Electronic access control strikeand preload resistant module therefore

A preload resistant module for an electronic access control strike, the preload negating module having a frame mountable to a frame of the electronic access control strike, a motor mounted to the frame and connected to a pivotable member, the pivotable member being pivotable by the motor in a manner that when the frame of the preload negating module is mounted to the frame of the electronic access control strike, the pivotable member is pivotable into interference with a keeper of the electronic access control strike to exert a preload negating force against the keeper.

A method of operating an electronic access control strike having a socket area, a bolt path leading to socket area, a keeper movably mounted to a frame in a manner to be moveable into and out of the bolt path, a cam member moveable for selectively blocking or unblocking the movement of the keeper out of the bolt path, an actuator for driving the movement of the cam member, an anti-preload member moveable into interference between the keeper and the cam member, a motor controlling the movement of the anti-preload member, the method comprising:

• receiving a user input, authenticating the user input against credential data, and contingent upon said authentication:
• operating the actuator to move the cam member for unblocking the movement of the keeper while the anti-preload member is in interference between the keeper and the cam member.
