CHECKFIRE 210
Detection and Actuation System
TABLE 9-4: ISOLATE MODE
AMBER Isolate LED
Amber Isolate LED and Sounder pulsing quickly 2 x 30
seconds indicate CHECKFIRE 210 System is in ISOLATE
MODE.
Placing the System in Isolate Mode minimizes occurrence of
a false release during service or maintenance procedures on
the protected vehicle/equipment.
CAUTION
!
When System is in Isolate Mode, the Release Circuit cannot
be initiated by an automatic detection circuit input.
In the event of fire, manual actuation will bypass Isolate
Mode for immediate release. To operate manually:
• Press “PUSH to Activate/ Alarm When Lit” button
Or
• Pull ring pin and operate RED Strike button on an EMA or a
pneumatic manual actuator
Note: If a fault or alarm condition occurs while in Isolate
Mode the condition will be displayed and the module will
remain in Isolate Mode.
CAUTION
If an alarm condition has occurred in Isolate Mode, do not
return the System to normal until cause of detection notifica
-
tion is found and cleared. Switching the Isolate switch to the
normal position during an alarm condition results in an imme-
diate start of the Time Delay sequences leading to a release.
Amber Release, Detection 1 and 2, Power LEDs, and
Sounder pulsing quickly 1 x 1 second indicates a loss of
communication between Display Module and ICM processor.
1. Remove all power from the system, disconnect external
power and internal power if used.
2. Reconnect power; if the system still shows the four
amber LEDs, replace ICM with a new ICM.
Loss of communications can be confirmed by a review of the
Event History Log for the message: Display Fault.
