The following figure shows the completed wiring for two external alarm
devices. The first alarm device circuit is wired as an alarm relay input
circuit—the IN1 and REF connections complete the circuit. The second
alarm device circuit is wired as an alarm relay output circuit by using the
normally open side of the form C relay contacts. The NO and COM
connections complete the circuit.
