HART-enabled flame detectors
The FL3100H UV/IR and FL3101H UV Flame Detectors from General Monitors are now compatible with the HART communication protocol. The Model FL3100H detects fires by monitoring in both the ultraviolet (UV) and infrared (IR) spectral ranges, making it highly immune to false alarms caused by lightning, arc welding, hot objects and other sources of radiation. The Model FL3101H monitors only the ultraviolet (UV) spectral range for optimized speed of response. Both devices feature continuous optical path monitoring (COPM), which ensures the FL3100H Series offers exceptional fire protection. The FL3100H and FL3101H operate over a broad temperature range and feature a 4-20 mA stepped output, which is the industry standard for alarm and fault indication. Each device includes three SPDT high current programmable relay outputs that provide immediate and time delayed outputs for alarm, warn and fault conditions. They also include 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. Since HART signals are carried over the same wiring as is typically used for conventional analog instruments, no rewiring is required.
The FL3100H and FL3101H detectors support oil & gas production, refining, distribution and storage operations. Other applications include chemical processing, aircraft hangars and electrostatic spray paint booths.
