Installing the Flame Detector
All products are provided with a flameproof and explosion-proof enclosure and have been approved
for use in Class 1 and Zone 1 environments as specified on the individual product nameplate tag.
Note: NFPA 72 and other local codes have specific requirements for flame detectors installations and must be consulted as
necessary.
Must only be installed by appropriately trained and accredited personnel.
1.
Securely mount the detector using minimum 1/4-20 or M6 sized fasteners.
Note: We recommend angling all detectors down at least 40 degrees from horizontal.
2.
Loosen, but do not remove the set screw on the cover assembly.
3.
Loosen the 3 Philips screws and remove the electro-optical Detector Module and place face
up in a safe location.
Note: Do not drop the Detector Module and do not touch the sensor array.
4.
Connect the cable gland or conduit to the detector enclosure via the ¾ '' NPT or M25
openings, as per national electrical codes for the install location. Connect the appropriate
wires rated for minimum 85ºC to the field connectors provided as per the wiring diagram on
the cover of the electro-optical detector module.
Ensure the enclosure is properly grounded in accordance with all local codes.
Use shielded cable for all communications connections and ground one end of the shield
following the product manual.
5.
Configure following this guide.
Note: Refer to the fuel and sensitivity settings table to determine the correct configuration.
6.
Connect the field connectors back onto the electro-optical Detector Module and secure the
module into the enclosure with the Philips screws.
7.
Install the cover and ensure the O-ring is compressed. Tighten the cap screw on the cover
assembly. Make a rough Field of View (FoV) adjustment by aiming the detector at the area
you want to cover.
8.
Tighten all bolts when product has been fully configured and tested accordance with the
product manual.
Note: Detector functionality and communication should be tested to confirm correct FoV and configuration in the final
system.
Do not connect test lamps to external power sources. Test lamps are battery operated only. Do not
open when explosive gases are present. Charging permitted in safe environment only.
