Overhead door contact
An overhead door contact is a device used in the burglar alarm industry to detect when a door is opened or closed. It is typically installed on the top of a door frame and consists of a magnet and a switch. When the door is closed, the magnet and switch are in close proximity, which completes a circuit and signals to the alarm system that the door is secure. When the door is opened, the magnet and switch move apart, breaking the circuit and triggering the alarm.
Overhead door contacts are commonly used in both commercial and residential settings to protect against unauthorized entry. They are particularly useful for securing large doors, such as those found in warehouses or garages, as well as for securing entry doors to homes and businesses. Overhead door contacts can be wired or wireless, and can be integrated with other security devices, such as motion sensors and cameras, to provide a comprehensive security solution.
