Magnetic Contacts
Magnetic contacts are two-part devices used to safeguard windows and doors.
One part of the contact is a switch installed in the window or door jam; the other
contains a magnet and is placed in the window or door itself. Any noticeable shift
in contact with the switch results in an alarm.

Ademco/Honeywell has alarm detection sensors for wired, wireless and V-Plex
applications.  Selection include surface, recessed/concealed and special mount
(Basement window) models.
