Connecting Alarm Circuits
After the device is installed, you are ready to connect the DC power and alarm connections.
Wiring the External Alarms
The device has two alarm input and one alarm output relay circuits for external alarms. The alarm input
circuits are designed to sense if the alarm input is open or closed relative to the alarm input reference
pin. Each alarm input can be configured as an open or closed contact. The alarm output relay circuit has
a normally open and a normally closed contact.
Alarm signals are connected to the device through the six-pin alarm connector. Three connections are
dedicated to the two alarm input circuits: alarm input 1, alarm input 2, and a reference ground. An alarm
input and the reference ground wiring connection are required to complete a single alarm input circuit.
The three remaining connections are for the alarm output circuit: a normally open output, a normally
closed output, and a common signal. An alarm output and the common wiring connection are required
to complete a single alarm output circuit.
The alarm connectors are on the device panel and are detailed in
