Wireless Window Shock Glass Break Detector 433MHz Door Vibration Sensor with Senstitive Adjustment for Security Alarm System

Description

Functions

1.The wireless vibration sensor accurately detects vibrations from doors and windows and transmits a 433MHz wireless signal to the main hub to trigger an alarm. It must work with a 433MHz alarm host or Wi-Fi gateway and cannot operate independently.

2.It is suitable not only for door and window protection but also for safes, vending machines, garages, car doors, vehicle fuel tanks, display cases, important equipment, and valuable paintings.

3.It supports 5 levels of vibration sensitivity adjustment, minimizing false alarms caused by irrelevant vibrations such as wind or noise.

Parameters

1.Wireless signal frequency and protocol: 433.92MHz/1527

2.Wireless transmission distance: ≥100 meters outdoors in open space, approximately 50 meters indoors (laboratory test data, for reference only).

3.Power supply battery: 1 CR2032 button battery

4.Operating voltage: 3V

7.Low voltage alert threshold: 2.4V, red light stays on

8.Battery standby duration: over 2 years

9.Battery operating duration: over 1.5 years (based on a test trigger frequency of 10 times per day)

Adjust Vibration Sensitivity

1.Press and hold the SET key for 5 seconds. Release the key when the red and blue lights are on, and then it will start flashing (the number of flashes indicates the current sensitivity level of the sensor).

2.Press the SET key again to enter the next sensitivity level. The red and blue lights will flash accordingly to indicate the current sensitivity level. The sensor supports up to 5 sensitivity levels as follows:

Level 1: Minor vibration trigger (default level)

Level 2: Knock trigger; window opening will not trigger

Level 3: Long-distance strong knock trigger

Level 4: Short-distance strong knock trigger

Level 5: Close-range heavy knock trigger

Pair the sensor with the alarm host

1.Use a small screwdriver to unscrew the screws on the back of the product,and gently press the recessed area of case with your fingers

2.Toggle the battery switch to the “on” position. The red and blue lights will flash, indicating the device is powered on.

3.Follow the instructions of alarm host to enter the sensor pairing mode.

4.Once the host is in pairing mode, gently knock the detector to trigger the signal. If the blue light flashes, it means the signal has been successfully sent.

Mount the sensor

Stick one side of the double-sided tape to the back of the sensor and the other side to the door, window, or glass, ensuring proper positioning and stability of the sensor installation.
