VFD/S-LA880 optical section smoke detector linear beam infrared beam

 1. Overview of VFD/S-LA880 optical section smoke detector

Linear beam smoke detector (also known as optical cross-section smoke detector, divided into visualization and standard type, this model is the standard type) is an intelligent smoke detector, which uses optical cross-section image smoke detection Detection technology, consisting of transmitters and receivers, each receiver can correspond to multiple transmitters (the number of transmitters is determined according to the site conditions), can implement arbitrary curved surface coverage for the protected space, and has the ability to distinguish emission light sources and interference light sources Ability. It is composed of an image acquisition unit, an embedded intelligent fire analysis platform, etc., and realizes functions such as video acquisition, fire analysis, fire alarm, fault alarm, and video encoding transmission. Communication with the monitoring center through optical fiber Ethernet realizes intelligent analysis, distributed detection, networked transmission and centralized management. It is suitable for special places with large spaces such as tobacco warehouses, railway stations, and exhibition centers.
