Wiring
Wire in accordance with applicable requirements of the latest
editions of the local codes and standards and the local
authority having jurisdiction.
Note:
When stripping wire ends, exposing more wire may
cause a ground fault or circuit malfunction on unsupervised
wiring; exposing less wire may result in a faulty connection.
Strip 1/4 in. (about 6 mm) from the ends of all
wires that
connect to the terminal block of the module.
Notes
•
Refer to the Signature loop controller installation sheet for
SLC wiring specifications.
•
Each terminal on the module is limited to a single
conductor.
To wire the module:
1. Verify that all field wiring is free of opens, shorts, and
ground faults.
2. Make all wiring connections as shown in Figure 2.

Typical application
Figure 3 shows a typical application. Here, each detector
operates its sounder base. The SIGA-CRR is used to activate
all
sounders, according to system programming rules. The CR
control relay is optional, and is used to disable or silence the
sounders.
