Intelligent Detectors

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. The ALN-EN 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.

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 variants available
• Available in white

Model ATJ-EN is a Multi-Heat Sensor, which is fully compatible with Hochiki’s ESP Analogue Addressable Protocol.

The ATJ-EN incorporates a Variable Temperature heat element and a Rate of Rise heat element, both of which are controlled from the Control Panel, allowing either thermal element or both elements simultaneously to be active in making the fire decision. The sensor polling LEDs can also be controlled via the Control Panel (pulsing/non-pulsing)

Model ACC-EN is a Multi-Sensor, which is fully compatible with Hochiki’s ESP Analogue Addressable Protocol, and incorporates a thermal element and High Performance photoelectric smoke chamber. The ACC-EN has three modes, which are controlled from the Control Panel, allowing either the optical element or thermal element or both elements to be active in making the fire decision. The sensor polling LEDs can be controlled via the Control Panel (pulsing/non-pulsing). The ACC-EN smoke chamber can easily be removed or replaced for easy maintenance.

Model ACB-EW is a Waterproof Multi-Heat Sensor, which is fully compatible with Hochiki’s ESP Analogue Addressable Protocol. The ACB-EW incorporates a variable Fixed Temperature heat element and a Rate Of Rise heat element, both of which are controlled from the Control Panel, allowing either thermal element or both elements simultaneously to be active in making the fire decision. The sensor polling LEDs can also be controlled via the Control Panel (pulsing/non-pulsing). Rated to IP67, the unit can be used externally and is supplied with its own fixing base which is used to fix the sensor. Flying leads from the sensor connect directly to the loop via waterproof connectors.
