Connecting the PTX5000 to an External Alarm-Reporting Device

To connect an external device to an alarm relay contact on the craft interface:
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 mm
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.
