Open flame detector（JC–MH-HJ01）

1、 Function Introduction

JC-MH-HJ01 type open flame detector detects fires by detecting the ultraviolet rays generated by the combustion of substances. It is suitable for places where open flames are prone to occur during a fire. It uses a high-voltage signal of a specific amplitude and frequency to excite the ultraviolet photosensitive tube, which emits a special wavelength induction signal to accurately receive and analyze the ultraviolet rays in the flame and issue warning signals in a timely manner.

2、 Technical indicators
