Mounting
The FS24X Plus™ IR3 Flame detector is mounted to a structure which may be indoors or outdoors.
The detector is oriented to aim the detector to cover the desired area. Overlapping fields of view and
voting are recommended to deliver the required safety case.
Note: Must only be installed by appropriately trained and accredited personnel.
1.
Mount the SM4 or SM4-M bracket.
Note: Select a location with a low chance of mechanical damage and low vibration.
Ensure that the detector has a line of sight to cover the threat location. Avoid obstructions.
Avoid radiant infrared energy sources, which may cause false alarms.
Refer to the sensitivity settings. Note the inverse square law to determine range to a specific
fire type and size.
Make sure that the flame detector is weather tight before leaving in position.
Ensure only approved fittings and plugs are used to seal unused openings. Thread lock on
conduit entries may be required to ensure sealing in areas with heavy rains or chance of
flooding.
Follow all local electrical codes for glands and installation.
Ensure sufficient grease is present on the cover thread before installation. The product can
be made tamper resistant by tightening the set screw.
2.
Install the detector on the SM4/SM4-M bracket using the two bolts provided.
Note: We recommend angling all detectors down at least 40 degrees from horizontal. The SM4 and SM4-M mounts have
marked angle graduations.
Note: SM4-M is more resistant to vibration for marine or high-vibration applications.
