Connect to an External Alarm-Reporting Device

You can connect the router to external alarm-reporting devices through the relay contacts on the craft interface next to the LEDs labeled RED ALARM and YELLOW ALARM (see Figure 47). A system condition that triggers the red or yellow alarm LED on the craft interface also activates the corresponding alarm relay contact.

The alarm relay contacts accept wire of any gauge between 28-AWG and 14-AWG (0.09 and 2.09 mm²) wire, which is not provided. Use the gauge of wire appropriate for the external device that you are connecting to the contacts.

To connect an external device to an alarm relay contact, follow this procedure:

1. Prepare the required length of wire with gauge between 28-AWG and 14-AWG (0.09 and 2.09 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.

To attach a reporting device for the other kind of alarm, repeat Steps 1 through 4.
