Description
The 452T is a versatile unit that can meet door lock and other unique installation needs. It can be used as a door lock pulse generator to convert a positive or negative latching input to door lock and unlock pulses. The 452T can provide either 200mA (-) or 200mA (+) pulses for door locks, making it possible to control any relay driven factory lock system without any additional parts. Common applications include adding door locks to a unit that has a ground-when-armed output, or generating pulses for ignition controlled door locks. The 452T can also generate two separate pulses from a single pulse input. Some newer vehicles require two pulses to unlock the doors such as: newer Nissan vehicles, Infiniti vehicles, and Volkswagen vehicles.
