Here's the description:
Our power window controller is designed with a two button interface for raising or lowering an electric motor powered automobile window. The power control to the motor is by a relay. The system features an over current sensor which prevents motor overloading or burnout. This is also used to detect window jams or obstruction.
A separate input is provided to sense the central locking signal from any car alarm system and automatically raise all windows. The system will need to be customised for a specific car type or window and we will need technical info regarding the type of motor used. An additional feature is implementation of delay timing for each window which ensures that all windows do not go up simultaneously.
Also found something at Crutchfield's:
Crime Guard Au93-4
4-window Roll-Up Module
Add-On or Stand-Alone Operation: This module can be used as an add-on to an aftermarket alarm system, or it can be connected as a stand-alone device. As an add-on, the module can be connected to work with a remote controlled alarm output, or it can be connected to a starter disable output that is active whenever the alarm is armed. If you connect the unit to an alarm's starter disable output, the windows will be automatically rolled up whenever the alarm is armed. When used as a stand-alone device, the module can be manually triggered with a toggle switch (not included), or a relay (not included) can be connected to trigger the module when you turn the ignition off. When a relay is connected to trigger the module when the ignition is turned off, the windows will be automatically rolled up every time you turn off the vehicle.
