Replace Alarm Relay Wire

The alarm relay contacts located on the craft interface to the left of the red and yellow alarm LEDS connect to external alarm devices that report conditions that trigger a red or yellow alarm (see Figure 88). The alarm relay contacts accept wire of any gauge between 28-AWG and 14-AWG (0.09 and 2.09  mm²), which is not provided. Use the gauge of wire appropriate for the external device that you are connecting to the relay contact.

To replace the wires connecting to an alarm-reporting device, follow this procedure:

1. Prepare the required lengths of replacement wire with gauge between 28-AWG and 14-AWG (0.09 and 2.09  mm²).
2. Disconnect the existing wires at the external device.
3. 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.
4. Remove existing wires from the alarm relay contact and insert replacement wires (the NC label on one contact means "normally closed," C means "common," and NO means "normally open"). Tighten the screws to secure the wire.
5. Attach the other end of the replacement wires to the external device.
