Hochiki ACB-EW Weatherproof Addressable Multi-Heat Detector

The Hochiki ACB-EW Weatherproof Addressable Multi-Heat Detector is designed for reliable fire detection in external and harsh environments, where standard detectors are not suitable.

Featuring multi-heat sensing technology, the detector combines a variable temperature element with rate-of-rise detection, allowing it to be configured via the control panel to use either method or both simultaneously for improved fire decision accuracy.

Fully compatible with Hochiki ESP protocol systems, it provides intelligent addressable monitoring with precise device identification across the loop.

With an IP67-rated enclosure, the ACB-EW is built for outdoor use and is supplied with a dedicated base for secure installation. Flying leads allow direct connection to the loop using waterproof connectors, making installation straightforward in exposed environments.
