For The Installer - Gewiss 20 Serie Manual De Usuario

FOR THE INSTALLER:

Carefully follow all operating regulations applicable to the installing of electrical and security system, further
to the specifications supplied by the manufacturer in the instruction manual which comes with the products.
Provide the operators with all the instructions for use and the limits of the installed system, specifying that
there are specific standards and different levels of safety performance that must be adjusted to the relative user
requirements.
Make sure the operator acknowledges the warnings provided in this document.
FOR THE OPERATOR:
Periodically and carefully check that the system is functional and the enabling and disenabling procedures
are performed correctly.
Perform period maintenance on the system using specialised personnel who have the qualifications foreseen
by the laws in force. Ask the installer to check the adequacy of the system if any operating conditions change
(e.g. variations in the extension of the areas to be protected, change in the access procedures etc...)
This device has been designed, built and tested with maximum care, adopting control procedures which all
conform to the regulations in force. Full compliance of the functional characteristics is exclusively achieved in the
case where its use is limited to the functions it was designed for, and that is:
for wireless burglar alarm systems using GW 20470 and GW 20471 control units
No other use or implementation is contemplated and it is therefore impossible to guarantee it will function
correctly.
The production processes are carefully supervised to prevent defects and malfunctions; nevertheless the
components used are subject to extremely low percentages of faults, as in the case of all electronic or
mechanical part. Due to the destination of use of this device (protection of persons and things) we invite the user
to adjust the levels of protection provided by the system to the actual risk levels in loco (assessing the possibility
that this system can operate in a degraded manner due to malfunctions or faults etc) bearing in mind that there
are precise regulations foreseen for the planning and installation of systems destined to this type of application.
The attention of the operator (system user) is recalled to the need to perform regular periodic
maintenance on the system, and at least comply with what foreseen by the regulations in force, and also
check, at intervals which are appropriate to the risk levels, that the system functions correctly, testing
the signals on the control unit, the sensors, acoustic alarms, telephone combiners and all other
connected devices. On completing the periodic controls, the operator must promptly notify the installer
of the results.
The planning, installation and maintenance of the systems incorporated in this product are reserved to
personnel who are duly trained and qualified to operate in a secure manner in compliance with accident
prevention regulations. It is essential that they are installed in compliance with the regulations in force. The
internal parts of some devices are connected to the mains and therefore there is a risk of electrocution in the
case where maintenance operations are performed without disconnecting both the primary and emergency
power supplies. Some products use rechargeable or normal batteries for emergency power supplies. If they are
connected incorrectly it could damage the product, damage things and endanger the situation of the operator
(explosions and fires).
