    Hochiki ALN-EN ESP Photoelectric Smoke Sensor (Ivory or White)

    The ALN-EN 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.

    Key Features

    • Removable, High Performance chamber
    • Twin LEDs allow 360° viewing - green when polling, turn red in fire
    • Locking mechanism (sensor to base)
    • Variable sensitivity
    • Electronically addressed
    • Pulsing/non-pulsing controlled from panel
    • Approved by LPCB & Vds
    • SIL Level 2 approved varients available
    • Available in white
    • 93g

    Frequently Asked Questions

    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.
