概述
新GA543C型可燃气体探测器采用高品质气体传感器，微处理器结合精密温度传感器能够智能补偿气敏元件的漂移，环境适应范围宽，工作稳定，无需调试，采用吸顶安装方式，安装简单接线方便，广泛用于家庭、宾馆、公寓等存在可燃气体的场所进行安全监控。可检测天然气、液化石油气，人工煤气。
探测器工作电压为直流供电。报警后可输出一对继电器无源触点信号（常开、常闭可跳线设置）, 用于控制通风换气设备或为其它设备提供常开或常闭报警触点。
当环境中可燃气体浓度达到设定阈值时, 能发出声光报警信号, 输出继电器无源触点信号。 当周围环境可燃气体浓度降到响应阈值以下时，处于报警状态的探测器将自动恢复到正常工作状态。

1. DESCRIPTION
The gas alarm is designed for single station use. Small and compact, the design and color makes it ideal for use in the
home, small commercial properties, and recreational vehicles.It is intended to detect leakage of natural gas (methane gas),
town gas, and bottled gas (propane gas). The unit is designed for DC wire-in applications. The gas alarm can be mounted
high (for methane gas) or low (for propane (LPG) gas).
It is equipped with a sturdy metal mounting bracket for quick, easy, and secure installation.
2. FEATURES
Detect all sorts of combustible gases, natural gas (methane), bottled gas (propane), LPG (Liquefied
petroleum Gas), LNG (Liquefied natural gas), coal gas, including town gas.
Easy to install, mounting bracket included. Loud 75dB alarm and LED warning light. High quality durable sensor.
Self diagnostic function by MCU intelligent
software.
Excellent reliability & High stability.
Ideal for all kitchens.
