PRODUCT INTRODUCTION
The product is suitable for the safety of
residential house, villas, hotels, markets, boarding house etc.
The product is wall mounted gas detector with high
stability.(hereinafter called detector)
It is used for
detecting leaking gas. Advanced semiconductor sensor is
adopted to ensure high stability and long life. It is convenient
for mounting.

PRODUCT PROFILE
INSTALLATION
1. Please confirm the induced gas is heavier than air, or lighter
than air. The gas is heavier than air: LPG etc. The gas is
lighter than air: natural gas, marsh gas and etc.
2. Choosing the suitable position to install the Detector
according to the gas specific gravity. Detecting the gas
heavier than air: Installation height from floor: 0.3-
1.0m,Semi-diameter to gas source: <1.5m;Detecting the gas
lighter than air: Installation height from ceiling: 0.3-1.0m
,Semi-diameter to gas source: <1.5m.
3. Fix the screw into the wall firmly, then hang the detector.
4. Avoid installing the detector close to the following sources
of interference: direct air flow from vents, fans, doors,
windows, sources of steam, oil vapor, etc.
5. All wires installation must accord with the National and
Local effective laws and criteria. The wires must have the
suitable size and colorful marks for avoiding connecting
error. And unsuitable connection of wires will result in the
alarm error while gas leaking happened.
