2151 / 2151T - System Sensor

100 Series™
Low-Profile Plug-in
Smoke Detectors
System Sensor 100 Series Plug-in Smoke Detectors offer
superb performance and reliability in a profile which is
just 2˝ (5.1 cm) deep.
Features
•Sleek, low-profile design
•Compatible with 400 Series product
•Two LEDs blink in standby, providing 360° visibility
•Broad range of adapter bases available with built-in shorting spring
•Hand-held sensitivity reader available
Model 2151 (photoelectric sensor) and model 2151T (photoelectric
sensor with thermal) can be used with a variety of 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. The sensing chamber is sealed against back
pressure air flow. The chamber top is covered by a one piece
molded screen which minimizes the entry of dirt and insects. This
screen can be removed for cleaning. 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 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.
