Abstract: A latch system includes an actuation module having first and second actuation mechanisms. The first actuation mechanism includes a first handle coupled to a locking rod having an end slot and an oppositely disposed rod insert. The second actuation mechanism includes at least one second handle, a conversion block and an outer rod coupled together. The outer rod has an open end and a slot. At least one latch module has a retractable latch. A control cable connects the conversion block and the latch module such that rotation of the conversion block in a first direction retracts the latch. A lock is operably engagable with the end slot to selectively allow and prevent rotation of the inner rod. Selective rotation of the locking rod in the first direction rotates the conversion block. Rotation of the outer rod in the first direction rotates the conversion block without rotating the locking rod.

Abstract: A latch system includes an actuation module having first and second actuation mechanisms. The first actuation mechanism includes a first handle, a lock tab and an inner rod coupled together. The second actuation mechanism includes at least one second handle, a conversion block and an outer rod coupled together with the outer rod and the conversion block each having a slot. At least one latch module has a retractable latch. A control cable connects the conversion block and the latch module such that rotation of the conversion block in a first direction retracts the latch. A lock is operably engagable with the lock tab to selectively allow and prevent rotation of the inner rod. Rotation of the inner rod in the first direction rotates the conversion block. Rotation of the outer rod in the first direction rotates the conversion block without rotating the inner rod.
