Beam detector

Reflected Beam Smoke Detection. With only one device to install and align, these single-ended optical beam solutions saves you time and money on large area applications. 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.

Detection with optical smoke detector can be slow in these places. Because smoke has to reach the detector mounted to the ceiling. However beam type smoke detectors are recommended for places with ceilings higher than meters.

These devices are typically installed in large areas where spot type smoke detection is not practical due to cost or location. By using advanced dual wavelength projected beams and optical imaging. How does beam detectors work? What is a beam smoke detector?

Infrared beam detectors overcome the inherent problem of reflective IR detectors —that is, the problem of ambient light interfering with the detection. They do this by separating the photo-diode and photo-transistor into separate enclosures. Single Infrared Beam Sensor, Waterproof Photoelectric Detector Active IR Alarm Host for Security and Anti-Jamming-Half Egg Shaped $14.

The OSID range of open-area smoke detectors deliver a great package for reliable smoke detection in large or open spaces. With the use of CMOS imaging technology OSID not only provides reliable smoke detection but has been designed for rapid installation and reliable operation during the life time of the detector. The OSI-RI-SS is a single-ende reflected type beam smoke detector that includes an reflector and an integral sensitivity test. This prevents a single beam detector in trouble from disabling other initiating devices on the same loop.

The reflected infrared light is detected by the receiver and analyzed. Smoke in the beam path will reduce the received infrared light proportionally to the density of the smoke. The detector analyzes this attenuation or obscuration of light and acts accordingly. Mount securely to solid structural surfaces Position beam as high as possible, but with a minimum distance of 0.

Beam smoke detectors , which come with a transceiver and a receiver, have an advantage over spot smoke detectors because you can mount them on a wall or below the level of spot detectors on the ceiling. Beam detectors also sense when smoke builds up over a distance. The OSI-RI-SK is a intelligent addressable reflector-type linear optical beam smoke detector. It is uniquely suited for protecting large open areas with high ceilings, where spot-type smoke detectors are difficult to install and maintain.

The D2(VDC) and D2(VDC) Long‑range beam smoke detectors have a separate transmitter and receiver. The signal is reflected by a prism and analysed for smoke presence. The Notifier FSB-2and FSB-200S are intelligent, addressable reflected beam smoke detectors for protecting open areas with high and sloping ceilings, and wide-open areas, where spot-type smoke detectors are difficult to install and maintain. Source like IR LE LASER, or any type.

Detector like Photodiode etc. Beam Detectors Working Principle: A Beam Detector has two main parts. We offer a wide range of laser beam position detectors for optical alignment including Quadrant Cell Photoreceivers, PSDs, and Thermopile Position Sensors.

Please see our Beam Position Sensor Guide for more information. The built-in laser provides rapid initial alignment and the detector head will then automatically. APPROVED ACCESSORIES The following accessories can be purchased separately for use with this beam detector. BEAMLRK The BEAMLRK allows reflected beam detectors to be installed at separations between 2and 3feet (to 1meters). At these distances, four 8˝ × 8˝ reflectors must be used to provide enough reflected.

Up to detector heads can report to a single ground level controller. In addition,each system controller houses two pairs of fire and trouble relays,one per detector. Once the detector head is installeusing the easyfit mounting system an integral LASER can be activated. The wide angle of the IR beam allows for an easy adjustment and for a reliable long-term stability.
