Siren kit with battery back-up

A siren with battery backup considerably increases
protection provided by the alarm system. Should a thief be
allowed to work undisturbed, in spite of the fact that the
alarm has gone off, he can cut the power supply and
disarm the alarm. A siren with battery backup ensures that
it will continue to sound even if the battery cable has been
disconnected. The built-in battery charges during driving
in order to ensure full power when needed. The built in
battery capacity will provide a signal for at least 5 minutes.
