Hochiki ESP Addressable Smoke Detector
Summary
The ALN-EN is a Photoelectric Smoke Sensor designed to enhance safety through advanced technology. Fully compatible with Hochiki’s ESP Analogue Addressable Protocol, this sensor incorporates the latest High Performance Chamber Technology. This innovation eliminates the need for Ionisation Smoke Sensors in most applications, allowing for increased sensor threshold levels, improved signal-to-noise ratio, and reduced susceptibility to false alarms. The smoke chamber is easily removable for cleaning and features a unique baffle design that permits smoke entry while blocking ambient light.
Features
- Removable, high performance chamber
- Twin LEDs allow 360° viewing
- Locking mechanism (sensor to base)
- Variable sensitivity
- Electronically addressed
- Pulsing/non-pulsing controlled from panel
FAQ
When replacing an existing ALG-E optical smoke with this ALN-EN, will my system need to be re-programmed?
It depends if the panel in question doesn’t support the new device type then the panel will not need any programming and the new device will be seen with the old product code.
However if the panel supports the new device types, then you will get a wrong device type when they are sapped over, depending on panel type this will just need an auto learn of the loop to correct.
