Analogue Photoelectric Smoke Sensor (SIL2 approved)

Model ALN-EN/SIL is a Analogue Optical Smoke Sensor, which has been independently assessed and approved for use in a SIL2, low demand safety function with regards to random failure rates.

The ALN-EN/SIL 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.

The ALN-EN/SIL smoke chamber is easily removed or replaced for cleaning and utilises a unique improved baffle design which allows smoke to enter the chamber

whilst keeping out ambient light.
