Dust Cover 2251 with B210LP (A) suffix denotes ULC listed product Product Overview Sleek, low-profile design Analog communications Low standby current Rotary address switches Superior EMI protection System Sensor 200 Series intelligent plug-in smoke detectors with integral communication provide features that surpass conventional detectors. Detector sensitivity can be programmed in the control panel software. Sensitivity is continuously monitored and reported to the panel. Point ID capability allows each detector’s address to be set with decade address switches, providing exact detector locations for selective maintenance when chamber contamination reaches an unacceptable level. Model 2251 photoelectric detector’s unique optical sensing chamber is designed with superior signal to noise ratio. It’s engineered to sense smoke produced by a wide range of combustion sources. Dual electronic thermistors add 135°F fixed temperature thermal sensing on the 2251T. Model 2251TM is a photoelectric smoke detector with supplementary 135°F thermal. Also known as Acclimate™, it uses advanced on-board software to combine the signals from the photo and thermal elements, creating a true multicriteria detector capable of rejecting nuisance sources, but still responding quickly to real fires. Acclimate has the capability of adjusting its sensitivity according to the type of environment that it is installed in. Model 1251 ionization detector incorporates a unique single source, dual chamber design to respond quickly and dependably to a broad range of fires. ® Models 5251P and 5251RP offer 135°F fixed and rate-of-rise thermal detection in a low profile package. These thermal detectors provide cost effective, intelligent property protection in a variety of applications.
