Alarm Connector
You connect the alarm signals to the switch through the alarm connector. The switch supports one alarm
output relay.
The alarm output circuit is a relay with a normally open and a normally closed contact. The switch is configured
to detect faults that are used to energize the relay coil and change the state on both of the relay contacts:
normally open contacts close, and normally closed contacts open. The alarm output relay can be used to control
an external alarm device, such as a bell or a light. The alarm output is rated at 24Vdc/1A, 48Vdc/0.5A
maximum.
