Description
1. Product Title
Fireye 95DSS3‑1WOC‑ InSight II Dual UV‑IR Integrated Flame Scanner
2. Product Overview
The 95DSS3‑1WOC is a SIL‑3 capable dual‑spectrum integrated flame scanner from Fireye InSight‑II series for burner‑management safety systems. It incorporates both ultraviolet and infrared sensors to simultaneously capture flame radiation signatures, delivering robust flame discrimination and greatly reducing nuisance trips caused by background hot‑surface radiation. 95DSS3‑1WOC features internal terminal‑block wiring (no quick‑disconnect cable connectors), dual flame relays, fault relay, dual 4‑20 mA analog outputs for flame‑strength indication, auto‑configuration, and multiple configurable flame‑flicker frequency filters. The rugged NEMA 4X / IP66 aluminum housing fits hazardous‑area furnace‑mount installations. It provides validated flame‑present / flame‑loss status to burner control logic, triggers safety shutdown upon unexpected flame‑out, and prevents unburnt‑fuel accumulation and furnace explosion hazards for boilers, process heaters and industrial furnaces.
