Fire Sentry FS24X Flame Detectors Multi-Spectrum QuadBand Triple IR Fire and Flame Detectors firealarmresources.
Fire Sentry FS24X Detectors Features • Patented* WideBand IR™ Technology • Patented* Electronic Frequency Analysis™ • Visible Sensor for optimum false alarm rejection • Selectable detection sensitivities • Field-of-View: 110° full 100% cone-of-vision (90° full 100% cone-of-vision model also available) • Dual microprocessors for reliable performance • Real-time clock for accurate time dating of events • FirePic™ — pre-fire event data storage • Event log with date and time stamp • RS-485 ModBus communication
Fire Sentry FS24X Detectors The WideBand IR™ Infrared technology using high-speed solid-state Quantum sensors allows detection of all types of fires, hydrocarbon and non-hydrocarbon, in all weather conditions. If the detector’s signal is blocked by ordinary window glass, the patented WideBand IR sensors will still alarm to the fire but at a reduced sensitivity and slower response time. Dual microprocessors provide a high level of fail-safe operation combined with fast and reliable performance.
