ALN-EN(SCI) is a Photoelectric Smoke Sensor with SCI, which is fully compatible with Hochiki’s ESP Analogue Addressable Protocol.

ALN-EN(SCI) incorporates Hochiki’s newest High-Performance Chamber Technology removing the need to use Ionisation Smoke Sensors in the majority of

applications. This also allows the sensor threshold level to be increased, thereby improving the signal-to-noise ratio and reducing susceptibility to false alarms.

ALN-EN(SCI) smoke chamber is easily removed or replaced for cleaning and utilizes a unique improved baffle design that allows smoke to enter the chamber

whilst keeping out ambient light.
