5.5 Conduit/Cable Installation
The conduit and cable installation must comply with the following
guidelines:
1 To avoid water condensation in the detector, install the Detector 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
799640. The Tilt enables the Detector to be rotated up to 45º in all
directions and fine alignment of up to 3º.
