    202-004 heat alarms provide battery powered smoke and heat detection, and alarm functions within a single unit.

    Electronic thermistor sensing and microprocessor control delivers reliable performance and low maintenance.

    202-004 heat alarms are battery powered, do not require a mains supply, and are suitable for residential applications where smoke or gas detectors may cause unwanted alarms (such as cooking areas or parking garages)[WARNING – Hazardous levels of smoke and toxic gas can build up before a heat alarm might operate. Where life safety is the primary requirement in the event of a fire, smoke, gas or combination alarms usually provide earlier warning than heat alarms alone.].

    202-004 heat alarm range provides home owners and installers with an easy-to-install, economical solution for property protection applications.
