Automatic Ball Drip - answer An automatic drain valve horizontally installed at the low
point in the piping between the lower check valve and the Fire Department connection
of automatic sprinkler systems. Water pressure from a Fire Department pumper
automatically closes this valve. It automatically re-opens when pressure ceases,
permitting this piping to drain and thereby preventing freezing.
4 types of sprinkler heads - answer1.) pendent
2.) upright
3.) sidewall
4.) concealed
Pendent sprinkler heads - answerDesigned to be installed in such a way that the water
stream is directed downward against the deflector. Hangs from above ceiling pipes and
distributes water in a domed or conical pattern using a convex deflector. This is the
most common head for sprinkler systems
Upright sprinkler heads - answerSprays water upward to a concave deflector, producing
a dome-shaped spray pattern. Install deflector-up to cover specific areas and prevent
ice and debris from collecting in the head. Used where obstructions interfere with
coverage and in dry pipe systems facing freezing temps
Sidewall sprinkler heads - answerInstalled along walls or beneath beams where ceiling
piping is unavailable. Most are used for areas tight on space (small rooms, closets,
hallways). Sprays in a half-circle pattern
Concealed sprinkler heads - answerConcealed sprinkler heads are installed in walls or
ceilings and are fully covered with a fire sprinkler cover plate. Heat sensitive plate
detached at temps roughly 20 degrees lower than the fire sprinkler head
The Fire Department connection or connections for a sprinkler system must be pressure
tested every ___ years by a __________ - answerMust be tested once every 5 years by
a Master Fire Suppression Piping Contractor, with a fire department representative
present
Impairment coordinator shall maintain all maintenance records for a minimum of ____
years - answer3 years
What are the glass bulb sizes for sprinkler heads? - answer3mm for quick response
sprinklers and 5mm for standard response sprinklers
, Fire pump - answerA pump that is a provider of liquid flow and pressure dedicated to
fire protection. A fire pump is a part of a fire standpipe 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 and volume to the standpipe
system risers and hose standpipes.
Fire pump, automatic standpipe - answerA fire pump located at or below street level that
supplies the lower 300 feet of a standpipe system or a combined standpipe and
sprinkler system.
Fire pump, limited service - answerA fire pump with a motor rating not exceeding 30 hp
and utilizing a limited service fire pump controller.
Fire pump, special service - answerA fire pump that is located above street level and
that receives its water supply from a gravity tank or suction tank supplying water to fire
sprinkler system and/or Fire Department hose outlets
Acronym SIN stands for... - answerSprinkler Identification Number. Sprinklers
manufactured after Jan. 1, 2000 are required to be marked to identify performance
characteristics.
Deluge Sprinkler System - answerSprinkler heads are always open. There is no water in
the piping until a fire detection device trips and opens the control valve. Needed when
there is a danger of a fire rapidly spreading through the building. Suitable for hazardous
occupancies
Maximum number of sprinkler heads that can be shut off on a wet system with
permission from FD - answer10 heads to avoid freezing. Only with permission from local
FD
Dry Pipe Sprinkler System - answerInstalled where it is impractical to install a wet pipe
system due to freezing temps. Pipes are kept under air/nitrogen pressure. When a head
opens, the air pressure is released, enabling the water pressure to push open the dry
clapper valve to flow into the pipes and out of the head(s).
What is water hammer - answerA condition where a sudden increase in water pressure
may cause the valve to trip. Air pressure in dry systems is usually kept 15 to 20psi
above normal valve trip point to prevent water hammer from tripping the valve
unnecessarily.
What are 2 quick opening devices used on dry pipe sprinkler systems to reduce the
delay between a sprinkler opening and the discharge of water? - answerAccelerator and
exhauster. They both automatically activate when a drop of 2psi in air pressure is
detected in the pipes

of automatic sprinkler systems. Water pressure from a Fire Department pumper
