Agent Release / LCS Indicators
There are 12 indicators on both the Agent Release Module and Local Control Station. They are;
MANUAL
ACTIVATION
(Red) Illuminated when a manual release sequence has commenced. A Manual
release sequence can only be started by activating the manual release at the FACP or LCS.
The indicator is extinguished by activating RESET on the FACP.
MANUAL
ACTIVATION
( Red) Illuminated when a manual release sequence has commenced. This occurs
when the selected zone(s) on the FACP have gone into alarm. For dual zones, the indicator should
flash when the first zone goes into alarm, and steady when the second zone goes into alarm.
Indicator is extinguished by activating RESET on the FACP.
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) 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 e.g. 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;
➢
pressure switch monitoring fault,
➢
low pressure switch monitoring fault,
➢
lock-off valve monitoring fault,
➢
activation circuit fault,
➢
stage 1 output fault,
➢
stage 2 output fault,
➢
LCS fault (missing or extra),
➢
trigger zone(s) fault,
➢
low agent pressure and interlock fault.
INTERLOCK
(Yellow) Illuminated when the interlock input (e.g. 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

resistor.
INITIAL AGENT
(Yellow)
Illuminated when the “Initial Agent” is selected.
