Marine Approved Analogue Photoelectric Smoke Sensor ALG-ENM 


  • Removable, High Performance
  • Twin fire LEDs allow 360 viewing
  • Locking mechanism (sensor to base)
  • Variable sensitivity
  • Electronically addressed
  • Pulsing/non-pulsing controlled from panel*
  • Approved by LPCB, LR & GL

Model ALG-ENM is a Marine Approved Photoelectric Smoke Sensor, which is fully
compatible with Hochiki’s ESP Analogue Addressable Protocol.

The ALG-ENM 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 ALG-ENM 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.
