Description:
Adopting advanced digital signal processing technology, Compounding of high precision passive infrared detector and logical digital circuit design, feature intelligent power save, auto- temperature compensation, low battery alarm and so on. It emits wireless    digital signal to start the control panel for alarm through detecting human being body infrared heat. Nice looking, Reliable and fine quality.

Function:
1. Tamper switch: it will send alarm signal if cover is disassembled
2. Preset coding with the control panel: Switch the protection zone to "ON"  press the tamper switch and send wireless signal, the control panel sounds, it means that coding is completed matched.(refer to the  coding program of control panel operation instruction and relative detector).
3. Low battery alarm: when battery is low voltage, the human being body moving, LED flashes five times. In static environment, it is not activated.
4. Coding address: preset by manufacture or by user.
5.Protected time choosing: 3 seconds or 30 seconds, it is preset by playing pins.
6. Compatible with many control panel.
