ELECTRICAL CONNECTIONS

5.1 - Important warnings

• The mains power hookup must be done by a qualified electrician in
line with electrical equipment regulations.
• Install a 2-pole circuit breaker with contact gap of at least 3 mm, or an elec-
trical cable equipped with a plug for a standard socket .
• Run some tests with the battery alone (as applicable); make sure it is fully
charged .
• For compliance with EN 50131, the connections to supplementary sirens
(whether self-powered or not, and compliant with the standard) must be pro-
tected with a balanced TAMPER line, using the alarm inputs .
• The relay outputs must be used within the voltage and current limits given in
the figure .
• For compliance with EN5031, conventional detectors connected directly to
the control panel must be EN50131 grade 1 or higher, and operate with
balanced lines, hence resistors must be used as shown (only 3 wires of ade-
quate cross-section) .
• The +OFF signal is positive when the control panel is powered off, and
blocks any detectors/sirens equipped with the appropriate input .
• The fault input, if used, trips FAULT signals and the consequent phone calls
• All unused inputs may be left disconnected (they need not be balanced),
unless they are incidentally closed, even temporarily . In this case the control
panel must be powered off and on again (line reset) .
5.2 - Control panel connections (models HSCU2GC and
HSCU2C only)
Caution! – Before opening the control panel's enclosure, disconnect it
from the mains power supply.
01. To hook up the power cable, insert the ferrite cylinder as shown in fig. 20
and position it as shown in fig. 21;
Warnings:
- To facilitate the connections to the terminal clamps, depress the release
button.
- The wires must be secured by closing the terminal cover with its screw;
02. For the electrical connections to the terminal block, refer to Table 4;
03. To insert the backup battery (not included) refer to fig. 22;
04. Once the connections have been completed, close the internal cover and
only then close the circuit breaker or insert the mains plug .
5.3 - Connections on the HSSOC siren.
To connect the siren with the control panel, refer to Table 4 and figure 27A if
the inputs are set as N .C . or 27B if the inputs are set as balanced .

5.4 - Telephone line connection

Connect the phone line to connector (b) on the control panel, see fig. 6A and
6B on page 11 . * Note (fig. 23 and 24) - The adapters are not included.
In case of other devices connected to the telephone line, follow the order speci-
fied in fig. 23 .
Important! – If an ADSL is used, a special filter must be used (not provided),
which must be installed between the telephone socket and the control panel,
see fig. 24 .
