7.1 Checking FMC2000 Relay Continuity
Each relay in an FMC2000 controller has a common terminal
and a normally open (NO) and normally closed (NC) terminal.
If you think the wiring to the FA-200 Alarm Bar is correct and
that the FA-200 Alarm Bar is in working order, but that an
alarm signal is not being passed to it, check the relays in the
FMC2000 controller. Use a continuity tester or voltmeter (set to
measure resistance) to check the relay’s activity.
1. Enter the Relay Diagnostic menu. Press Enter, followed
by the password (the default is 123456).
2. Touch the probes of a continuity tester or voltmeter to
the NO and COM terminals on the relay’s relay block
inside the FMC2000.
