Description

WINDOW OR DOOR FOR INSTALLATION IN A BUILDING AND MONITORING SYSTEM INCLUDING A WINDOW OR DOOR SENSOR

The present invention relates to a window or a door for installation in a building, and monitoring systems comprising a door or window sensor.

The problem of improper entry into premises is a long-standing problem, and for decades electrical/or electronic systems have been proposed to detect the opening of doors or windows of homes and businesses and to activate an alarm of a given type. Although historically the percentage of homes using such systems has been relatively low, more and more such systems are being installed for retrofit in a wider range of premises.

Frequently, such systems detect the opening of a door or window using a magnetic sensing arrangement, with a magnet and a magnetic sensor, such as a reed switch. "reed switch") or a magnetometer, attached respectively to two relatively mobile parts - such as a frame and a door, or a frame and a leaf or an opening. When the door or window is closed, the magnet and the sensor are close enough to each other that the sensor is in a magnetic field of the magnet, so that for example the blades of a reed switch are kept in contact. When the door or window is opened even slightly, the magnet and sensor separate, reducing the strength of the absence magnetic field experienced by the sensor, thus causing the sensor to change state.

Detecting the opening or closing of a door in this way is of interest not only in a security context but, increasingly, in the context of so-called "smart home" installations. "). For example, in response to detecting the opening of an exterior door, a smart home may be arranged to turn on interior lights and/or home heating or cooling, and/or may be configured to turn off the air conditioning when the detection of the opening of a window.

Typically, such sensors and magnets are surface mounted on suitable surfaces of the cooperating elements, regardless of whether the system is installed at construction/commissioning of the premises or installed for retrofitting in premises which have been in use for years. Typically, an installation's magnet and sensor are mounted on surfaces that are visible even when the door/window is closed, despite the damage this causes to the aesthetics of the interior space of the premises, and, more importantly, the risk that the visibility and accessibility of the magnet and sensor will increase the likelihood of the system being sabotaged or disabled. Sometimes, however, the magnet and/or sensor may be hidden in a hole cut or drilled in one face of the frame/door/window - although cutting or drilling holes in a modern window or door can significantly impair their structural integrity and/or insulating properties, and attempts to form such holes may cause significant damage as a result of the holes being formed in inappropriate locations. Additionally, the on-site installer of sensors for a surveillance system is unlikely to know where it can be safe to remove portions of the structure of a window or door, meaning the choice is potentially between mounting the components - and even there, surface fixing may require machining holes for fixing means such as screws or rivets, and risking the structural integrity of the door or window by cutting holes to hide the components.

In some surveillance installations, a door or window may be equipped with a shock sensor rather than, or in addition to, a magnetic contact sensor, but essentially the same issues arise with the mounting of the shock sensor. shocks - although, if an accelerometer is used as the shock sensor, there is no need to provide a magnet to work in conjunction with the shock sensor.

EP3053152B1 offers an alarm kit, as part of a wireless alarm system or smart home system, which can be retrofitted non-invasively to existing building entrances , for example windows and doors, without altering the aesthetics of a home's design. An elongated sensor assembly which has a maximum height of less than 5mm is provided for cooperating with a magnet, in use the elongated sensor assembly and the magnet are configured laterally displaced relative to each other in an opening, void or cavity formed by a window or door and a corresponding frame in a closed position of the window or door. Although the proposed solution can reduce the visual intrusion presented by conventional sensor installations, not all doors or windows can accommodate such a sensor assembly. Furthermore, there is a risk of such sensor assemblies being removed by malicious persons in the event that the window or door is left open.
