FireNex

A multi-criteria fire detector is an intelligent fire detection device that combines multiple sensing technologies—typically photoelectric smoke detection and thermal heat sensing—to provide faster, more accurate fire alerts while minimizing false alarms. Unlike conventional single-sensor detectors, multi-criteria detectors analyze multiple environmental parameters simultaneously. By evaluating both smoke particles and temperature rise, they confirm real fire conditions before triggering an alarm, making them ideal for high-risk and mission-critical environments.
