100 Series Low-Profile Plug-In Smoke Detectors
100 Series Plug-in Smoke Detectors offer superb performance
and reliability in a profile which is just 2” (5.1 cm) deep. Model
2151 (photoelectric sensor) and model 2151T (photoelectric
sensor with thermal) can be used with a variety of different
adapter bases in several wiring configurations and voltages.
Other features include: low current draw, stable performance in
high air velocities, built-in tamper resistant base design,
remote LED option, removable cover, and built-in test switch.
The 100 Series is designed to meet the performance criteria
designated by UL. Its sensing chambers are sealed against
back pressure air flow, dirt, and insects. This chamber is protected by a fine mesh screen which can be cleaned or
replaced. Additional key features include a variety of mounting
bases and a full line of accessories.
All 100 Series photoelectric smoke detectors contain a unique
optical sensing chamber designed to sense smoke particles
produced by a wide range of combustion sources. A custom
integrated circuit incorporates signal processing to reduce
false alarms.
Model 2151(A) photoelectric detector’s unique optical sensing
chamber is engineered to sense smoke by a wide range of
combustion sources. Dual electronic thermistors add 135°F
fixed temperature thermal sensing on model 2151T.
