Abstract:
An exit device includes a housing, a latchbolt coupled to and movable relative to the housing, and an auxiliary bolt coupled to the housing and movable relative to the latchbolt. The exit device also includes a deadlock link coupled to the housing and movable relative to the latchbolt and the auxiliary bolt between a first position, in which the deadlock link allows movement of the latchbolt relative to the housing, and a second position, in which the deadlock link inhibits movement of the latchbolt relative to the housing. The exit device further includes a spring biasing the auxiliary bolt into engagement with a portion of the deadlock link to move the deadlock link toward the first position.
