4.4. MASONRY PREPARATIONS
4.4.1. CHASE FOR THE MAGNETIC LOOP
Fig.8 shows the realization of the magnetic loop chase. The
corners must be cut at 45°, as shown in the figure, to prevent
the cable breaking in the corners. After the cable has been
laid, the chase must be sealed with bitumen.
Realize the case at a distance of at least 15 cm. from metallic
objects (pits, grids, etc.).
If the pavement is still to be made, prepare a cable duct (if
possible with a plastic duct in one of the loop corners) and
calculate its depth according to the thickness of the finished
pavement (when pavement jobs are finished, the loop must
be at a distance greater than 5 cm from the surface).
4.4.2. MASONRY OF THE FOUNDATION PLATE
1) Assemble the foundation plate as shown in fig.9.
2) Make a foundation plinth as shown in fig.10 and wall the
foundation plate supplying one or more sheaths for
routing electrical cables. Using a spirit level, check if the
plate is perfectly level. Wait for the cement to set.

3) Prepare the electric cables for the connection as indicated
in Chapter 3.1, 3.2 or 3.3 according to the type of use. For
easy connection, let the cables come out of the foundation
plate hole for approx 1m. .
4.5. FASTENING
Make sure that the foundation plate is correctly secured and
that the cement has set. Unscrew the plate nuts and fasten the
Token Acceptor routing the cables from the inner part of the
base to the door.
5. ELECTRICAL CONNECTIONS
5.1. PEDESTRIAN ACCESS
In the configuration for pedestrian access management there is
a microswitch with 2 potential-free contacts, N.O. and N.C., to
send the Open command to an automated system.
The terminals are positioned as shown in fig.11.
