this position, thetop side of the diaphragm (3) is acted upon with the pressure medium via the structural bore 0.8 mmin the throttle (4). Because of the difference in area (total area above compared to smaller ring areabelow) the diaphragm seals the valve seat securely. When the solenoid valve is activated by the coil(10) being actuated, the magnet anchor (8) releases the discharge bore 1.8 mm, so that the upper diaphragm chamber pressure is reduced. The diaphragm rises from the valve seat and the solenoidvalve switches to flow-through mode.

4.3.2 Maintenance

The controlling device in this solenoid valve is an anchor, which is acted upon by the pressure mediumand closes the discharge bore assisted by a pressure spring. The anchor chamber, therefore, isconstantly in contact with water, so that the risk of pollution is relatively high. It is therefore essential,with regard to the annual maintenance periods, to include the anchor chamber as well as the diaphragmchamber, in the maintenance operations.

The maintenance work should be carried out as follows:

Risk of accident! Maintenance work on the valve should only be carried out when it is not under pressure and has been fully emptied!

Turn off power supply to solenoid (detection system) Loosen mounting nut (11) (SW 14 spanner) and pull the coil from the tube body Loosen tube body (7) (SW 22 wrench size) and unscrew from the cover (2). Clean tube body (7),

anchor (8) and pressure spring (9) and check if they are damaged or need to be replaced.

N.B.: Only replace tube body, anchor and pressure spring (7, 8, 9) as a set. Screw in the complete tube body again and tighten by hand (metallic seal). Unscrew cover (2) (SW 4 Allen key) Remove diaphragm (3), clean it and check if it is damaged or needs to be replaced. Clean throttle, sieve and O-ring (4, 5, 6) and check if they are damaged or need to be replaced.

N.B.: The sieve must be perfectly clean. If there are lime deposits, the sieve should be replaced Reinsert the diaphragm and throttle with the O-ring in the valve housing and screw on the valve

cover.

N.B.: The correct position for the diaphragm and throttle is crucial for operation. If the throttle or O-ringis missing, the solenoid valve will malfunction.

Reattach the coil and screw tight.

Reconnect the power supply to the solenoid valve.Important note: Carry out a final check on the proper operation of the solenoid valve using the

detection system or a test detector.

4.4 Diaphragm valve DN40-MMX (Figure12)

The diaphragm valve DN40-MMX is intended for use in the tail-end valve set to release extinguishingwater after the sprinkler system has been activated.

4.4.1 Operation

In operating state, the compressed air in the diaphragm chamber keeps the valve head closed againstthe force of the water pressure. When the pressure in the diaphragm chamber falls to roughly 1/6 of thewater supply pressure, the valve head opens, releasing the flow of extinguishing water. In operatingconditions, an adequate supply of compressed air to the diaphragm chamber must be ensured (with anautomatic compressed air supply and, if necessary, electronic monitoring).

4.4.2 MaintenanceBefore any maintenance work, the ball valves for the water supply and automatic compressed air feedmust be closed on the inlet side and the complete sprinkler pipework vented. Further maintenance stepsare as follows:

Risk of accident! Maintenance work on the valve should only be carried out when it is not under pressure and has been fully emptied!

Loosen and remove compressed air supply, including the pressure gauge at the screw fittings.

Loosen and unscrew the complete control section at point X - X.

Unscrew cover (12) on the diaphragm valve.

Clean diaphragm (1) and valve head (3) and check if they are damaged or need to be replaced.

Check the smooth movement of the valve head lead, and clean and lubricate as required.

Lubricate moving surfaces, O-rings and sealings.

Assemble control section and screw it into the valve housing again. Reconnect the compressed air supply and the restart the tail-end valve set in accordance with the

operating instructions.
