HZ911 Linear Beam Smoke Detector

 1. Overview of HZ911 linear beam smoke detector

The HZ911 linear beam smoke detector is a long-range reflective linear infrared beam smoke detector. HZ911 linear light beam smoke detector is divided into two parts, the transmitter receiver and the reflector. The two parts of the detector are respectively installed on both sides of the detection space, facing each other. The transmitter emits a certain intensity infrared beam, which is received by the receiver and amplified synchronously, and then the collected signal is analyzed and judged by the built-in single-chip microcomputer. When the detector is in the normal monitoring state, the intensity of the infrared light received by the receiver is stable within a certain range; when the smoke enters the detection area, due to the scattering effect of the smoke on the light, the intensity of the infrared light received by the receiver decreases . When the smoke reaches a certain concentration and the intensity of the infrared light received by the receiver is lower than the predetermined threshold, the detector will report a fire alarm and the red working status indicator light will always be on.

HZ911 linear light beam smoke detector has a built-in single-chip microcomputer with excellent performance, which has powerful analysis and judgment capabilities. Through the calculation program solidified inside the detector, it can automatically complete the compensation for changes in external environmental parameters, fire alarm judgment and fault judgment, and The status indication is given through the indicator light and the signal output terminal.
2. Applicable places of HZ911 linear beam smoke detector

HZ911 linear light beam smoke detector adopts a new and reasonable structural design, which has strong anti-interference ability of ambient light, large protection space, easy installation and simple debugging. The detector can be used in historical buildings, warehouses, large storage areas, shopping malls, fitness centers, gymnasiums, exhibition halls, hotel lobbies, printing factories, garment factories, museums, prisons, etc., and can also be used in places with slight smoke and dust .
