200 Series

Intelligent Low-Profile

Plug-In Detectors

The System Sensor 200 Series intelligent plug-in

smoke detectors with integral communication provide

point location for alarm communication and selective

maintenance.

Features

• Sleek, low-profile design

• Analog communications

• Low standby current

• Rotary address switches

• Superior EMI protection

• Dual LEDs for 360° visibility

200 Series smoke detectors are intelligent (addressable) detectors

with point ID capability that enable each detector address to be set

with decade address switches to provide exact detector locations.

The sensitivity of 200 Series detectors can be programmed using the

control panel software to suit the environment. In addition, detector

sensitivity is continually monitored and reported to the panel.

The System Sensor 2251B photoelectric detector’s unique

optical sensing chamber is engineered to sense smoke produced by

a wide range of combustion sources. Dual electronic thermistors add

135°F fixed temperature thermal sensing on the 2251TB model.

The 2251BR is a remote test capable detector for use with DNR(W)

duct smoke detectors.

thermal detection at 135°F. It uses advanced onboard software to

combine the signals from the photo and thermal elements to create

a true multi-criteria detector capable of rejecting nuisance sources,

but still responding quickly to real fires. Separate photo and thermal

elements also allow the Acclimate detector to provide different

responses to smoke or heat. In addition, the Acclimate detector can

adjust its sensitivity according to its environment.

The 1251B ionization detector incorporates a unique single-source,

dual-chamber design to respond quickly and dependably to a broad

range of fires.

Both the 5251B and 5251RB detectors use an innovative

thermistor sensing circuit to produce 135°F fixed and rate-of-rise

thermal detection in low-profile packages. The 5251H model

provides fixed high-temperature detection at 190°F. These thermal

detectors provide cost-effective, intelligent property protection in a

variety of applications.
