Projected beam detector
WebSpot-Type Smoke Detectors Beam detectors are governed by UL and NFPA 72, 2013, Section A.17.7.3.7. It is important that designers understand and give full consid-eration to these requirements when selecting and applying beam smoke detectors to fire alarm systems. Coverage Beam smoke detectors can cover an area which would require a dozen An optical beam smoke detector is a device that uses a projected beam of light to detect smoke across large areas, typically as an indicator of fire. They are used to detect fires in buildings where standard point smoke detectors would either be uneconomical or restricted for use by the height of the building. Optical beam smoke detectors are often installed in warehouses as a cost-effective m…

WebNFPA 72, Section A.5.7.3.4.8, 2002 Edition, suggests that smoke beam detectors not produce an alarm condition should this occur: “Where the light path of a projected beam-type detector is abruptly interrupted or obscured, the unit should not initiate an alarm. It should give a trouble signal after verification of blockage.” WebFeb 17, 2024 · Projected beam smoke alarms are similar to photoelectric detectors in the way that they both use light phenomenons to detect smoke. This type of smoke detector is gaining popularity among people, and more and more …
WebProjected beam detectors are usually located with their beams parallel to the ceiling. However, they can be mounted vertically or at any angle to protect the area involved. … Webbeam (Figure 9), the reduction in light reaching the photosensitive device alters its output. The change in output is sensed by the detector’s circuitry, and when the threshold is crossed, an alarm is initiated. Obscuration type detectors are usually of the projected beam type where the light source spans the area to be protected.
WebThe OSI-RI is an intelligent addressable reflector-type linear optical beam smoke detector that is uniquely suited for protecting large open areas with high ceilings, where spot-type smoke detectors are difficult to install and maintain.

Webdesign is much quicker than a dual-ended projected beam detector. Alignment is easily accomplished with an optical sight and a two-digit signal strength meter incorporated into the beam detector. Listed for operation from –22°F to 131°F, the FSB-200 and FSB-200S are usable in open area applications where temperature extremes exceed the design
