Connecting to an External Alarm-Reporting Device

To connect the router to external alarm-reporting devices, attach wires to the relay contacts on the craft interface located to the left of the red and yellow alarm LEDs. A system condition that triggers the red alarm LED on the craft interface also activates the upper alarm relay contact, whereas a less serious alarm condition activates the yellow alarm LED and lower alarm relay contact.

The alarm relay contacts accept wire of any gauge between 28-AWG and 14-AWG (0.08 and 2.08 mm²), which is not provided. Use the gauge of wire appropriate for the external device that you are connecting.

To connect an external device to an alarm relay contact, follow this procedure (see Figure 43):

1. Prepare the required length of wire with gauge between 28-AWG and 14-AWG (0.08 and 2.08 mm²).
2. Use a 2.5-mm Phillips screwdriver to loosen the small screws on the faceplate of the appropriate alarm relay contact—the upper contact for a device that reports high priority (red) alarms, or the lower contact for the device that reports lower priority (yellow) alarms.
3. Insert wires into the appropriate slots in the front of the relay contact (NC means “normally closed,” C means “common,” and NO means “normally open”).
4. Attach the other end of the wires to the external device.

If attaching a reporting device for the other kind of alarm, repeat the procedure.
