The Override Key Switch is designed to be installed in a secure location outside, wired in parallel
or series with the power supply and the electromagnetic lock (EM lock). If the EM lock
malfunctions due to the failure of the reader or other reasons, the user can switch between
normally closed (N.C.) and normally open (N.O.) contacts by using the key, thus forcing the door
to open. Override Key Switch is used as a backup to an access control system
