2.1 NOTES FOR A CORRECT INSTALLATION
The 1061/006A control panel must be placed in a position protected by burglar detectors. If it is needed the
GSM module usage, it is necessary to verify in advance if, in the selected position, the GSM signal is good.
To check it, verify the field strength using the GSM coverage test (see
paragraph 5.4.11
).
WARNING
: For GSM network coverage check, it is necessary to use the same mobile network carrier
SIM as the one used in the GSM module. This because in the same place, coverage levels of various
mobile network carriers can be very different, or even absent.
Management keypads, electronic key readers and proximity readers must be put in dry places, protected
against bad weather conditions. These devices are daisy chained to the control panel with a single bus
cable. The sequence used to connect them to the bus is irrelevant (devices are identified by a hardware
address, not according to the connection sequence), so it is possible to use for the bus the most
convenient and the fastest path for installation.
2.2 BATTERY DIMENSIONING
The system must be sized so as to guarantee, in case of a blackout, a minimum time of autonomy (it is
suggested at least 12 hours).
Therefore, in order to guarantee minimum duration of the battery, the system powered directly by the
control panel must comply with the following requirements.

WARNING
: Use batteries with UL 94 HB class inflammability or better.
2.3 CALCULATION OF THE TOTAL ABSORPTION OF THE SYSTEM
In order to calculate the total system absorption, proceed as follows:
•
list all the necessary devices, with their quantity and maximum absorption per unit in stand-by (which
is all available from the technical specifications);
•
multiply the quantity and the absorption in order to get the subtotal for each device;
•
sum all the partial totals to obtain the subtotal;
•
add 10% to the subtotal for potential future upgrades;
•
calculate the total.
