8. On-Off indicator.
This indicator shows the presence of power
supply for the control unit, either from mains or from the
optional battery backup system.
9. Fault indicator.
This indicator shows the presence of a fault in
a remote sensor or in the wiring to the control unit. Refer to
proper section for explanation of the possible causes of fault.

[x] INSTALLATION, ELECTRICAL WIRING
──────────────────────────────────────────────────────────────────────────────────────────────────────
WARNING
This unit is NOT approved for the installation in ATEX classified zones.
The wires towards the remote sensors must have a minimum section of 1,5 mm² and max. length 25 m. Do not use the same
pipe for signal and power supply wires.
If the installation is set in environments with strong EMC interferences, it is strongly recommended to use shielded wires. They
have to be connected to the ‘Gnd’ clamp only on the control unit side.
The unit control and/or the power supply, if powered at 230V, must be connected to mains grid through a switch able to
disconnect both of the poles, complying with the current safety standards, and with a separation of at least 3 mm in each pole.
The installation and the electrical wirings of this device must be performed by qualified technicians and complying with the
current technical and safety standards.
Before performing the electrical wiring on the unit make sure to turn mains power off.
It is installer’s duty (whose responsibility is to set up a detection system compliant with existing standards, both national and
European) to choose the appropriate types of loads to be connected to the control unit and to correctly configure the system
parameters. In case of doubt, contact the distributor.
The unit is normally powered with mains power voltage through the terminals 3 and 4 or alternatively at 12-24Vdc through the terminals 7
and 8.
It is possible to connect a backup system with a battery, which aim is to guarantee the full functionality of the unit even in case of lack of
power (see section [p] for details).
The unit is featured with five relays with voltage-free changeover contacts (SPDT): 2 auxiliary relays (AUX1 and AUX2), 1 pre-alarm relay
(PREALARM), 1 relay for alarm 1 (ALARM1) and 1 relay for alarm 2 (ALARM2).
The outputs AUX1 and AUX2 can be used to drive generic load such as an air extractor.
Generally, the pre-alarm output is used to connect a siren, while the alarm outputs are used to connect a solenoid gas valve.
The outputs for the management of anomalous conditions, terminals 13 to 27, are voltage free and insulated with reinforced insulation
towards the other circuits of the control unit. Therefore, a control unit can be supplied with SELV low voltage (12V
.. 24V
), and, at the
same time, control high voltage loads (230V
), as shown in Fig. 5.
In this case, 12V
.. 24V
SELV and 230V
cables must be separated in accordance with current standards.
In particular, it is necessary to secure the two groups of cables with cable ties separating the SELV wires from the others. This is required
to avoid that the insulation to SELV is reduced in the event of a wire accidentally disconnects.
2 or 4 or 8 transmitters (according to the product version) can be connected to the control unit; they have to be compatible with the
4..20 mA current loop system.
For the electrical wirings see the electrical diagrams.
It should be noted that all the outputs of the control unit are voltage-free, so they do not supply power to the loads, giving the
user greater freedom to use loads with different operating voltages.
