Wireless Smoke Detector and Temperature

Wireless Smoke Detector and Temperature with Low battery warning

Product introduction:
This product is a wireless photoelectric smoke detector (hereinafter called detector). It uses a specially designed structure and adopts MCU to analyze the smart photoelectric signal functions with dustproof, mothproof, anti-light interference etc, therefore ensuring stability by design. Meanwhile, it has the wireless network to a variety of environmental needs, improved user perception of the alarm signal. This product has a good reaction to slow smoldering or burning. visible smoke caused by Suitable for fire protection in residential homes, factories, shopping malls, hotels, office buildings, school buildings, banks, libraries and warehouses, etc.
 
Principle of operation:
This product uses the principle that smoke particles can reflect infrared light. The circuit consists of infrared emission, receiver and MCU processing parties. The infrared emitting diode and a receiver diode is placed in the optical chamber, which can protect against interference from external light, but will not affect the smoke into it. Smokeless receiver diode can receive very weak infrared light, when the smoke enters the chamber, due to reflection, infrared light received increased. When the smoke reaches a certain density, MCU analysis is alarm level, the alarm indicator flashes, accompanied by sharp sound of alarm, while the detector will send signals to other interconnected detectors and alarm host.

Instructions for use:
1) The following points should be avoided in the installation:
       A) places with smoke remain in normal situation
       B) places with humidity> 95%.
       C) contaminated by the larger dust, steam, oil, places etc
       D) locations with high wind speed (under 5m / s)
2) Put the battery into the battery box, select a suitable location (usually mounted on the roof of the central zone of detection), secure the mounting base on the chosen location with screws, then stuck the detector at the base and turn, and check whether it is firm.
 
heads up:
1) the automatic verification of failure of this product only refers to checking fault errors in the photoelectric infrared sensor and low battery power, the sensitivity of the sensor still needs to be tested according to the requirements.
2) Please clean the surface of the detector by soft brush for six months to ensure the sensitivity and the life of the product, and please turn off the power before cleaning.
3) If there is a failure of the product in use, please contact us, but do not disassemble or repair by yourself, to avoid accidents.
4) If it is not used for a long time, please download the detector, remove the battery and put them in the shipping carton and store in a dry and ventilated place.
5) detector can reduce the accident rate, but can not guarantee no risk at all. For security issues, and a proper use of the detector, please improve surveillance in everyday life and have a good protection.
