FAP-440 Dual Ray Detectors

Dual Ray Technology provides better particle size differentiation resulting in fewer false alarms
Smoke threshold is adjustable and automatically compensated
Rotary switch addressing
Flexible work modes determined by the control panel
Selectable base locking mechanism prevents malicious removal of the detector
Multi-criteria or multi-sensor technology reduces false alarms
