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 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 address to be set with decade address switches to provide exact detector locations for selective maintenance when chamber contamination reaches an unacceptable level. 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 Acclimate ™ 2251TMB photoelectric detector includes thermal detection at 135 (degree sign)F. It uses advanced on-board software to combine the signals from the photo and thermal elements to create a true multicriteria detector. It is capable of rejecting nuisance sources, but still responds quickly to real fires. The Acclimate multicriteria detector has the capability of adjusting 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 a low profile package. The 5251H model provides fixed high temperature detection at 190ºF. These thermal detectors provide cost effective, intelligent property protection in a variety of applications.
