Description

With a unique optical sensing chamber designed to sense smoke particles produced by a wide range of combustion sources, OT**1 series optical smoke detectors are well suited to effectively respond to a wide spectrum of fires including slow smoldering fires, often generated in households. The detectors are loaded with extra features and are available in a wide range of models. Features 1) Advanced photoelectric smoke sensing technology 2) Sleek ergonomic design 3) Very loud alarm horn 4) Test button for verify battery status and alarm operation 5) Low-battery warning 6) Mounting bracket and screws 7) Easy install, move and maintain. 8) Meet UL**7 standard Options 1) OT**1: basic 2) OT**1A: AC**0/**0/**0V 3) OT**1B: Battery backup 4) OT**1R: Relay output 5) OT**1I: Interconnection function allows for up to *0 additional units. If one of the detectors senses smoke, all of the interconnected detectors will also alarm hazardous situation.
