BNC1680Multi point monitoring and alarm controller

Product Introduction

BNC1680Multi point monitoring and alarm controller, also known as controller, gas detector host, display controller, alarm host, etc., is used to detect the content of flammable gases or liquid vapors in the air within the lower explosive limit. It can be equipped with multiple detection probes and centrally control multiple points. This system uses a microprocessor as the control unit, which has high sensitivity and fast response speed. When the concentration of flammable gases in the environment reaches or exceeds the preset alarm value, the controller immediately issues an audible and visual alarm and drives exhaust or other peripheral devices to prevent explosions and fires, thereby ensuring life. This system can be widely used in factories, oil depots, liquefied gas stations, gas stations, gas stations, paint spraying rooms and other places that require fire and explosion prevention for safety detection and alarm.
