Monitoring contacts
Introduction
There is a difference between the three basic monitoring
contact designs:
Bolt switch contacts
Bolt switch contacts are suitable for monitoring the
locking status in doors. The bolt switch contact is fitted
into the strike plate in the frame in such a way that
it is activated by the lock bolt. The signal can be evaluated
or displayed in alarm systems, building monitoring
systems, control panels, and visual and acoustic
alarm devices. Special strike plates are available for use
in combination with electric door strikes (see Electric
Strike Catalogue).
Adjustable door contacts
Door contacts are suitable for monitoring door and
window statuses. The door contact is normally fitted
into the door or window frame. When the door or
window is closed, the door contact is mechanically
activated and the signal can be evaluated in a monitoring
system.
Magnetic contacts
A magnetic contact is a detector device for monitoring
doors, windows or other movable parts. The
magnetic contact consists of a reed contact and a
permanent magnet. When the door or window is
opened, the reed contact is opened as the magnet is
taken away, the magnetic field altered and the signal
line interrupted.
Magnetic contacts are also available in a waterproof
design, such as IP 67. They are then sealed in an
impact-proof plastic housing.
