Claim:
1. A multipoint mortise lock mechanism for a swinging door, comprising: a central cassette assembly operably coupled to at least one 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 and an anti-slam mechanism; the anti-slam mechanism including an anti-slam plunger that when in an extended position engages the remote locking linkage and thereby inhibits movement of the remote locking linkage so that deployment of the remote locking point assemblies is prevented, wherein the anti-slam plunger comprises a rotatable paddle and a detent, the rotatable paddle being shiftable between a first position in which the paddle presents a first sloped surface in a first direction and a second position in which the paddle presents a second sloped surface in a second opposing direction, the detent holding the paddle in either of the first position or the second position; and 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.
