According to standards of the admission of vehicles to operation each car has to be equipped with a sound signal. The system of the alarm system is intended in order that in emergency the driver could warn other participants of the movement about the compelled stop. As the alarm system has to work also at the switched-off ignition, tension on its switch moves directly from the rechargeable battery through a safety lock. Indexes of turn, on the contrary, receive tension via the ignition switch only at the included ignition. Signaling devices need to be checked always before a trip.
