standard production fastener, excluding the force required to compress the gasket, does not exceed the

minimum tensile strength specified in standards EN ISO 898-1:2013 and EN ISO 898-2:2012 or other

appropriate standards for materials not covered by these standards, when the deluge alarm valve is

pressurized to four times the nominal working pressure. The area of the application of pressure shall be

calculated as follows:

permanent distortion or rupture, an internal hydrostatic pressure of not less than twice the nominal

working pressure when tested in accordance with E.1.

4.1.1.5 The deluge alarm valve shall withstand, without leakage, permanent distortion or structural

failure, an internal hydrostatic pressure of not less than twice the nominal working pressure applied at

the upstream end with the sealing assembly closed and the pilot line pressurized to twice the supplier's

recommended pressure when tested in accordance with E.1.

EN 12259-9:2019 (E)

4.1.2.3 Deluge alarm valves, equipped with a trim in accordance with the manufacturer’s

instructions, shall not be capable of resetting after release without the need of manual intervention.

Deluge alarm valves shall be provided with a means which prevents the valve from reseating until

manually reset where:

a) the ratio of service pressure to valve outlet pressure, at the point where the tripped valve reopens

exceeds 1,16 to 1, for service pressures between the minimum service pressure and the nominal

working pressure, or
b) the installation drain is located upstream of the sealing assembly.

Deluge alarm valves having a latch for the prevention of reseating shall be tested in accordance with D.2

and E.2, without sustaining permanent distortion, cracks, delamination or other signs of failure.

Valves which are not equipped with a device which prevents the valve from reseating, and for which the

ratio of service pressure to valve outlet pressure at the point where the tripped valves reopens is

unknown or estimated, shall be tested in accordance with D.3 to determine the ratio of service pressure

to valve outlet pressure.

The supplier may provide details of the deluge alarm valve estimated ratio of service pressure to valve

outlet pressure at the point where the tripped valve reopens by submitting test evidence or

calculations.

4.1.2.4 There shall be no leakage of water when the deluge alarm valve assembly is tested in

accordance with E.2.

Valve sealing surfaces should withstand ordinary wear and tear, rough usage, compression stresses and

damage due to pipe scale or foreign matter carried by the water.

operate correctly in accordance with the supplier's performance details, without adjustment or damage,

at service pressures within the range of the minimum service pressure to the nominal working

pressure.

The supplier should provide performance details that should include the deluge alarm valve actuator

operating pressure and K-factors. Details of the pilot line height limitations above the deluge alarm

valve should be provided for wet pilot line operated deluge alarm valves.

4.1.2.6 A deluge alarm valve in the ready condition shall withstand without opening permanently a

water supply pressure failure, where the water supply pressure drops from the nominal working

pressure to 0 bar and remains at 0 bar for a period of 1 h and then rises to the nominal working

pressure at the rate of not less than 5 bar/s, when tested in accordance with E.2.3.

4.1.2.7 A pressure-loss operated deluge alarm valve shall operate before the pressure at the

actuating mechanism reaches the minimum specified by the supplier.

4.1.2.8 A deluge alarm valve operated by supply pressure shall operate when the pressure at the

actuating mechanism in the valve is:
— not more than two thirds the pressure requirements stated by the supplier and
— not more than half the supply pressure

within the range of the minimum service pressure specified by the supplier to the nominal working

pressure.

4.1.2.10 When tested in accordance with E.2.1 and E.2.2, deluge alarm valve line connections shall

conform to the following:

a) the valve shall provide a pressure of not less than 0,5 bar at the alarm port at the minimum service

pressure while actuating relevant water motor alarms and electric alarm devices;

b) the piping between the deluge alarm valve or any alarm shut-off valve, and the alarm devices shall

drain automatically after each operation.

4.1.2.11 When tested in accordance with E.2, the deluge alarm valve shall actuate associated

mechanical and electrical alarm devices.

4.1.2.12 There shall be no leakage across the sealing assembly of deluge alarm valve in the ready

condition or into the alarm port when tested in accordance with Annex G.
4.1.3 Pressure loss due to hydraulic friction loss

The supplier shall specify the pressure loss in bar at a velocity of 5 m/s, based on the nominal diameter

of the valve.

The pressure loss across the deluge alarm valve shall not be more than 0,5 bar and within ±10 % of the

supplier’s specification when tested in accordance with C.3.

The performance shall be expressed as the pressure loss in bar at a velocity of 5 m/s, based on the

nominal diameter of the valve.
4.1.4 Operational reliability of moving parts

NOTE Clearances are necessary between moving parts and between moving and stationary parts so that

corrosion or deposits of foreign matter within an assembly will not render the deluge alarm valve sluggish in

action or inoperative.
4.1.4.1 Clapper type valves shall conform with 4.1.
