Air Sampling-Type Detector (BK734)

BK Air Sampling Detector is an air suction smoke detector capable of collecting air sample through the air sampling pipe network and carrying out detection and early warning at the very early stage. The detector adopts the detection mode of active sampling, the advanced laser detection technology and the system application software with powerful functions. The detector consists of an air pump, a filter, a laser cavity, a control circuit and a display circuit, wherein the air pump continuously collects air samples from the protective zone through the sampling pipe network consisting of PVC pipes or steel pipes and sends the air samples into the laser cavity, the density of the smoke is obtained in the laser cavity through the laser scattering caused by the smoke, and then the software algorithm with artificial intelligence will judge the level of the alarm and finally output the alarm signal. Thanks to the advanced laser technology and artificial intelligence technology, the detector has very high sensitivity and false alarm protective capability. The built-in microprocessing software of the detector provides wide user-defined parameters and logical control functions for our users. The detection is not only easy to be connected with other fire alarm and fighting systems, but also easy to be integrated in the building management system. The detector, which adopts a standard modularized structure, is provided with a standard LCD display and programming module. The module capable of the operating status of the detectors and various alarm information has three flexible mounting modes: 1. Self installation of the detectors, 2 installation near the detection field, 3 long-distance installation in the control center. A plurality of detectors can form a short-distance or long-distance network containing maximally 128 detectors to realize centralized network management. The detector, which adopts four sampling pipes with a protective area reaching 2, 000 m2, is capable of detecting the status of the air current in the pipes and the fire alarm status at real time. The technology has applied for state patent and has filled up a gap at home.
