Product Information

Full details

This KERUI wireless door/window magnetic sensor (D022) is ideal for homeowners seeking enhanced security by monitoring entry points. Its key benefit is instant alerts to your paired KERUI alarm system when a door or window is opened, providing peace of mind. A potential caveat is its reliance on a KERUI host alarm system for functionality. This sensor detects separation between its two components, triggering a signal over a 433MHz frequency to the base unit.

FAQs

What type of battery does the KERUI D022 sensor use?

The sensor uses one 23A 12V battery.

How do I know when the battery needs replacing?

The sensor has a low battery indicator. The red LED will turn on when the battery needs changing.

Can I use this sensor with alarm systems from other brands?

No, this sensor is designed exclusively for compatibility with all KERUI alarm systems operating on 433MHz.

What is the maximum wireless range of this sensor?

The unobstructed communication distance to the base unit is up to 250 feet. An extendable antenna can help maximize this range.

How is the sensor mounted?

It includes double-sided tape for easy mounting directly onto doors, windows, and their frames.

What happens if the sensor's magnet is separated by more than 1cm?

When the transmitter is separated from the magnet by more than 1cm, the sensor sends an alert signal to the paired KERUI host alarm system.

Is installation difficult?

No, the wireless design and included double-sided tape make installation straightforward and tool-free.

Troubleshooting

Sensor not triggering alarm

Ensure the sensor and magnet are properly aligned and within 1cm of each other when closed. Verify the battery is correctly installed and has sufficient charge. Re-pair the sensor with the KERUI alarm system.

False alarms

Check that the sensor and magnet are securely mounted and not accidentally separated by vibrations or drafts. Ensure the gap between the two parts when closed is minimal.

Low battery indicator is always on

Replace the 23A 12V battery with a new one. Ensure the battery is inserted with the correct polarity.

Communication range is poor

Ensure the antenna on the base unit (if applicable) is extended. Minimize obstructions between the sensor and the alarm base. Check for potential sources of radio frequency interference.
