21 13 16 - 3
July 2017
Fire Suppression
GUIDE SPECIFICATION
Los Angeles World Airports
1.
The integrated releasing control panel sequence of operation shall be factory
programmed to perform the following:
a.
The activation of the electric detection AND the opening of an automatic
sprinkler is necessary to cause the deluge valve actuation.
b.
The activation of the electric detection alone will not cause water to enter
the system piping.
c.
The opening of an automatic sprinkler OR damage to system piping
without the detection condition satisfied will activate the "very low air"
alarm pressure switch but water will not enter the system piping.
d.
Activation of the electric detection AND the "very low air" alarm
pressure switch will activate the solenoid valve open, causing the deluge
valve to open and allowing water to enter the system piping. The alarm
pressure switch will activate. Water will flow out of any open sprinklers
and/or any openings on the system.
e.
Operation of the emergency manual release will depressurize the priming
chamber, causing the deluge valve to open and allowing water to enter
the system piping. The alarm pressure switch will activate, Water will
flow out of any open sprinklers and/or any openings on the system.
f.
When AC Power and DC power supplied by the backup batteries is lost,
the system shall “fail-safe” and function as a dry pipe system. The
normally open solenoid will remain open, and the pneumatic actuator is
the only device holding the priming water in the priming chamber. When
a sprinkler operates, air pressure is lost and the pneumatic actuator
opens. Priming water is drained from the priming chamber, causing the
deluge valve to open and allowing water to enter the system piping. The
alarm pressure switch will activate. Water will flow out of any open
sprinklers and/or any openings on the system.
g.
Trouble condition on detection zones, or "very low air" alarm zone, or
the normally closed solenoid output will disable the normally open
solenoid and the pneumatic actuator is the only device holding the
priming water in the priming chamber. When a sprinkler operates, air
pressure is lost and the pneumatic actuator opens. Priming water is
drained from the priming chamber, causing the deluge valve to open and
allowing water to enter the system piping. The alarm pressure switch will
activate. Water will flow out of any open sprinklers and/or any openings
on the system.
J.
Air Supply: The automatic sprinkler piping is supervised by air from a compressed air
source installed inside the pre-action riser room. The air supply must be regulated and of
the proper size in order to be able to restore normal system air pressure within 30
minutes.
K.
Detection & Signaling System: Supply and install a complete electrical detection system
including all conduit, wiring, smoke detectors, signaling devices, control panel and
connections to auxiliary functions. A bell or a horn shall be installed near the riser room.
L.
Provide necessary relays for fire alarm interface.
