Honeywell Analytics / Vulcain FS24X-911-21-1 QuadBand Triple IR Detector with 3/4" NPT Conduit Entries, 90° Field of View, 4-20 mA Output, FireBusII, Aluminum Enclosure

Protect critical infrastructure with the Honeywell Analytics / Vulcain QuadBand FS24X-911-21-1 triple IR flame detector — engineered for fast, dependable flame detection in hazardous industrial environments. This flame detector combines QuadBand IR sensing and a solar‑blind 90° cone‑of‑vision to reliably detect hydrocarbon fires at ranges greater than 200' to a 1' heptane source while reducing false alarms from sunlight and hot surfaces. Built for integration into modern safety and security systems, the unit offers a non‑isolated 4‑20 mA output plus FireBusII and RS‑485 Modbus communications for real‑time monitoring, event logging and centralized surveillance of fire safety status.

Designed with a rugged copper‑free aluminum enclosure and dual microprocessors, the Vulcain FS24X delivers continuous self‑testing, automatic optical path checks and accurate time‑stamped diagnostics that simplify maintenance and keep uptime high. Certified for hazardous areas (FM/cFM, IECEx, ATEX), it’s ideal for oil & gas, chemical plants, and other critical security and monitoring applications. Specify the FS24X to strengthen your fire detection strategy and improve response — contact us to discuss installation or order units for your site.
