HONEYWELL FS24X-911-10-5 Fire Sentry FS24X Multi-spectrum Triple IR Flame Detector

Overview The Honeywell FS24X-911-10-5 is a Fire Sentry FS24X multi-spectrum triple IR (IR/IR/IR + Visible) flame detector. It adopts patented WideBand IR quantum sensor technology, detects hydrocarbon and non‑hydrocarbon flames, and supports 4‑20mA and RS485 Modbus output, widely stocked as spare for oil & gas, chemical and power plant fire safety systems.

Features This FS24X detector uses dual microprocessor algorithm to suppress false alarms. The FS24X-911-10-5 supports FirePic™ pre-event data recording, built-in optical self-test, relay outputs for alarm/fault feedback. It is rated IP66 / NEMA 4X, with hazardous area certification for Zone 1/2 installation.

Specs Model: FS24X-911-10-5 Series: Fire Sentry FS24X Type: Multi-spectrum triple IR flame detector FOV: 90° standard Communication: 4‑20mA, RS485 Modbus Housing: Copper-free aluminum Protection class: IP66 / NEMA4X Certifications: CE, ATEX, FM, SIL2 Product status: fire safety spare

Principle The detector samples multi-band infrared and visible light signals, judges flame characteristics by built-in algorithm. It converts flame alarm signal into 4‑20mA / Modbus data and triggers dry contact relay alarm. It stores event logs and FirePic data for post-incident analysis.

Applications The FS24X-911-10-5 is widely used in refineries, offshore platforms, LNG plants, turbine enclosures and chemical skids. It is used for early flame detection and fire protection for hazardous industrial areas.
