Abstract: Operating circuits for a solenoid actuated locking means mounted interiorly of a garage door, to provide additional security. The operating circuits are electrically connected to the solenoid operator of a normally closed hasp that cooperates with the garage door in the closed position. The circuits are designed for use with an automatic garage door opener or a manually opened garage door, and include integrated circuit logic, relay logic, or equivalent means to allow opening of the garage door by authorized means, or if a forced attempt is made, or an unauthorized means is used, to open the garage door, when the garage door is in the secured position, the circuitry will activate an alarm, or other security means and prevent the garage door from being opened.
