How do projected beam detectors work

WebDec 10, 2014 · They work by having an emitter side that sends out a beam of human-invisible IR light, then a receiver across the way which is sensitive to that same light. When something passes between the two, and its not transparent to IR, then the 'beam is broken' and the receiver will let you know. http://www.avalon.cz/inc/getfile.php?file=58bf0a72b067e2a0d5bd692ded7d7bf5f4c272b3

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. Location Asia Pacific Australia - English China - Chinese India - English WebThis would involve identifying either (a.) a generic set of design fires (i.e. range of combustibles, range of fire-growth rates, etc.) through which detector performance can be assessed, or (b.) developing a time by which smoke detectors need to respond to provide a tenable environment for occupants.

WebUsing reflective technology, beam-detecting systems comprise two parts which need to be installed on opposite sides of the building, directly facing each other. On one side you will have a reflective panel, and on the other, the optical beam head which emits the light, and then analyses the light received back from the reflector. In normal ... WebIn this mode, an object is detected when the light beam is blocked from getting to the receiver from the transmitter. A retroreflective arrangement places the transmitter and … 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. ips rally challenge

This mode uses two separate housings, … WebIn this mode, an object is detected when the light beam is blocked from getting to the receiver from the transmitter. A retroreflective arrangement places the transmitter and receiver at the same location and uses a reflector to bounce the inverted light beam back from the transmitter to the receiver.

WebThe beam is transmitted towards a specially designed reflector mounted at the far end of the area to be protected, and the receiver monitors the attenuation of the returned signal. … WebSystem Sensor BEAM1224S consists of a transmitter/receiver unit and a reflector. When smoke enters the area between the unit and the reflector, the smoke causes a reduction in the signal. When the smoke level reaches the predetermined threshold, an alarm is activate.
