Product Overview

Linear Beam Detectors (Model PBA-1191) from

Siemens Industry

─ Fire Safety provide reliable

monitoring over long distances that range from 17 to

280 feet (5M

− 100M for Canada.) Model PBA-1191

works in conjunction with various types of reflectors,

according to each reflector’s installation

requirements.

Application

Model PBA-1191 was developed to cover a wide

range of applications. Hence, Model PBA-1191 can

be used to supplement or replace point-type smoke

detectors, when required. Some examples of the

aforementioned applications include:

 large or high ceiling rooms (atriums and warehouses)

 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

 aircraft hangars

 churches

 computer rooms

 museums

 malls

 corridors

 historical buildings

Model PBA-1191 should not be used in applications

where the beam is interrupted on a repeatable basis.

Operation

Model PBA-1191 consists of a transmitter (IRLED) that

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 then reflected back to the detector.

Operation ─ (continued) The receiver lens of the detector 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, via scattering and absorption, results in an alarm condition. Model PBA-1191 has three (3) sensitivity settings: Reduced Standard Increased Flat Reflector (Models PBR-1192 and PBR-1193) The response threshold is set with DIP switches: S1 and S2.
