ANSWER-1
------ is A sprinkler system employing automatic sprinklers that are attached to a piping
system containing air or nitrogen under pressure. The release of the air or nitrogen,(as
from the opening of a sprinkler) results in the water pressure opening a valve known as
a dry pipe valve, resulting in the flow of water into the piping system and out of the
fused sprinklers heads. - ANSWER-DRY PIPE SPRINKLER SYSTEM
----A pump that is a provider of liquid flow and pressure dedicated to fire protection. A
fire pump is a part of a fire sprinkler system's water supply and can be powered by
electric, diesel or steam. The pump intake is either connected to the public underground
water supply piping or a static water source (e.g., tank, reservoir, lake). The pump
provides water flow at higher pressure to the sprinkler system risers and hose
standpipes. - ANSWER-FIRE PUMP
----are designed to control a fire until its original fuel source is depleted or until fire-
fighting activities can commence. A fire is controlled by cooling the ceiling-level air
temperatures, reducing the fire's rate of heat release and pre-wetting adjacent
combustibles. - ANSWER-CONTROL MODE SPECIFIC APPLICATION SPRINKLERS
(CMSA)
----are likely to make automatic sprinklers inoperative or slow down the speed of
operation. They can also seriously block the spray nozzles in the sprinkler heads. They
can damage, weaken or destroy the delicate parts of the sprinkler heads. - ANSWER-
corosive vapors
----is a condition where a
sudden increase in pressure may cause the valve to
trip. - ANSWER-Water Hammer
----is A deficiency that does not have an effect on the performance of the fire protection
system, but correction is needed for the proper inspection, testing, and maintenance of
the system(s) - ANSWER-NON CRITICAL DEFICIENCY
,----is an indicating type of control valve used for fire sprinkler system. - ANSWER-OS &
Y valv
----loaded sprinkler heads with new sprinkler heads rather than attempting to clean
them. If the deposits are hard, attempts to clean the heads are likely to damage them.
This damage may prevent the sprinkler heads from working properly. The damage may
also cause the sprinkler head to leak. - ANSWER-Replace
----pumps supply the water to most gravity tanks - ANSWER-Automatic fill
----Switches have a paddle inserted inside the main supply piping perpendicular to the
direction of flow. Upon waterflow, the paddle switch transmits an alarm. - ANSWER-
Vane type waterflow -
----systems are designed for situations where there is danger of serious water
damage. - ANSWER-Preaction
---,---,--- and other debris may cause damage to the pump or obstruct the sprinkler
system piping - ANSWER-mud, gravel and leaves
. Sprinkler system supervision is commonly provided for several purposes. They are
used to - ANSWER-1) water supply control valves, 2) low water level in water supply
tanks, 3) low temperature in water supply tanks or ground level reservoirs, 4) high or
low water level in pressure tanks, 5) high or low air pressure in pressure tanks, 6) high
or low air pressure in dry pipe or pre-action sprinkler systems, 7) failure of electric
power supply or phase reversal to fire pumps and, 8) automatic operation of electric fire
pumps.
