apreciate the responses, The customer is a hospital that locks down a door except for a proxy reader or keypad that releases a maglock & uses a horton automatic door opener to open the double doors if someone either: hits the press to egress button from the inside, has a proxy device , or enters a code. they would like to have a key switch located at the nurses station for manually unlocking door(maglock) at various times of the day(cannot schedule open)It should be a make break to the maglock. if my thinking is right , mostly do phone systems so need a little confirmation that I am thinbking correctly, a lot of great minds on this site, thanks in advance
