Zeta Mains Heat Detector with 9V Battery Back-Up (LPCB Approved)

ZT-MH AC/DC heat alarms provide AC mains, DC or AC/DC powered heat detection and alarm functions within a single product. A single battery (available with some models) will ensure that the heat alarm remains operational, even if mains power is temporarily unavailable.

ZT-MH AC/DC heat alarms are suitable for general residential applications where a smoke alarm may result in unwanted activation (eg kitchens, garages with exhaust fumes, and areas subject to high levels of dust and other air-borne contaminants).

ZT-MH AC/DC heat alarms provide home owners with an easy-to-install, premium solution for property protection.
