Features & Benefits • Wide field of view offers greater fire detection coverage • Event logging stores fault and alarm history • 4-20 mA stepped output conforms to industry standard for remote alarm and fault indication • Modbus and HART user interface provides complete status and control capability in the control room • Wide operating temperature range permits use at higher ambient temperature • Continuous Optical Path Monitoring (COPM) checks optical path integrity and detector’s electronic circuitry once every minute • Three SPDT high-current programmable relay outputs provide immediate and time delayed relay outputs for alarm, warn and fault conditions

The General Monitors FL3100H and FL3101H are Ultraviolet/ Infrared and Ultraviolet-only flame detectors designed to detect unwanted fires and provide alarm outputs directly from the detector while maintaining false alarm immunity. The FL3100H detects fires by monitoring in both the ultraviolet and infrared (UV & IR) spectral ranges making it highly immune to false alarms caused by lightning, arc welding, hot objects and other sources of radiation. The FL3101H detects in only the ultraviolet (UV) spectral range for optimized speed of response. Other features of the FL3100H and FL3101H include three alarm/ fault relays, and an RS-485 serial output with Modbus RTU protocol for linking up to 128 detectors in series or 247 with repeaters. The RS-485 and HART outputs provide status, alarm, fault and other information for operation, troubleshooting or programming of the units. HART allows this feature without rewiring. The COPM (Continuous Optical Path Monitoring) self test feature checks the optical path integrity (window cleanliness) and the
