Hochiki ACD-EN(WHT) Multi-Sensor with CO

The Hochiki ACD-EN(WHT) is an addressable multi-sensor detector featuring optical smoke, heat and carbon monoxide (CO) sensing technologies within a single device.

Designed for use on Hochiki ESP addressable fire alarm systems, the detector provides enhanced fire detection performance by combining multiple sensing elements. This allows the device to analyse environmental conditions more accurately and reduce unwanted alarms.

The integrated CO sensing element enables the detector to identify both fire conditions and potentially life-threatening carbon monoxide levels, allowing it to function as both a fire detector and a CO alarm where supported by the control panel.

The detector offers 24 EN-approved operating modes and programmable fire threshold levels, enabling system designers to tailor sensitivity to the environment. A two-colour LED provides clear status indication, displaying green during polling and red during alarm conditions.

With a low-profile design and a long-life CO sensor rated for up to 10 years, the ACD-EN(WHT) provides reliable multi-criteria detection for a wide range of commercial fire alarm installations.
