Door Window Sensor(Anti-masking)
Door window detector is designed to detect intrusion, offering comprehensive coverage for doors, windows, skylights. The detector has two reed switches as opening sensors and a magnetometer that recognizes magnet spoofing. The device also detects shock and tilt with a built-in accelerometer.

1. Detection Performanceβ
Detection methodβ
- Reed switch*2
- Accelerometer
- Magnetic sensor
Detection Gapβ
17 mm
2. Featuresβ
Door Status detectionβ
- Door open
Alarm will be triggered when system is armed, ignores vibrations lasting up to 0.15 s.
- Shock
3 levels, Low/Normal/High, alarm will be triggered when detects a shock.
- Tilt
Tile threshold can be set from 5Β° to 25Β°, once angle exceeds the threshold, alarm will be triggered when system is armed.
Indicatorsβ
- Alarm: Flashing
Red - Find me: Flashing
Green - Signal strength:
- Flashing
Green: signal strength is strong, and is recommended to install device here - Flashing
Orange: signal strength is medium and device can be installed here - Flashing
Red: signal strength is bad or no signal, and device can not be installed here
- Flashing
Anti-maskingβ
Magnetic masking sensor
Alarm will be triggered when system is armed.
Anti-masking testingβ
- Keep the magnetic door sensor in a closed state and test for 20 seconds to obtain the normal magnetic attraction range.
Tamper Protectionβ
- Rear
Remote setting and testingβ
- It can be turned on or off from RB Link App, it is enabled by default.
Advanced featuresβ
Power up enrolling
When sensor is powered up, it will automatically start paring to the hub nearby
Find me
When enabled, the sensor starts flashing green, which can help identify the sensor from numerous Door Window Sensors.
Signal strength detection
When enabled, senor starts flashing green/orange/red showing the wireless signal strength between the hub at current installation site.
Low battery notification
3. RBF wireless technologyβ
Wireless signal rangeβ
- Up to 1,400 m in an open space with hub
- Two-way communication with hub
Frequency bandsβ
868MHz version: 863 ~ 870 MHz
915MHz version: 902 ~ 928 MHz
Depends on sales region.
Wireless signal modulationβ
- FSK / DSSS
Encrypted communicationβ
- All the data transmitted are protected by AES-CCM encryption with a random key.
Frequency hopping (FHSS)β
- To prevent radio interference and radio signal interception.
Time division multiple access (TDMA)β
- With the help of clock synchronization technology, hub will slice time into different division for different RBF wireless devices. In this way, all devices will communicate with hub in a sequence.
