205 Smoke/Heat Alarm

Keywords: Residential Smoke/Heat Alarm, 3 V Lithium Battery, Wireless Interconnect, Sounder Output

205 DC smoke/heat alarms provide battery powered smoke and heat detection, together with alarm functions within a single unit.

Advanced electronics in conjunction with a photoelectric smoke sensing chamber and sensitive heat detection element provide early detection of fire and high immunity against unwanted alarms.

205 DC smoke/heat alarms are powered by a long-life lithium-ion battery and do not require a mains supply. Models with either user-replaceable and non-replaceable batteries are available.

Interconnectable 205 DC smoke/heat alarms use a wireless transmission path. Configuration into a closed group ensures that other units within radio signal range are not affected by a test or fire alarm occurring within the configured group.
