Greensen wireless security detector,12V DC Coal Gas Natural Gas Alarm Leak Detector Home Security Alarm Gas Sensor , smoke detector

Description:  
This product uses a unique structural design and optoelectronic signal processing technology, with features such as dust, pest control, resistance to external light interference, and so on, having high sensitivity and stable performance. This product has a good response to combustible gases. Suitable for combustible gas monitoring in residential, shopping malls, museums and warehouses and other indoor environments.

Features:
Built-in unique structural design and optoelectronic signal processing technology, stable performance, high sensitivity.
Independent type suction a top installation, fireproof material, easy installation, no commissioning.
It can accurately detect or fire early smoke, having a faster response to combustible gases according to the principle of inducing combustible gas particles.
The indicator light flashes once every 8 seconds during normal operation, when the alarm occurs, the indicator light is on and the alarm output contact action occurs.
High quality and durable.

Note:
1. The detector should pay attention to dust, and the dust cover must be removed after the project is officially put into use.
2. Within 0.5m around the detector there should be no obstructers.
3. The horizontal distance from the detector to the air supply air vent hole should not be less than 1.5m.
4. The horizontal distance from the detector to the wall and beam edge should not be less than 0.5m.
5. When setting the detector on the inner walkway ceiling with a width of less than 3 meters , it is suitable to be placed in the middle.
6. The installation spacing of the detector should not exceed 15m, and the distance of the detector from the end wall should not be greater than half of the installation spacing of the detector.
7. The detector should be installed horizontally. If it is necessary to install it obliquely, the angle of inclination should not exceed 45 degrees.
8. The base of the detector should be securely mounted and its wire connection must be reliable.
