摘要: A exit bar for securing a door has housing adapted mounting to door. push pad receiving force is mounted the housing. latch extends from releasably which mounted. link system links so that exerted on releases latch. An electromagnetic disposed in causes an armature engage retract The further dogs unlatched position as long power control electromagnet receives operate signal and preestablished delay time after been removed.
