DANGER
RISK OF IMPROPER FLAME DETECTION
l Installation, Commissioning, Periodic Testing, Calibration, and all other Maintenance must be
performed only by trained professionals.
l Install in accordance with all local codes.
l Follow all warnings, cautions, and instructions.
l The suitability of the system installed is the responsibility of that system’s designer and
installer.
l Routinely check the system for proper operation and/or damage.
l Replace damaged and/or non-operating devices.
WARNING
RISK OF IMPROPER FLAME DETECTION
l Install only in areas in accordance with the environmental and hazardous area ratings.
l Carefully review mounting area and position in accordance with the FS24X Plus™ FM
Performance Appendix and this Manual to ensure optimal flame detection regarding the
angle of device and unobstructed view.
l Avoid potential sources of direct or indirect radiation in the flame detector field of view.
l Do not touch the sensors on the front of the electronics module.
l Avoid direct sunlight into the flame detector window – use provided sunshade, aim flame
detectors down at 40 degrees or more when possible, and use multiple detectors to cover
hazardous areas from different directions.
l Avoid close proximity to rapid modulation/chopping of sunlight (creating moving dark
shadows) as optical sensor performance can be reduced, e.g. close trees in the wind, rotating
blades.
