Multi-point mortise lock mechanism for swinging door

A multipoint mortise lock mechanism for a swinging door, comprising:

• a central cassette assembly operably coupled to an upper remote locking point assembly and a lower remote locking point assembly by a remote locking linkage;
• the central cassette assembly including a housing, a deadbolt mechanism, a latchbolt mechanism, a remote locking point mechanism, an anti-slam mechanism, and a handle mechanism operably coupled to the latchbolt mechanism and the remote locking point mechanism, the handle mechanism including a rotatable handle;
• the anti-slam mechanism including an anti-slam plunger that when in an extended position engages the remote locking linkage via a boss and a slot and thereby inhibits movement of the remote locking linkage whereby deployment of the remote locking point assemblies is prevented;
• the deadbolt mechanism including a deadbolt extendible from the central cassette and being independently operable from the remote locking point mechanism, the deadbolt mechanism further comprising an anti-back drive mechanism, wherein the deadbolt mechanism further comprises a deadbolt driver having a first portion coupled to the deadbolt that extends the deadbolt upon shifting from a first position to a second position and a second portion that engages a stop bar and shifts the stop bar to block rotation of the handle when the deadbolt driver is in the second position.
