KERUI Z31 Wireless Vibration Detector

Notes:
During detector installation, due to the high sensitivity setting, the installation location occurs false alarms frequently. Please properly low down the sensitivity range; if the false alarms still occurs in low sensitivity range, maybe installation location with too much external environment interference to make the detector can not works well.
1. Do not install it on the surface of metal.
2. Do not install it at the strong vibration of position.
3. This is non-waterproof product, do not install it outdoor.

Replace the Battery: 
When the detector is in low voltage, the users need buy and replace the batteries by themselves, or the transmitted signal may be weakened. Please replace the batteries in the following steps:
1. Press the top, slide and open the battery cover.
2. Take out old batteries.
3. Place the new battery, 2pcs AAA alkaline batteries, pay attention to the positive, negative charges.
4. Test the new battery: dial code sending button, the indicator light works and send the code to the alarm host.
5. Put the battery cover back and fix it well.

Overview: 
The KR-Z31 Wireless Vibration Detector adopt the advanced wireless technology, with attractive appearance design, smooth shape, very coordinated with interior decoration and blend into the installation environment. The detector is connected with the alarm host by code setting in which user programs its unique address code to the alarm host. When the vibration intensity of detector surrounding is over the limited amplitude, the transmitter launches alarm signal to alarm host at once to indicate that there is an illegal vibration. 

Features:
*Vibration Alarm Function: When the detector monitors the vibration of the surrounding over the limited amplitude, the indicator light flashes 1.5 seconds instantly, and send the alarm signal to alarm host at once.
*Low-voltage Reminder Function: When the detector is in low voltage, it will send low voltage signal to the alarm host, and the indicator light will flash 1.5 seconds. The alarm host will voice prompt: "Zone XX is in low power" to remind you to change the batteries. The detector will not monitor vibration anymore after send the low voltage signal, and the indicated light will flash 4 times for every 30 seconds until power off.
*Tamper-proof Function: There is a tamper proof button in the back of detector, when the detector is removed, the tamper button would be triggered, the indicated light will flash 2s at once and send the alarm signal to the alarm host.
*Sensitivity Switch Function: There is a sensitivity dial code in the back of detector, you can switch the different sensitivity according to installation location to suit the current environment. (3 sensitivity range switch: H-high sensitivity range, M-middle sensitivity range, L-low sensitivity range).
*Applications: It particularly applies to apartment, villa, hotel, residential, conference room and other places.
