A universal interface for controlling power door locks with an automobile burglar alarm which automatically locks or unlocks any automobile's power door lock/unlock system in response to the arming and disarming of any automobile burglar alarm, including timers to control the length of the lock and unlock signals, a latching memory circuit to remember what the last operation of said interface was in order to determine whether to lock or unlock the automobile's doors, and a circuit to prevent any signal from interrupting the locking operation but allow a lock signal from said alarm to have priority over an unlock signal. A-B connects to the battery. C-D to the arm/disarm output from the alarm. E-H transmit lock/unlock signals to the door locks following presettable delays determined by timers T1/T2 and polarity by connections I, F, G and J. <IMAGE> |
