Technical Note:

1, the induction of gas: gas, natural gas, liquefied petroleum gas LPG (gas concentration alarm: 0.1 to 0.5%; Natural gas: 0.1 ~ 0.3%; LPG: 0.1 to 0.5%) 

2, Manual Testing: alarm exclusion automatically reset after 

3 Networking: Wireless networking 

4 Alarm Output: transmitting a wireless signal, live sound and light alarm 

5, Wireless transmission frequency: 315MHz 

6, wireless transmitting distance: Accessible from 40m (open area without interference zone factory test distance) 

7, the working voltage: AC 220V (direct plug-in) 

8, Operating temperature: -10 ℃ -55 ℃ 

9, Humidity: ≤ 97% 

10, Quiescent Current: 70mA 

11, alarm current: 150mA 

12, Alarm volume: 85db 

13 Response time: 20 seconds (according to the specific gas concentration and extended) 

14, Dimensions: length 103 × width 71 × 40mm

Installation instructions:

1, alarm installation location: the gas source centered within a radius 1.5 m, well-ventilated place. 

2, liquefied gas density than air leakage after staying at a low, the alarm should be installed in about 0.3 meters from the ground. 

3, gas and carbon monoxide and other smaller density than air, staying aloft after the leak, the alarm should be installed at a distance of 0.3 m at the ceiling.

Instructions for use:

1, the alarm is energized, the green LED lights lit the red light flashes to indicate a warm-up self-test alarm state, about 2-3 minutes later, the red light is off, the alarm into the monitoring status. 

2, when the sense and intelligence to judge a gas leak, the alarm scene issued a "drip, drip ..." alarm sound, alarm red LED flashes, the scene issued a 85 db alarm sound; simultaneously transmit wireless alarm signal. 

3, the alarm is removed, the alarm automatically resume normal monitoring status. 

4, detection: alarm under normal operating conditions, the alarm press the "test" button, or continue to alarm 5-15 seconds or so holes injected into the combustible gas detector gas (usually lighter in no ignition), the alarm should be issued Sound and light alarm host to transmit wireless networking signal that functions properly.

Networking Description:

1, This product uses wireless transmitter chip PT2262, shock resistance 1.5M, firing frequency 315MHz; with the market supporting the use of most wireless alarm host (Support Our all burglar alarm host). 

2, supporting the use of the wireless alarm host, you need to set the detector 8 address code and 4 data code; such as wireless alarm host using learning code, address code A0-A7 is an arbitrary code, does not recommend full-empty, free Plug 4 address coding; data codes can all be empty, do not insert code; Then learn with alarm host settings can be used. Such as wireless alarm host fixed code, address code A0-A7 as the host product number, data code according to the instructions on the host zone settings inserted code, plug-yard completion after use. 

3, the gas detector should be all set to host the emergency zone, whether it is armed or disarmed the host, as long as the received signal to the gas detector alarm immediately in order to ensure safety.

Note: 

1, do not install the outdoor 

2, do not install in the vent, fan, door, etc. where a large amount of wind flow 

3, do not install more than -10 ℃ -50 ℃ places 

4, do not install in a very humid Local 

5, the object will not be installed on a gas alarm device with isolated place 

six, avoid use near the alarm solid hair spray, pesticides, paints adhesives, thinners alcohol 

7, often with vacuum cleaner or other methods to clean the sensor dust and oil intake

Alarm handling:

When the ambient air concentration of combustible gases concentration reaches or exceeds the alarm setting, the alarm will continue to enter the alarm state, immediately: 

1, shut off the gas pipeline valves. 

2, immediately open the windows so that the indoor air circulation. 

3, extinguish all ignition sources and all items can produce sparks. 

4, to avoid all kinds of electrical switches. 

5, promptly notify the relevant departments and related professionals handle .
