This alarm port supplied on a 25 pin D-type connector provides six relay contact clo-
sures to indicate the status of the alarms. Each relay provides three contacts where the
“com” pin is the switch toggling between normally open (n.o.) and normally closed (n.c.).
The summary alarm is indicated by an LED on the front panel – this also acts as a pow-
er fail alarm with contacts 22 and 24 being open whenever power is removed from the
unit.
