Abstract
A 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 disposed in the housing causes an armature to engage the link system to retract the latch. The exit bar further dogs the latch in the unlatched position as long as the power control system for the electromagnet receives an operate signal and for a preestablished delay time after the operate signal has been removed.
