Linear Beam Smoke Detector

Beam-type smoke detectors perform smoke detection based on the attenuation principle between transmitter and receiver units that generate UV and IR beams. The UV/IR beam detector accurately evaluates alarm or fault conditions by analyzing the level of reduction or interruption of both light signals at the receiver unit. It is not affected by false alarm conditions caused by dust, insects, misalignment (up to a maximum of 2° deviation), or reflections.

The UV/IR beam-type smoke detector can operate over distances of up to 150 meters between the transmitter and receiver units.

The receiver unit is powered by a 24 VDC power supply. The transmitter module does not require an additional external power source and operates with an internal battery designed to last approximately 5 years. The battery status in the transmitter unit is continuously monitored by the main unit, and a fault signal is generated in case of low voltage.

The detector provides at least two relay outputs to transmit alarm and fault signals to the fire alarm panel. Detection sensitivity can be selected in three levels: 25%, 35%, or 50%.

The transmitter and receiver units can be installed at the same elevation or at different levels, allowing detection across varying heights.

The beam detector’s transmitter and receiver units have a minimum protection rating of IP44 against water and dust. The operating temperature range is -10°C to +55°C.
