AGENT
DISCHARGED
– Blue
Illuminated when the pressure switch indicates the agent has been released.
For Pyrogen, feedback is from the thermal switch. If there is no pressure switch fitted, the indicator shall be
illuminated immediately the agent release signal is activated (Selected via FACP on-site programming –
refer to relevant FACP Manual) The indicator is extinguished by activating RESET on the FACP.
LOCK OFF
VALVE INHIBITED
– Yellow
Illuminated when the lock-off valve has been activated.
STAGE 2
TIMER RUNNING – Yellow Stage 2 Timer Running
Illuminated when the pre-discharge delay timer
is running.
The indicator is extinguished by activating the RESET control on the FACP.
AGENT CIRCUIT
FAULT
– Yellow
Illuminated when there is a fault on the monitored Main or Reserve
activation circuits. Eg S/C or O/C.
AGENT LOW
PRESSURE
– Yellow
Illuminated when the low pressure switch is activated. This indicates a
leakage at the agent cylinder. The low pressure switch is a separate switch.
TRIGGER ZONE
ISOLATED – Yellow
Illuminated when any of the programmed trigger zones on the FACP are
isolated.
COMMON FAULT
– Yellow
Illuminated under the following fault conditions;
¾
pressure switch monitoring fault,
¾
low pressure switch monitoring fault,
¾
lock-off valve monitoring fault,
¾
activation circuit fault,
¾
stage 1 output fault,
¾
stage 2 output fault,
¾
LCS fault (missing or extra),
¾
trigger zone(s) fault,
¾
low agent pressure and interlock fault.
INTERLOCK
– Yellow
Illuminated when the interlock input (eg from dampers, doors etc) is off
during the discharge sequence – meaning the dampers, doors etc are not closed as they should be or a
fault exists. The “Interlock” is overridden after 10 seconds and the agent is released
☞
Note: The Interlock is a Monitored Input and can be defaulted to the ON position by terminating
the input ( TB2 7 & 8 ) into a 2K2
Ω
resistor.
INITIAL AGENT
–Yellow
Illuminated when the “ Initial“ Agent is selected.
RESERVE AGENT
– Yellow
Illuminated when the “ Reserve “ Agent is selected.
Buzzer
Buzzer to sound under all fault conditions – see 5.6. Buzzer can be silenced by using the appropriate
FACP buzzer silence control.
Buzzer to sound when the LCS Inhibit control is activated – after 8 hours – treated as an isolate condition.
Buzzer also to sound when the service inhibit is activated - after 8 hours – treated as an isolate condition
