The Fire?Lite® Alarms SD365( A), SD365R(A), and SD365HT(A) intelligent plug-in smoke detectors are designed for both perfor- mance and aesthetics, and are direct replacements for the SD355 Series. A new modern, sleek, contemporary design and enhanced optical sensing chamber is engineered to sense smoke produced by a wide range of combustion sources in accordance with more strin- gent code standards. Exclusively for use with Fire?Lite's addressable fire alarm control panels, the SD365(A) Series point ID capability allows each detec- tor's address to be set with rotary, decimal address switches, provid- ing exact detector location for emergency personnel to quickly locate a fire during its early stages, potentially saving precious rescue time while also reducing property damage. Two LEDs on each sensor light to provide a local, visible sensor indication. The SD365(A) Series also offers 135°F (57°C) fixed temperature thermal sensing on the SD365T(A) and a remote test capable detec- tor on the SD365R(A) for use with DNR(A)/DNRW duct smoke detector housings.
