Conventional End to End Beam Optical Beam Detector

Operation

The system comprises a modern looking Transmitter head, which emits a narrow beam of infra-red light to an associated Receiver head, with a compact Low Level Controller. Once smoke crosses through and thus obscures the IR beam path, the signal strength at the Receiver drops below a preset level which in turn results in an alarm condition. Both the detector heads, Transmitter and Receiver, have integrated alignment thumbwheels for ease of alignment. Using these thumbwheels provides a smooth and repeatable alignment process. The detector heads have up to 10 degrees of adjustment in both planes. For further adjustment, a bespoke Adjustment Bracket (29600-931) is available, which offers up to 180 degrees movement in both planes, as well as a full 360-degree rotation. The Conventional End-to-End Optical Beam Detector has been designed so that it can be installed by one operator, with its laser assisted alignment method combined with easy to use alignment LED’s offering a visual feedback. Integrated laser alignment aid can be activated at the Controller or at the Receiver head. An optional feature is to power the Transmitter from he Controller by wiring directly, thus reducing the number of power supplies required. The low level Controller incorporates a LCD display, which offers a full icon-based, easy-to-use interface unit. This Controller enables ease of commissioning, testing and maintenance of the beam detection system. During commissioning the detector sensitivity and fire thresholds can be selected, along with the user variable time to fire and time to fault settings. The system is fully compliant with the requirements of RoHS and WEEE.

Product Information

The Conventional End-to-End Optical Beam Detector has been designed using the latest optical technology, incorporating modern industrial, electronic and software techniques. This detector offers cost effective protection of large, open area spaces with high ceilings. It is also very suited to applications where access to ceiling mounted smoke detectors presents practical difficulties. The Conventional End-to-End Optical Beam Detector is ideal for applications where line of sight for the IR (infra-red) detection path is narrow and where the building structure uses reflective surfaces. It has also been designed to be aesthetically pleasing and thus can equally suit modern architectural buildings as well as heritage sites, particularly where ornate ceilings exist.
