Addressable Smoke & Heat Detectors

Fire-Lite's addressable detectors share one low-profile platform, and the part number tells you what each one senses. Learning that pattern makes it quick to pick the right head for a room and to match a replacement on a service call.

The SD365 is the base photoelectric smoke detector, with a factory-set 1.5 percent nominal sensitivity and two status LEDs. A T suffix adds a 135 degree Fahrenheit fixed heat sensor, so the SD365T covers smoke and heat in one head, and the SD365R supports remote testing. The AD365 is a multi-criteria detector that combines photoelectric, thermal, and infrared sensing to reject nuisance sources while still responding to real fires. For heat-only protection in kitchens, garages, and mechanical rooms, the H365 detects at 135 degrees Fahrenheit, the H365R adds rate-of-rise, and the H365HT alarms at 190 degrees for spaces that run hot. The SD365CO pairs smoke with carbon monoxide detection on ES series panels, and IV versions come in an ivory housing. The 365 series detectors ship with a 6-inch mounting base and trim ring. The D355PL duct detector housing uses an SD355R head for low-flow air handling units.
