Chapter 2 Switch Installation
Connecting Alarm Circuits
Note
Wire connections to the power and alarm connectors must be UL- and CSA-rated, style 1007 or 1569
twisted-pair copper appliance wiring material (AWM) wire (such as Belden part number 9318).
To wire the switch to an external alarm device, follow these steps:
Step 1
Remove the captive screws that hold the alarm connector on the switch, and remove the connector from
the switch chassis. See
Figure 2-11
.

Alarm Connector
Step 2
Measure two strands of twisted-pair wire (16-to-18 AWG) long enough to connect to the external alarm
device. Choose between setting up an external alarm input or output circuit.
Step 3
Use a wire stripper to remove the casing from both ends of each wire to 0.25 inch (6.3 mm) ± 0.02 inch
(0.5 mm). Do not strip more than 0.27 inch (6.8 mm) of insulation from the wires. Stripping more than
the recommended amount of wire can leave exposed wire from the alarm connector after installation.
Step 4
Insert the exposed wires for the external alarm device into the connections based on an alarm input or
output circuit setup (see
Table 2-3
). For example, to wire an alarm input circuit, complete the IN1 and
REF connections (See
Figure 2-12
).
