General Instructions
If faults are indicated on the CHECKFIRE 210 Display
Module, test the connecting cables and end of circuit devices
(EMAs, EOL Device, branch terminators, PADs, etc.), for
proper connection to the system.
Before testing specific circuits, confirm completion of a
thorough visual inspection. Inspect all cables for damage
and replace if there are visible and/or mechanical signs of
damage (brittleness, deformation, discoloration, etc.). Test all
connections for loose or disassembled connectors.
Note: Remove power from system before replacing compo-
nents.
Note: Once all faults are cleared, confirm proper operation of
the entire CHECKFIRE 210 System by completing Section 6
– Operational Test and Place in Service.
If faults cannot be cleared, test each circuit and cable individ-
ually with the following procedures.
Power Circuit
If Power LED is showing no indication for more than 10
seconds check the connection of the Display Module to the
ICM as well as all power connections.
Internal Power Only: If Power LED is pulsing AMBER 1 x
10 seconds and only using internal power this indicates the
Battery Module is below an acceptable level.
• Inspect battery cable on ICM for damage
• Replace with a new/unused battery module
External / Dual Power: If Power LED is pulsing AMBER 1 x
3 seconds (dual power) or 1 x 10 seconds (external power
only), use the following steps to troubleshoot the external
power circuit.
Required Test Equipment
• New Fuse (3 amp inline ATO/ATC blade style automotive
fuse)
• Digital Multimeter
1. Disconnect Power Circuit Cable at the ICM (green
receptacle). Use the Digital Multimeter to confirm proper
voltage is available at the end of the Power Circuit Cable.
If voltage on Power Circuit Cable is correct, there is an
internal problem and the CHECKFIRE 210 ICM must be
replaced.
