HFP Analogue Photoelectric Smoke Sensor – White Case

Model ALN-E(HFP) is a Photoelectric Smoke Sensor, which is fully compatible with Hochiki’s ESP Analogue Addressable Protocol.

The ALN-E(HFP) incorporates Hochiki’s newest High Performance Chamber Technology removing the need to use Ionisation 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-E(HFP) smoke chamber is easily removed or replaced for cleaning and utilises a unique baffle design which allows smoke to enter the chamber while keeping out ambient light.

Features and benefits:

• Removable, high performance chamber.
• Twin LEDs allow 360 degree 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 and VdS.
• SIL 2 approved variant available.
• Compatible bases - YBN-R/3, YBO-R/SCI, YBO-BS, YBO-BSB2, YBN-R/3(SCI)
