Honeywell FS24XP-SMGXX FS24X Triple IR Flame Detector, Stainless Steel, M26

The Honeywell FS24X Plus FS24XP-SMGXX is a multi-spectrum triple infrared (3IR) flame detector for hazardous areas. Based on Honeywell's WideBand IR technology, it responds quickly to the radiant energy of flaming fires and keeps working in rain, mist, fog and smoke.

This version has a polished 316 stainless steel enclosure with two M25 conduit entries and is supplied as a kit with a mount and sunshade. It communicates status through relays, a 4-20 mA output, RS-485 Modbus and HART, and is approved to EN 54-10.
