DESCRIPTION
MC 340 is a versatile magnetic contact used in both alarm
and security access control systems for protection of doors,
gates and windows against unauthorised opening. A wide
range of accessories enables the contact to be recessed- or
surface-mounted on a variety of surfaces, including
ferromagnetic materials.
MC 340 is certified according to EN 50131-2-6:2008.
MOUNTING INSTRUCTIONS
Contact and magnet should be installed axially,
corresponding to each other.
Catch-bolts on the housing enable direct installation in
ф 8 mm holes in wood.
Appropriate accessory must be used for installation in
ferromagnetic environment.

MC 340 Instruction Manual
OPERATING PRINCIPLE
MC 340 magnetic contact has two parts: the contact part
with a reed switch and the magnet part. In its neutral
position the reed switch remains closed under the force of
the magnetic field. Opening the monitored object increases
the distance between the reed switch and the magnet. This
reduces the influence of the magnetic field on the reed
switch until it opens and activates an alarm.
Magnetic contacts should not be installed in the vicinity of
strong magnetic fields.
INSTALLATION
Detailed installation instructions can be found in MC 340
Installer Manual.
Contact and magnet should be aligned axially in the frames
and leaves of the monitored objects (windows, doors etc.).
Offset will reduce the working distances. The contact should
be mounted in the stationary part of the monitored object
(ex. door frame) and the magnet in the movable part (ex.
door leaf). Before mounting, holes must be drilled. Catch-
bolts on the housing enable direct installation in ф 8 mm
holes in wood.
For sites where it is impossible to mount the contact
directly, a variety of accessories is available.
Accessories with a strong magnet provide a bigger working
4-MC340-01
distance for more demanding applications and maintain the
parameters of the magnetic contact when mounted in
ferromagnetic environment.
Accessories for surface mounted applications provide
installation solutions for sites where recessed mounting is
not suitable.
The working distances of the magnetic contact will be
decreased in the proximity of ferromagnetic surfaces. The
closer the contact/magnet is installed to the ferromagnetic
surface, the lower the working distances
Only non-ferromagnetic screws may be used when mounting
the contact using accessories.
After the installation, use an ohmmeter to check the
electrical connections and test the function of the magnetic
contact.
Warning: applying excessive force to the housing of the
contact may damage the glass body of the reed switches
inside.
Warning: appropriate accessories must be used for
installation in ferromagnetic environment.
RESISTORS (OPTIONAL)
MC 340 is available in two additional options with resistors
of the chosen value: MC 340-R with one resistor parallel to
the alarm switch and MC 340-2R with two resistors in 2EOL
configuration
