3) Installation
The KEYPAD and READER cases are protected to IP 54 and can
therefore be installed outdoors. Install as shown in figure 4 or 5.
!
The READER uses the magnetic induction principle to
recognise the CARDS; do not install it on metal or metal-
bearing surfaces, otherwise these will absorb a large part
of the magnetic field and the distance at which the CARDS
can be recognised will shorten to just 1-2 centimetres.

If you have no choice, insert a plastic support at least 2 cm
thick between the metal surface and the READER to obtain
a reading distance of about 4- 6 cm.
The DECODER, instead, is protected to IP 30 and must therefore be
installed inside adequately protected control centres or panels.
