Line type light beam smoke detector (hereinafter referred to as detector) is a reflective bus addressing type light beam smoke detector. The fire alarm and fault signals can be output through the relay and can be connected with the fire alarm controllers of different manufacturers. The detector is equipped with laser module and LED signal indication, and the whole debugging process is convenient, fast and easy to operate.
1. Reflective linear beam smoke detector with integrated design of transmission and reception;
2. Switching value signal output can be compatible with any manufacturer's signal input module;
3. Simple debugging, laser module can quickly locate the installation position of reflector, and LED indicates signal strength;
4. The automatic gain control technology is adopted, the background signal is automatically compensated, and the anti-sunlight ability is strong;
5. Built-in microprocessor, full-function self-diagnosis, automatic disturbance filtering technology;
6. Two groups of independent stepping precision fine adjustment, convenient for horizontal/vertical optical angle adjustment and accurate calibration.
The linear beam smoke detector can respond effectively to the smoke particles produced in the early stage and smoldering stage of the fire. It is mainly used to detect visible or invisible combustion products and initial fires with slow fire rate. It is applicable to large space places such as factories and warehouses that are not suitable for installing point-type smoke detectors.
1. Working temperature:-10…+55℃
2. Relative humidity:≤93%RH(40±2℃)
The detector is composed of infrared emitting part, infrared receiving part, CPU and corresponding amplification processing circuit. Under normal working condition, when there is no smoke, the infrared light emitted by the infrared emission tube can reach the receiving tube; When there is smoke, due to the scattering effect of smoke, the infrared light reaching the receiver tube will be reduced. When the infrared light decreases to the set threshold, the detector will send an alarm signal.
