S12 sprinkler test
Alarm Retarding Devices - ANS -An alarm check valve that is exposed to changing water supply pressure needs an alarm
retarding device. This is required to prevent false alarms when the check valve clapper is lifted from its seat by a
temporary pressure surge. Vane type water flow switches sensitivity can also be adjusted to changing water pressures.
\blue disk - ANS -partially out of service- on all fire department connections
\Booster pumps/special service pumps - ANS -Booster pumps are sometimes used in sprinkler systems. They small
pumps with limited power are usually located in the basement or taking suction from gravity tanks. The booster pump is
used when the water pressure available at the highest sprinkler head does not quite meet the needs of the sprinkler
system. This small pump increases the water pressure in the sprinkler system until it reaches acceptable levels. The
booster pump should not be confused with the fire pump or the jockey pump.
\Curb Valves - ANS -Gate valves of the non-indicating type are provided in water distribution systems. Gate valves allow
the sprinkler system to be shut off for repairs or maintenance. Such valves are normally a non-rising stem type. They are
operated using a special key wrench. A valve box is located over the valve to keep dirt from the valve. The valve box also
provides a convenient access point for the valve wrench to the valve nut. A complete record should be made for each
valve in the system. This record should include the exact location, the date it was installed, the make, the direction of
opening, number of turns to open, and any maintenance that was performed.
The control valve for the building may also be on the outside wall or attached to an upright post, known as a post indicator
valve (PIV). The building or section of the building controlled by the valve is usually marked on the post. The position of
this valve (open or closed) is shown through a telltale opening in the post. On some posts, a padlock must first be opened
to release the operating wrench or wheel handle.
\deluge sprinkler system - ANS -employing open sprinklers that are attached to a piping system that is connected to a
water supply through a valve that is opened by the operation of a detection system installed in the same areas as the
sprinklers. WHEN IT OPENS, water flows into the piping system and discharges from all sprinklers attached.
\DELUGE SPRINKLER SYSTEMS - ANS -equipped with open sprinkler heads designed to wet down an entire area
involved in a fire. This system is needed when there is danger of a fire rapidly spreading throughout the building. The
, deluge system will slow down the spread of the fire. Deluge systems are suitable for hazardous occupancies. This
includes buildings in which flammable liquids or other hazardous materials are handled or stored.
The sprinkler heads in the deluge system are open at all times. Under normal conditions there is no water in the piping.
The air in the piping is not under pressure. A closed control valve prevents water from flowing into the system. A fire
detection device automatically opens the control valve when a fire is identified. A supervisory device signals when the
valve is opened. When the valve is opened water flows into the system. The water is then discharged out all of the
sprinkler heads. The water control valve may also be opened manually.
\deluge valve - ANS -water supply control valve intended to be operated by actuation of an automatic detection system
that is installed in the same area as the discharge devices. INTENDED USE IS MANUAL AND AUTO

sprinklers system water supply and can be powered by electric, diesel or steam. connected to public water source or tank.

\Fire Pumps - ANS -used as a main water supply source for sprinkler systems. They may also be used in combination
with gravity tanks to supply sprinkler system. Fire pumps are designed to take the water from a supply source and then
discharge the water into the fire protection system under pressure. The amount of pressure with which the water is
discharged from the pump is called the total head. The total head is measured in pounds per square inch (psi). The higher
the psi rating of the pump the greater the

2. system air a nd water pressrue recorded.
3. relieve pressure by opening inspector test valve (use stopwatch)
