Abstract
An exit bar for securing a door has a housing adapted for mounting to a door. A push pad for receiving a push force is mounted to the housing. A latch extends from the housing to releasably latch the door to which the exit bar is mounted. A link system links the push pad to the latch so that a push force exerted on the push pad releases the latch. An electromagnetic lock disposed in the housing locks the link system to prevent releasing of the latch. The electromagnetic lock employs an electromagnet and a movable armature to lock the link system. The exit bar further delays unlocking the link system for a preestablished delay time after the push pad has been pushed.
