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.
