Installing cables

When installing cables for the flame detector, consider the following:
• Ensure all cables to the detector are well shielded in order to comply with EMC
requirements (see
• The end user must use suitable rated blanking plugs for all unused entries.
• Ground the detector to the nearest ground point (not more than 9.8 ft. (3 m) from the
flame detector).
• Install the detector with the cable entries and conduit pointed downwards.
2.5.1 Installing conduit
The conduit used for the cabling must comply with the following:
• To avoid water condensation in the detector, install the detector with the conduits that
include drain holes pointed downwards.
• When using the optional tilt mount, use flexible conduits for the last portion
connecting to the detector.
• For installation in atmospheres as defined in group B of the National Fire Protection
Agency (NFPA) 72E, seal the conduit inlets.
• When pulling the cables through the conduits, ensure that they are not tangled or
stressed. Extend the cables about 12 in. (30 cm) beyond the detector location to
accommodate wiring after installation.
• After pulling the conductor cables through the conduits, perform a continuity test.
