Detailed Description
Product Description Technical standard 1. Optics standard Visual angle: 60° The largest coverage: 2*8m Bracket adjustable angle: -45°to +45°(horizontal line) Bracket adjustable angle: -45°to +45°(vertical line) 2. Electricity standard Power requirements: 45μA (while monitor) Power requirements: 7~8mA (while sending) Lifespan of battery: can use half year if send 20 times everyday 3. Wireless sending standard Working voltage: 9V to 12V Frequency: 315MHz Deviation of frequency: ±0.2MHz Sending consumption: 10Mw Temperature: -40℃ to +80℃ Address code, data code: According to installation that offered by host 4. Environment standard Working temperature: -10℃ to 50℃ Keeping temperature: 20℃ to 60℃ Capacity of anti-interference(electromagnetic): If it is 1000MHz, more than 30V/m 5. Physics standard Dimension: 110mm(Long)×65mm(Wide)×48mm(High) Color: White Installation of bracket and battery In order to install and adjust conveniently, we provide bracket. You should fix the bracket with screws on the position that has been selected first before use. And then install the battery into the PIR. It will enter into normal working status in five minutes. Selection the position of installation The position should be in the monitored areas. The height of installation is about 2.1m, relative to the alarm area of PIR. In order to avoid wrong alarm in the largest limit, we should notice whether it is day or night, avoid a direct ray of light on the PIR. PIR works on the condition of inducing the infrared light of moving objects and infrared energy's difference of background objects.To acquire the largest sensitivity, we suggest that the PIR should fix forward to the lowest temperature position of guarding area.
