A tilt latch system that comprises an actuator movable from a first position to a second position; a lock-out member movable from a retracted position to an extended position upon movement of the actuator from the first position to the second position; and an engagement member movable from an engaged position to a disengaged position upon movement of the actuator from the first position to the second position is provided. The actuator and the engagement member are maintained in the second and disengaged positions, respectively, when the lock-out member is in the extended position. The actuator and the engagement member are automatically biased to the first position and the engaged position, respectively, upon movement of the lock-out member from the extended to the retracted position. The tilt latch system may further comprise a lock-out device and/or be optionally utilized in a modular configuration.
