5.3.3 Environmental Factors
• Observe the ambient temperature range for the specific model – refer to 8.2.4 Environmental Specifications.
○ For outdoor installations or other areas exposed to intense, direct solar radiation, the detector may reach
temperatures above specifications.
▪ For this condition, a cover for shade may be required to bring the detector temperature within
specifications. As with any cover or object nearby, ensure the field of view of the detector is not
obstructed.
• Avoid conditions of ice build up on the optical detector windows. Complete icing-over of the optical detector window
can result in fault conditions.
• Modulated reflected sunlight shining at the face of the FL5000 reduces flame detection distance.
5.4 Detector Mounting and Installation
The FL5000 is enclosed in an explosion proof assembly, which is rated for use in the environments specified in Addendum
A - Standards and Compliance Certifications.
• The unit should be mounted free from shock and vibration and convenient for visual inspection and cleaning.
• The detector(s) should be tilted downward so that dust or moisture does not accumulate on the sapphire window.
• The detector(s) should be mounted in locations, that prevent people or objects from obscuring the detector’s FOV.
• The mounting clamp must be torqued to 50 ft-lbs.
Frequent inspection, cleaning, and sensitivity checking is suggested for detectors mounted in dirty environments.
Conduit seal must be within 18” of unit.
Non-hardening thread sealant should be used if the plugs are removed or re-installed in order to preserve ingress
protection rating.
NOTICE
The FL5000 conduit entry should be sealed per the Canadian Electrical Code Handbook (Part 1, Section 18-154) and NEC
Article 501. Conduit seals or approved Ex d glands prevent water or gas from entering the detector’s housing through the
conduit entry. Water entering the housing through the conduit entry will damage the electronics and nullify the warranty.
