Smoke Detector Photoelectric Ivory

The Hochiki ALN-EN Photoelectric Smoke Detector is a high-performance, addressable smoke sensor designed for advanced fire detection. Fully compatible with Hochiki's ESP Analogue Addressable Protocol, the ALN-EN is a direct upgrade from the ALG-EN and fits the same bases. With a newly engineered high-performance chamber, it eliminates the need for ionisation sensors in most environments. Enhanced with a unique baffle design, the ALN-EN maximises smoke detection accuracy while reducing false alarms—making it ideal for commercial, industrial, and public safety systems.
