Connecting the TX Matrix Plus Router to External Alarm-Reporting Devices

To connect an external device to an alarm relay contact for each TXP-CIP (see Figure 1):

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.

   Caution: During the initial installation before the chassis is grounded, you must connect to an approved site ESD point. See the instructions for your site.

2. Prepare the required length of wire with gauge between 28-AWG and 14-AWG (0.08 and 2.08 mm²).
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. Connect the major and minor alarm circuits to the NO (normally open) pins on the alarm connectors. Tighten the screws to secure the wire.

   Note: The top, middle, and bottom slots correspond to NC (normally closed), , C (common), and NO (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.
