Connecting The Acx1000 Or Acx1100 Router To External Clocking Devices - Juniper ACX1000 Hardware Manual

The terminal blocks that plug into the alarm relay contacts are supplied with the router. They accept
wire of any gauge between 20 AWG and 14 AWG (0.52 and 2.08 mm
gauge of wire 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 8 AWG and 14 AWG (0.08 and 2.08 mm
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to
one of the ESD points on the chassis.
3. 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.
4. 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").
5. 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.
6. 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.
