    Connecting the M40e Router to an External Alarm-Reporting Device

    To connect the router to external alarm-reporting devices, attach wires to the RED ALARM and YELLOW ALARM relay contacts on the CIP. A system condition that triggers the red or yellow alarm LED on the craft interface also activates the corresponding alarm relay contact.

    The terminal blocks that plug into the alarm relay contacts are supplied with the router. They accept wire of any gauge between 24-AWG and 12-AWG (0.20 and 3.33 mm2), which is not provided. Use the wire gauge appropriate for the external device you are connecting.

    To connect an external device to an alarm relay contact:

    1. Prepare the required length of wire with gauge between 24-AWG and 12-AWG (0.20 and 3.33 mm2).
    2. While the terminal block is not plugged into the relay contact, use a 2.5-mm flat-blade screwdriver to loosen the small screws on its side. With the small screws on its side facing left, insert wires into the slots in the front of the block based on the wiring for the external device. Tighten the screws to secure the wire.
    3. Orient the terminal block according to the labels to the left of the appropriate relay contact (NC means “normally closed, C means “common,” and NO means “normally open”).
    4. Plug the terminal block into the relay contact and use a 2.5-mm flat-blade screwdriver to tighten the screws on the face of the block.
    5. 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.
