Wireless Magnetic Open, Shock and Tilt Detector

SAFE Door Guard Plus

Door Guard is a modern wireless magnetic door opening detector designed specifically for indoor use. This reliable helper is ideal for securing windows and doors of all types and designs. Thanks to its encrypted communication protocol, SAFEKeeper ensures a secure connection to the central control unit of the SAFE security system. Its exceptional range of up to 1,200 metres in open areas ensures efficient and stable communication. The detector is powered by a replaceable battery that allows continuous operation for up to 4 years, making it a practical and long-term solution for protecting your facility. This product is manufactured in two color variants.

Description of the Device

Small but Powerful

Door Guard Plus is a sophisticated security device that consists of two key components: a detector with an integrated, highly reliable reed relay that can handle up to an incredible 2 million opening cycles, and a powerful permanent magnet. The detector is simply installed on the moving part of the window or door, while the magnet is fixed to the fixed frame. The principle of operation is based on a magnetic field - as soon as the magnet moves away from the detector, the reed switch is activated. In addition to the reed switch, it also contains a three-axis accelerometer for detecting shocks and angle changes.

Plus in the Form of an Accelerometer

This advanced detector is equipped with an accelerometer that can detect changes in vertical tilt angle, shocks, or vibrations. Thanks to this, it not only reliably protects windows left open for ventilation, but is also able to detect vibrations or impacts that may signal an attempt at forced entry or manipulation of the magnetic contact. Door Guard Plus, however, offers much broader applications. In addition to monitoring the status of doors and windows being open or closed, it can also be used to track movement or changes in position of other objects, such as paintings, safes, or other valuable items. In the event of sensor activation, an alarm signal is immediately sent to the central unit of the SAFE security system, which then alerts the user to potential danger.

Supports System Expandability

The Door Guard Plus also features an NC input on the back for connecting an external wired detector. This input allows for easy integration of other security features, including devices from third party manufacturers. This could be, for example, a flammable or explosive gas detector, an armored contact for opening and closing the garage door, a flood detector, a wired magnetic contact, or other normally closed circuit sensors. This feature greatly increases the flexibility and modularity of the entire ProSAFE alarm system.

Smart Security

The Door Guard universal magnetic contact reliably detects the opening or closing of windows and doors and immediately informs the user of the change of status via the ProSAFE mobile app on the phone. In addition, it easily becomes part of your smart security solution - for example, it automatically triggers an alarm scenario in the event of an intrusion and activates lighting or triggers another pre-set scenario to suit your needs. This ability to combine open detection with an immediate response to an emerging event thus represents a new level of protection for your assets and increases the effectiveness of your security measures.
