Hey everyone. My drawings show doors with smokes on both sides and a relay to shut door.
My assumption is that those doors will close only when either of the two smokes are in alarm.
The reason I ask is if maybe those doors close on general alarm and because they are fire doors they need to have smokes on either side.
Or is the design with the two smokes on either side to close the doors only when either of the two go into alarm.
