Alarm Contact Port on ACX1000 and ACX1100 Routers
The ACX1000 and ACX1100 router has four external alarm contacts (also known as potential free
contacts) for connecting the router to external alarm devices. The port labeled ALARM uses a 15-pin D-
type connector. The external alarm contact has 15 pins that accept a single core wire from external
alarm devices. A DE15 alarm cable is required to connect the ACX1000 and ACX1100 router to external
alarm devices. Use the gauge wire appropriate for the external device that you are connecting.
Whenever a system condition triggers an alarm, the alarm relay contacts are activated, which in turn
activates the external alarm devices. The alarm setting is open or closed.
You can connect and configure two output alarms and four input alarms. Two additional output alarms
are reserved and are used to indicate major and minor system alarms. Each output and input alarm has
two contacts for connecting the router to external alarm devices. Contact 1 of each alarm can be
configured as Normally Open [NO] or Normally Closed [NC] through the CLI. Contact 2 of each alarm
functions as a reference [REF] or negative potential terminal for Contact 1 of the corresponding alarm
and provides a current path for external alarm devices.
