Conduit/Cable Installation 29

5.5 Conduit/Cable Installation

The conduit and cable installation must comply with the following guidelines:

1 To avoid water condensation in the detector, it should be installed with

the conduits/cable entries facing downwards.

2 Use flexible conduits/cables for the last portion connecting to the

detector.

3 When pulling the cables through the conduits, ensure that they are not

tangled or stressed. Extend the cables about 12 inches (30cm) beyond

the Detector location to accommodate wiring after installation.

4 After the conductor cables have been pulled through the conduits,

perform a continuity test.

5.6 Detector/Source Mounting

The Detector Source should be mounted with the Tilt Mount Kit, Model

888270. The Tilt enables the Detector to be rotated up to 45º in all

directions and fine alignment of up to 3º.
