PROJECT MANUAL
Version: January 2012
i. The activation of any standpipe or sprinkler valve tamper switch shall activate the system
supervisory service audible signal and illuminate the LED at the control panel and the remote
annunciator. Differentiation between valve tamper activation and opens and/or grounds on
fire alarm initiation circuit wiring shall be provided.
j. A combination waterflow indicator/sprinkler supervisory switch combination IDC type shall be
selected allowing a single pair of wires to monitor both conditions. Waterflow monitor shall
have priority over sprinkler supervisory monitoring.
k. Activating the Supervisory Service Acknowledge Switch shall silence the supervisory audible
signal while maintaining the Supervisory Service LED on indication that the tamper contact is
still in the off-normal state.
l. Restoring the valve to the normal position shall cause the Supervisory Service LED to
extinguish, indicating restoration to normal.
m. A manual evacuation means shall be provided to activate the system NACs.
n. Alarm and trouble conditions shall be immediately displayed on the control panel front
alphanumeric display. If more alarms or troubles are in the system, the operator shall be able
to manually scroll to display new alarms. The first 10 fire alarm zones in alarm shall be
displayed simultaneously in chronological order.
o. The system shall have an alarm list means that shall allow the operator to display all alarms,
troubles, and supervisory service conditions with the time of occurrence. This shall allow for
the determination of the most recent alarm and may also indicate the path that the fire is
taking.
p. The control panel shall be capable of supplying 4 Amps @ 24 VDC power output for external
system use including power for NACs.
q. An additional internally mounted power supply rated at 5 Amps @ 24 VDC shall be provided.
as required to service initiating circuits.
19. SUPERVISION
a. The system shall contain the number of independently supervised initiation circuits shown on
the drawing plus a minimum of two spare circuits so that a fault in any one zone shall not
affect any other zone. The alarm activation of any initiation circuit shall not prevent the
subsequent alarm operation of any other initiation circuit.
b. There shall be sprinkler supervisory initiation device circuits for connection of all sprinkler
valve tamper switches to perform the Supervisory Service Operation. This independent
initiation circuit shall be labeled Supervisory Service and shall differentiate between tamper
switch activation and wiring faults.
c. There shall be sufficient (number as required) independently supervised and independently
fused NACs for audible notification appliances horns, and visible notification appliances.
Disarrangement conditions of any circuit shall not affect the operation of other circuits.
d. Each independently supervised circuit shall include a discrete panel readout to indicate
disarrangement conditions per circuit.
e. The incoming power to the system shall be supervised so that any power failure must be
audibly and visibly indicated at the control panel and the remote annunciator. A green "power
on" LED shall be displayed continuously while incoming power is present.
f. The system batteries shall be supervised so that a low battery condition or disconnection of
the battery shall be audibly and visibly indicated at the control panel and the remote
annunciator.
g. Additional monitoring shall be provided to initiate a depleted battery warning at the panel
when battery operation has exceeded the battery capacity.
h. The System Expansion Modules shall be electrically supervised for module placement.
Should a module become disconnected from the controls, the system trouble indicator must
illuminate and audible trouble signal must sound.
i. The system shall have provisions for disabling and enabling all circuits individually for
maintenance or testing purposes. Restoration of a disabled circuit displays the status of the
circuit and initiates a count down timer allowing the operator to “Abort the Enable” to prevent
unwanted activation of notification appliances, off-premise reporting, and emergency controls.
