PRODUCT MAINTENANCE
In general, the products in the range Nice Home Security do not require special
maintenance; in any event the surfaces of the products should be cleaned, and
in particular of the detectors, on which the sensitive elements (sensors) must be
kept free of dust and other contaminating substances at all times (see respec-
tive instruction manual).
Warning – For cleaning the product surfaces, use a slightly damp (not wet)
cloth; use water only and never detergents or solvents.
An alarm system does not normally signal alarm conditions for extended peri-
ods of time and for this reason correct operation is not always verified.
The control panel is equipped with a series of functions to maintain and check
system efficiency:
• Possibility of checking components in the alarm system by means of the sys-
tem "TEST" function (see chapter 9.2.5). Periodic checks of system opera-
tion are recommended.
• The control panel records all events and stores the last 200 events in the
memory (see chapter 9.2.5.1). The analysis of the event log can be useful to
check and possibly prevent the causes of malfunctions.
• The control panel indicates the charge level of a number of associated
devices. All battery-powered devices have a function that checks the battery
charge status; when the remaining autonomy is approx. 15-30 days, the "low
battery" status is indicated. This occurs both on the device (see respective
instruction manual) and on the control panel.
Warning – When the low battery signal is present, the battery must be
replaced as soon as possible.
• The mains-powered devices have a rechargeable backup battery (not sup-
plied) which is activated in the event of a power failure. The average lifetime of
this battery is 4-7 years (decisive factors include environmental temperature,
frequency and intensity of use).
It must be replaced at the end of this period. Otherwise a practical test of sys-
tem duration must be performed: disconnect the mains power supply and
check how long afterwards the low battery signal is activated. Replace the
battery when the time is half that of the normal value or less than the required
service time.
Caution! – When batteries are partially discharged, the radio range between
devices is reduced and system operation is not guaranteed.

7.1 - Replacing the batteries (control panel and accessories)
When the battery pack or backup battery of the control panel or those in the
accessories are discharged, they must be replaced to restore efficient system
operation.
Caution! – Never use new battery models different from the specified
version.
To replace the control panel battery proceed as follows:
Caution! – Before opening the control panel housing, to avoid undesired
activation of alarm signals, the unit must be set to TEST mode (see chap-
ter 9.2.5.1) and the mains power must be disconnected (for models
HSCU1GC and HSCU1C).
For models HSCU1GC and HSCU1C (backup battery):
01. Open the box (fig. 41);
02. Detach the backup battery from its seat (fig. 42) and replace with an iden-
tical version. Caution! – Observe the indicated polarity;
03. Close the box (fig. 44);
For models HSCU1G and HSCU1 (battery pack):
01. Open the box (fig. 41);
02. Detach the battery (fig. 43) and replace with an identical version.
03. Connect the new battery:
04. Close the box (fig. 44);
After closing the control panel, restart the control panel and reprogram at least
the time and date for the internal clock (see chapter 6.1).
