These are the door contact sensors that are in use with any
and all commercial or residential card access systems as well as all security
burglar alarm system. The door position switches operate with a built in
internal magnetic reed switch that closes when the opposing magnet comes within
¾” of the door sensor. Hence when the door opens beyond the ¾” point the door
position switch will change from a closed signal to an open signal. When this
happens the access control system or alarm system will sense the change in
continuity and will know that the door or window has been opened. When the door
or window shuts, the door sensor will notify your security system that the
opening has been closed.
