These mechanisms give the reciprocating rod transmitting the movement to the parts of the door lock.The electrical signals generated by the control unit and is driven actuators.The block has inputs that connect the corresponding alarm circuit.
additional locking hood - is a useful accessory.After opening the hood Theft Auto has access to the most important parts of the car, and alarm.Disconnect the siren, he will be able to quickly remove the signaling and interlocking knots.If the hood is set for an additional lock, which opened with a key, and not just from the interior lever, the actions to open its hijacker will become very difficult.Among other things, this castle is a circuit that breaks the ignition.

Group Enforser Cop gave greater working distance, but had at the same time requirements for the installation of antennas.Another group Road Star were more reliable, but also more modest performance.
Messengers from lineup Secopage-35 not only fix alarms, but also determine the color indicating the cause (the opening of the hood, doors, shock sensor).
