The DoorProtect Plus S offers wireless detection capabilities, promptly alerting you to initial signs of room intrusion via open doors or windows, shocks, or tilts. Versatile in application, it can be securely mounted on various door types, including those with metal bases. Utilizing a high-end British-manufactured reed switch, the device detects door or window openings through magnetic field activation. Additionally, it can function as a transmitter, sending signals from a wired sensor to the hub.

This device also safeguards open windows used for ventilation. Equipped with an accelerometer, it detects changes in vertical slope angle, impacts, or vibrations, promptly sending alarms to the hub for immediate attention.

Ready to operate straight out of the box, the DoorProtect Plus S battery is already installed, therefore there is no need to disassemble the detector. With one click, it can be connected to the hub via the mobile application.
