可燃气泄露探测报警器

概述

GA503 型可燃气体探测器系列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，采用挂片壁挂安装方式，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。可以检测天然气、液化石油气，人工煤气.

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，无线型还可以发射无线报警信号给相应的报警主机。 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

DESCRIPTION
The gas detector is designed for single station use or for connecting to fire alarm or
security alarm panel. 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), coal gas. The unit is designed for wire-in or plug-in applications. The gas
detector 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.
FEATURES
l Detect all sorts of combustible gases, natural gas (methane), bottled gas
(propane), LPG (Liquefied petroleumGas), LNG (Liquefied natural gas), coal
gas, including town gas.
High quality durable catalytic
combustion method gas sensor.
Easy to install.
Loud 85dB alarm and LED warning light.
Self diagnostic function by MCU intelligent software.
Excellent reliability & High stability.
Ideal for all house and kitchens.
