The field circuit is monitored for open line faults and ground faults and the contact must be wired with an end-of-line resistor. The type of input contact is configurable for NO/NC operation.
Alarm Events: An module input will produce an ALARM event when an alarm generating contact device is activated. The device LED will indicate the alarm condition by red steady on.
Supervisory/Trouble/Monitor Events: The FW811 input module can be configured to be a supervisory, trouble or monitor signal which will produce an event when a signal input appears on its associated contact. The device LED will indicate the event condition by red steady on.
