Multi-Criteria Photo/Thermal/Infrared Detectors
Fire Projects recommend the FPTI-951/-IV and FPTI-951A/-IV are plug-in addressable multicriteria detectors that replace the FAPT-851 Series. They combine photoelectric, thermal, and infrared (PTIR) sensors in one unit to sense multiple components of a fire. This approach enables enhanced sensitivity to real fire with heightened immunity to nuisance particulates.
