The FW2531 Multi-Sensor Detector is the most advanced fire detection device in the Maple Armor series, combining three critical life safety technologies into one intelligent package. By simultaneously monitoring for smoke, heat, and carbon monoxide, it provides comprehensive protection against multiple fire threats while using sophisticated algorithms to distinguish between real emergencies and nuisance conditions.
Certified to UL 268 (smoke), UL 521 (heat), and UL 2075 (CO) standards, providing comprehensive life safety compliance in a single device.
Advanced algorithms analyze data from all three sensors to provide accurate fire detection while virtually eliminating false alarms.
Automatically adjusts sensitivity and detection algorithms based on environmental conditions and sensor data patterns.
Advanced scattered light chamber for early detection of smoldering fires.
Dual-element thermal detection (fixed temp + rate-of-rise) for fast flaming fires.
Electrochemical CO sensor for life safety protection against carbon monoxide poisoning.
