An encased magnetic reed switch is held open by a magnet so that when the magnet is moved away such as in the opening of a door or window, the switch closes. This initiates a warning sound through an inbuilt sounder. The FK506 has an optional, adjustable inbuilt timer which may be switch-selected to regulate the duty cycle of the sounder device.
