Optical Beam Smoke Detector

An optical smoke alarm also called photo electric smoke alarm works using the light scatter principle.

Optical beam smoke detector.

Generic optical beam smoke detector with transmitter and reflector. Firstly lets look at other forms of detection that are typically used and why we would choose beam detection in their place. 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. The photosensitive element of the optical beam smoke detector sees light produced by the transmitter in a normal condition.

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. Step 1 smoke enters the optical chamber. Unlike traditional detection systems reflected beam smoke detectors were designed for spacious rooms open areas and high ceilings. 16 to 328 foot protection range.

Single ended reflected type design. If smoke is present in the air then this obscures or blocks the light received by the receiver lowering the amount of light. The object includes parametric values for transmitter and reflector radius and depth beam range and coverage area. With only one device to install and align these single ended optical beam solutions saves you time and money on large area applications.

A beam smoke detector works on the principle of obscuration. 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. Their innovative features make them popular choices for spaces like warehouses atriums arenas and churches. Reflected beam smoke detectors are designed for spacious rooms open areas and high ceilings.

Optical beam smoke detectors are often installed in warehouses as a cost effective means of protecting large open spaces. With only one device to install and align these single ended optical beam solutions save you time and money on open area and high ceiling 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. The receiver is calibrated to a preset sensitivity level based on a percentage of total obscuration.

The alarm contains a pulsed infra red led which pulses a beam of light into the sensor chamber every 10 seconds to check for smoke particles. The beam detector sends out an invisible infra red ir beam of light that the receiver measures.
