ROLLING-CODE
AUTHENTICATION
A further guarantee of security regarding the signal transmissions from Air2 remote-controls
is provided by the use of a rolling code algorithm. This allows the transceiver module to check
the validity of each wireless keyfob transmission.
In the event of irregular wireless activity, denial-of-request will be signalled by an audible
error signal (“bop”).
To reset the transmissions and rolling code it is necessary to press and hold keys “
F3 ” and
“ F4 ”.simultaneously.
The function is active at default but can be disabled during the programming phase. The
deactivation can be useful to the installer when the same wireless command device is used on
several systems.

Air2-MC200 magnetic contact
The Air2-MC200 is supplied with a magnet which is to be secured (by means of two screws) to
the side of the contact, in the position indicated by the two notches.
The Air2-MC200 integrates shock and tilt sensors that allows its use without the need of the magnet.
The Air2-MC200 is equipped with open and dislodgement tamper protection.
The device uses separate channels for the different types of signalling,, thus allowing precise
identification of the alarm source.
Note
The shock and tilt sensors are not subject to certification of this product.
