FOR THE INSTALLER:
Please follow carefully the specifications relative to electric and security systems realization
further to the manufacturer’s prescriptions indicated in the manual provided.
Provide the user the necessary indication for use and system’s limitations, specifying that the-
re exist precise specifications and different safety performances levels that should be proportio-
ned to the user needs. Have the user view the directions indicated in this document.
FOR THE USER:
Periodically check carefully the system functionality making sure all enabling and disabling
operations were made correctly.
Have skilled personnel make the periodic system’s maintenance. Contact the installer for ve-

to protect due to extension, change of the access modes etc…)
......................................................
This device has been projected, assembled and tested with the maximum care, adopting con-
trol procedures in accordance with the laws in force. The full correspondence to the functional
characteristics is given exclusively when it is used for the purpose it was projected for, which is
as follows:
Microprocessor based control units
Any use other than the one mentioned above has not been forecasted and therefore it is not
possible to guarantee its correct operativeness.
The manufacturing process is carefully controlled in order to prevent defaults and bad func-
tioning. Nevertheless, an extremely low percentage of the components used is subjected to faults
just as any other electronic or meccanic product. As this item is meant to protect both property
and people, we invite the user to proportion the level of protection that the system offers to the
actual risk (also taking into account the possibility that the system was operated in a degraded
manner because of faults and the like), as well reminding that there are precise laws for the de-
sign and assemblage of the systems destinated to these kind of applications.
The system’s operator is hereby advised to see regularly to the periodic maintenance
of the system, at least in accordance with the provisions of current legislation, as well as
to carry out checks on the correct running of said system on as regular a basis as the risk
involved requires, with particular reference to the control unit, sensors, sounders, dial-
ler(s) and any other device connected. The user must let the installer know how well the
system seems to be operating, based on the results of periodic checks, without delay.
Design, installation and servicing of systems which include this product, should be made by
skilled staff with the necessary knowledge to operate in safe conditions in order to prevent acci-
dents. These systems’ installation must be made in accordance with the laws in force. Some
equipment’s inner parts are connected to electric main and therefore electrocution may occur if
servicing was made before switching off the main and emergency power.
Some products incorporate rechargeable or non rechargeable batteries as emergency power
supply. Their wrong connection may damage the product, properties and the operator’s safety
(burst and fire).
