Multiple point door locking system

A door lock system comprising a first rotary configured to control extension and retraction of the deadbolt via a primary cam mechanism; a second rotary control configured to control extension and retraction of the latch; and a link configured to retract the deadbolt in response to operation of the second rotary control when the latch is retracted by the second rotary control. The link is configured to move along a linear path normal to the movement of the deadbolt and the door latch and to contact the primary cam mechanism upon the link movement to affect deadbolt retraction and extension. A lever may be used to retract the latch in response to rotation of the first rotary control in a first rotational direction when the deadbolt is retracted by the first rotary control.
