DC111 Magnetic Contact Installation Sheet

EN: Installation Sheet
Description
DC111 is a triple biased surface mounted magnetic contact
that can be connected to a burglar alarm system. For
additional security it also includes a magnetic field tamper and
pry-off tamper. DC111 can be used on ferromagnetic and non-
ferromagnetic environments and doors.
Mounting
The magnetic contact and the magnet should be mounted
parallel to each other and with the text facing the same
direction, using screws.
If pry-off tamper supervision is required, mount the tamper
plate (item 1) in the desired position using two middle holes
(item 2), and then mount the contact. To align the contact and
the magnet positions, if necessary, install the magnet on the
magnet spacer plate (item 3).
Note:
The tamper plate (item 1) contains a separate magnet.
Do not replace it by the magnet spacer plate (item 3),
otherwise the pry-off tamper supervision will fail.
Because this is a triple biased contact, there is a minimum
mounting distance between the magnetic contact and the
magnet. This distance is:
•
For non-ferromagnetic material: minimum of 10 mm
between magnetic contact and magnet.
•
For ferromagnetic material: minimum of 8 mm between
magnetic contact and magnet.
During installation the switching distances have to be
individually determined for each contact.
When the installation is completed, the electrical switch
function of the magnetic contact must be checked (for
example, with a continuity checker or multimeter). Use of
mechanical force, for example, when installing, can damage
glass bodies of reed switches.
Note:
When installing the contact please keep in mind that the
doors can bend under temperature influence.
