CHECKFIRE 210
Detection and Actuation System
Release Circuit
If Release LED is pulsing AMBER indicating a release circuit
fault and cannot be cleared check release circuit cable.
Required Test Equipment (Confirm test equipment is new
and functioning properly)
• 2 - Release Circuit Terminators (Part No. 439436)
• Release Circuit Test Plug(s) (Part No. 440912) – one
for each PAD
1. Power down system.
2. Replace all PADs with Release Circuit Test Plugs.
3. Power up system.
4. If fault clears, there is at least one faulty PAD. Repeat
above steps (1- 3) for each PAD except at step 2 replace
1 Release Circuit Test Plug with a PAD one at a time to
determine the faulty PAD.
5. If fault does not clear, disconnect Release Circuit Cable
at the blue ICM release receptacle. Install Release
Circuit Terminator directly to the receptacle on the ICM.
If Release LED continues pulsing AMBER, there is an
internal problem and the CHECKFIRE 210 ICM must be
replaced.
CAUTION
!
When handling the PAD, always point actuating end
away from yourself and others. On electrical initiation,
PAD operates very quickly and a small brass disk force
-
fully separates from actuating end. Physical injury may
occur from contact with the actuating pin and/or the
detaching disk.
1. POWER DOWN
2. REPLACE ALL PADS WITH
TEST PLUGS
3. POWER UP
4. IF FAULT CLEARS, CHECK
FOR FAULTY PAD.
