Connecting Alarm Circuits
After the device is installed, you are ready to connect the DC power and alarm connections.
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
