The OSI-R detector is a combined transmitter/receiver unit that can be directly connected to a conventional detector circuit. What is the detection principle of beam type smoke detectors? Select a product to view images and additional details about that model. The signal generated in the transmitter element and reflected by the prism back to the receiver element is analyzed for the presence of smoke. utilising an Infra-Red beam. Project beam smoke detectors use a beam of light to detect smoke across large areas. In normal state, IR light beams sent from transmitter reach the receiver unit. The optical beam smoke detectors designed to operate as a component of an intelligent fire alarm system. The transmitter and receiver must be mounted so that the Data Sheet (pdf) Model 6424 has been discontinued and replaced with Model Beam1224. Model# BEAM1224 The BEAM1224 is a 4-wire single ended reflected type beam smoke detector that includes an 8" reflector. Fire Detection The Protec 3000/FIREBEAM/70 is a conventional beam detector, which is compatible with the Protec 3000 range. transmitter and receiver are installed near the ceiling of the area up to 393 feet (120 m) apart, while the controller is at ground level where it remains accessible for mainte- and setup functions. The EDB01 Reflective Beam Smoke Detector is a single unit comprising a transmitter and a receiver. The FIRERAY 3000 End to End Infrared Optical Beam Smoke Detector (OBSD) has been designed using the latest optical technology, incorporating modern industrial, electronics and software techniques. Beam detectors are used in wide-open spaces instead of an array of smoke detectors. Reflective Beam Detector Smoke EC-50R/-100R comprises a transmitter and receiver in a enclosure and is usually installed between 19 inches and inches below the ceiling. The D306 Remote Indicator mounts on a standard single-gang back box. Beam detectors consist of at least one light transmitter and one receiver, which is photosensitive. Types of Beam Smoke Detector.
