Introduction
The Cerberus Pyrotronics PBA-1191 Linear Beam Detectors provide reliable monitoring over long distances that range from 17 feet to 280 feet. The PBA-1191 detector works in conjunction with a number of different reflectors, according to the requirements of the installation.
Application
The PBA-1191 Linear Beam Detector was developed to cover a wide range of applications, therefore where required, it can be used to supplement or replace pointtype smoke detectors. Some ideal applications are: large or high ceiling rooms (atriums and warehouses), aircraft hangars, churches, computer rooms, museums, malls, corridors, historical buildings, rooms with complex ceiling structures (beam construction), structures subject to frequent tremors, buildings whose walls flex as a result of temperature change or wind conditions.
Operation
The PBA-1191 Linear Beam Detector consists of a transmitter (IRLED) which emits an invisible infrared (IR) pulse through the transmitter lens. The IR pulse traverses the protected area to reach the reflector located opposite the detector and is reflected back to the detector. The detector receiver lens directs the reflected IR pulse to a silicon photodiode. The resulting electrical signal is evaluated by the detector electronics. The attenuation of the IR pulse by smoke particles viascattering and absorption, results in an alarm condition. The PBA-1191 Detector has three sensitivity settings, reduced, standard, and increased. The response threshold is set with DIP switch (S1), (S2). The Transmitter intensity (strong, weak) is to be set with DIP switch (S3).
Reflectors
The PBR-1191 Retroreflecting Prism has the shape of a pyramid whose lateral faces are formed by isosceles orthogonal triangles. Light entering through the base is completely reflected twice on the lateral faces and reflected back through the base. The base is equipped with a reflector heater. If condensation is possible, the heater should be connected to a 24V supply. Retroreflectors reflect the received light beam back along the path of incidence. The design of all the reflectors minimizes the effect of vibration and structural movement. PBR-1192 and PBR-1193 are flat reflector foils. The foils consist of microprismic elements that are formed by transparent, synthetic resin sealed to a plastic substrate.
Detector Adjustment Kit
The PBL-1191 Detector Adjustment Kit is required for proper Electrical
Adjustment and Mechanical Alignment of the PBA-1191 Linear Beam Detector.
