ALN-ASN Hochiki Analogue Photo Optical Smoke Detector White
Please login to see your pricing   


ALN-ASN is a Optical Smoke Sensor, which is fully compatible with Hochiki's ESP Analogue
Addressable Protocol. The ALN-ASN 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-ASN 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.
Compatible bases: YBN-R/3(WHT), YBO-BS(WHT), YBO-R/SCI(WHIT), YBO-BSB(WHT) and
the recess adaptor YBN-UA(WHT)
