The mode of operation and the type of alert signal are selected by the user using dip-switches. Two modes of operation are possible: with automatic switching to the second stage of notification after a specified time; selection of the warning stage by means of an external control signal. The type of sound notification is selected by the user independently for each stage using dip-switch groups. Each stage has a separate group consisting of three dip switches.
