205 Smoke Alarm

Keywords: Residential Smoke Alarm, 3 V Lithium Battery, Wireless Interconnect

205 DC smoke alarms provide battery powered smoke detection and alarm functions within a single unit.
Advanced electronics in conjunction with a photoelectric smoke sensing chamber provide early detection of fire and high immunity against unwanted alarms.
Interconnectable 205 DC smoke alarms use a wireless transmission path. Configuration into a group ensures that other units within radio signal range are not affected by a test or fire alarm occurring within the configured group.
205 DC smoke alarms are powered by a long-life lithium-ion battery and do not require a mains supply.
The 205 DC smoke alarm is suitable for general residential applications, and provides home owners and installers with an
easy-to-install, long-life solution for life safety and property protection applications .
