GE Series Gas Detector with Battery Backup Design

Introduction

GE series Gas leak alarm is a kind of wall-hung household gas alarm designed to detect
the concentration of combustible and toxic gases or vapors. It provide a visual and audible
signals when the gas concentration reaches presetting level, remind you take prompt
favorable action, you may start up other link equipment, ventilate gas or shut off gas supply
to avoid Fire, explosion, suffocation, and other evil accident. The alarms are available for
liquefied petroleum gas (LPG), natural gas (Methane), propane, Hydrogen, town gas,
smoke, etc. They are not only installed at home, but also used at any other potentially
hazardous areas.

MCU control, Reliable without false alarming
Locale sound and light alarming，Drive Long-distance Alarming System
Ventilate good air circulation or shut off gas supply link equipment

Operating Manual

1

、Fix gas alarm on the wall or Roof near the gas cooker or other sources within 2-4m interval. according to gas sources

Character, Choose alarm location as follows:

·LPG：Fix it within 0.3 meters above the ground (LPG is heavier than Air)

·Coal Gas, Natural Gas ：Fix it within 0.3 meters below the Roof ( Combustible gas is lighter than Air)

·Avoid such installation ：Windows with strong wind, Exit、water fog and drop place；easy polluted or high tem

environment near Oven, covering around。

2、Connect the Power supply, (If need ventilate fan, electrovalve other link equipment, please connect corresponding

circuit firstly.) Preheat the alarm 1 min, the alarm without detecting function.1 MIN later, the alarm enter into
detecting status.

3、If the flammable gas in the air reaches the preset alarming concentration, the alarm enter into alarming status, the

Alarm red LED light or flash, the buzzer give sound alarming, drive the relay or valve shut off gas supply, If the
alarm connect the ventilation fan or other relative electronics, it also open automatically, ; At the same time, please
cut off gas supp ly promptly, open the window, ask professional worker to remove the fault, The alarm with gas cut
off valve type shall output one close pulse signal.

In the interest of continued product improvement, we reserve the right to change design features without prior notice
