.Function theory of antitheft control system

1.

Power window

The main power of the control device is under control of the ignition switch. When
the ignition switch is closed for 60 seconds, it will forbid the glass to rise or drop.
The elevator control module controls four glass controllers that can sense whether the
elevating device clamps any person or material. These devices are under protection
by residual current breakers and the leakage limit will change according to the
external voltage changes. Four window controllers have function of consecutive
output of 8-second protection.
The safety switch can control whether the right front, left rear and right rear door
switches can operate the corresponding glass elevator.
Operation mode: manual elevation, decline, and automatic decline.
Manual decline: pressing time ≥ 300ms
Automatic decline: pressing time ≤ 300ms.
Note: When the glass descends automatically, if the decline switch of the glass controller
is pressed for over 300ms, the glass movement will be turned into the mode of manual
decline; if the elevation switch of the controller is pressed for over 300ms, the glass
movement will be turned into the mode of manual elevation. If the pressing time is no
less than 300ms, the glass movement will stop.

Central door lock

The left front door independently controls the locking and unlocking of central lock;
It can lock and unlock remotely;
The central door lock cannot operate simultaneously together with the glass elevator.
