1. A slide latching system for latching a sliding door panel to a door frame, the slide latching system comprising:
a jamb strike configured for connection to the door frame, wherein the jamb strike includes at least one strike catch and a cavity;
a latch assembly configured for connection to the sliding door panel, the latch assembly having a latch member connected to a rotary actuator, the latch member having a latch hook portion configured to engage the jamb strike, the latch hook portion being pivotable between a latched position and an unlatched position by rotation of the rotary actuator;
a handle assembly including a handle set for mounting to the sliding door panel, the handle set being drivably coupled to the latch assembly, the handle set including a base, an upper pivot arm, a lower pivot arm, and a handle pivotably coupled to the base between the upper pivot arm and the lower pivot arm about a pivot axis extending between the upper pivot arm and the lower pivot arm, the handle including an operator portion and a driver portion on opposite sides of the pivot axis, the driver portion including a beveled surface, wherein the operator portion of the handle is configured to be pulled by a user in a direction of sliding for opening the sliding door panel; and
a cam including a barrel with a driver end portion connected to the rotary actuator of the latch assembly, the cam including a cam arm extending perpendicularly from the barrel opposite the driver end portion, the cam is rotatably mounted to the base to rotate the barrel and cam arm about a cam axis, the cam arm including a driven end portion offset from the cam axis that projects outwardly from the cam arm along the cam axis, wherein the beveled surface of the driver portion of the handle is slidably engaged to the driven end portion of the cam arm, and pivoting the handle about the pivot axis in a continuous motion as a result of a force applied by the user to the operator portion in the direction of sliding for opening the sliding door panel to rotate the handle from a home position having an acute angle orientation of the handle relative to a planar extent of the sliding door panel to an actuated position having a parallel orientation of the handle to the planar extent of the sliding door panel causes the beveled surface of the driver portion of the handle to act on the driven end portion of the cam arm to rotate the cam arm and the barrel around the cam axis to rotate the rotary actuator of the latch assembly with the driver end portion of the cam and pivot the latch hook portion of the latch assembly to the unlatched position so that the sliding door panel is unlatched and the sliding door panel is opened using the same continuous motion applied to the operator portion of the handle to move the latch hook portion of the latch assembly to the unlatched position.
