200 Series Intelligent Low-Profile Plug-In Detectors

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.
