The Hochiki ALG-EN Photoelectric Smoke Detector is fully compatible with Hochiki's ESP Analogue Addressable Protocol. The Hochiki ALG-EN no longer needs to use Ionisation Smoke Sensors in the majority of applications because of the newest High Performance Chamber Technology.
This technology allows the sensor threshold level to be reduced. This also improves the signal to noise ratio of the ALG-EN, reducing susceptibility to false alarms. The ALG-EN smoke chamber is easily removed or replaced for cleaning and utilizes a unique improved baffle design which allows smoke to enter the chamber while keeping out of ambient light.
