Beam detectors are used primarily for detecting smoke in large open spaces where traditional point detectors would be impractical. They work by projecting a beam of infrared or ultraviolet light across an area to a receiver. Any smoke that enters the path of the beam will scatter or obscure the light, triggering an alarm.
Applications of Beam detectors to cover large areas, reducing the number of detectors needed.
Can be mounted at different heights, making them versatile for various applications.
Must have a clear line of sight between the transmitter and receiver.
Regular maintenance is needed to ensure the beam path remains unobstructed.
Duct detectors are installed within HVAC (Heating, Ventilation, and Air Conditioning) systems to detect smoke in the air ducts. They are crucial for early detection of smoke in HVAC systems to prevent the spread of smoke throughout a building. The application of Duct detector are in commercial buildings, hospitals, hotels, and any structure with a central HVAC system.
Essential in preventing smoke from spreading through ventilation systems.
