Alarm connections are Form C relays and can be monitored either Normally Closed (NC) or
Normally Opened (NO). When the power is OFF, NC is closed and when the power is ON,
the NC is open.
NOTE
Relays K1 - K6 (Alarm 5 - Alarm 10) on the Alarm Relay Board are set to the
alarm position if communication with the controller (due to a malfunction or being pulled
out) is lost for more than 7 minutes. (This function is available only for Alarm Relay Board
firmware version 1.2 or later.)
NOTE
The alarm configuration will be dependent on your system configuration.
