      • Home Security Magnetic Contact Installation:

        • One way to secure a home is to install magnetic contacts on doors and windows. These devices consist of a pair of magnets wired into a home-security system. When the magnets are separated (either from a door opening, or a window sash being lifted), the sensor alerts the main security panel of the fault. Magnetic contacts are easy to install and can help improve your family's peace of mind

        Door Contacts:

        • Door contacts are typically mounted along the top edge of the door, on the safe side of the door, opposite of the hinges. This placement allows for the magnetic sensor to trip after the door is open just a few inches. Mounting the sensor by the hinges might not provide enough of a gap to trip the alarm, even if the door is opened enough to allow an intruder to gain entry

        Window Contacts:

        • Magnetic contacts on windows work best on windows that have moving sashes. Contacts are often mounted along the center of the window, with half the magnet on one sash and half on the other so that the alarm will trigger if either pane moves. For large picture windows, install a glass-breakage sensor in addition to magnetic sensors. Do not expose sensor wiring in a way that may encourage a determined intruder to cut wires or to break a small pane of glass to simply unscrew the sensors from their mounts

        Wiring and Mounting:

        • Even the best-quality equipment is useless if the magnetic sensors are mounted insecurely, or if the wiring is exposed. Always sink security sensors firmly into studs or masonry with heavy-duty screws. If possible, use screws that require bits other than flat- or Phillips-type drivers. Run wiring inside of walls where possible, or protect it with metal conduits

        Power:

        • If the magnetic contact uses electromagnet technology, plan for possible power failures. The security system should have its own residual battery backup to provide protection even during utility outages. Avoid using wall plugs for do-it-yourself electromagnetic sensors, and avoid wiring different parts of the security system into different household circuits, as a breaker trip in one circuit may "confuse" the alarm system and cause false alarms
