Fire-Lite SD365R Addressable Photoelectric Smoke Detector, Remote Test Capable, for use with DNR/DNRW, LiteSpeed Only, White (Replaces SD355R)

Optimize fire detection and maintenance workflows with the Fire-Lite Alarms by Honeywell SD365R addressable photoelectric smoke detector. Engineered for commercial and residential security and monitoring applications, the SD365R combines a modern, low-profile design with an enhanced optical chamber that reliably senses smoke from a broad range of combustion sources. The unit’s addressable capability and rotary decimal switches provide exact point identification on the two-wire SLC loop, helping first responders pinpoint incidents faster. Remote-test capable operation—activated via an external magnet—cuts inspection time and reduces disruption during routine surveillance and compliance checks. Built-in tamper resistance, an insect-resistant screen and a removable cover lower nuisance alarms and simplify field cleaning, while low standby current supports efficient, large-scale deployments. UL-listed reliability and seamless integration with Fire-Lite FACPs make the SD365R a strong choice for integrators, building managers and security professionals who need accurate fire monitoring with simplified maintenance.
