9 INSTALLATION AND ACTIVATION OF THE ALARM PANEL
6. Fix the panel to a wall by means of appropriate screws and dowels, using the ports on the box;
the panel must be installed in a closed, ventilated environment, in which there are no dust,
acids, corrosive and/or inflammable gases. The room temperature must be between +4°C and
+4C.
7. Set up the electrical connections as shown in the diagram in Fig. B, making sure that the power
supply voltage is appropriate for the panel (230V±10% 50/60Hz).
8. Connect the faston to the positive pole of the buffer battery
9. Remove any plastic or metal impurity (e.g. copper fragments from the cables, plastic slivers, dust,
etc.) inside the box and power the panel. On the front board the greenLIVE LED switches on;
in this condition the internal buffer battery is automatically kept on charge so that it is always
efficient.
10. Check the correct operation of the panel by pushing the TEST button on the front board.
When one of the two N/O or N/C inputs (4) changes status (i.e. when the N/O contact is closed or the
N/C contact is opened) the alarm is triggered.
The N/O contact is connected to the alarm float that must be located inside the reservoir, while the N/C
contact is kept closed by a bond.
It is possible to set the panel so that the alarm signal turns off automatically when the condition that
triggered the alarm ceases to exist (e.g. when the N/O and N/C inputs go back to normal) or it remains
on even if the alarm condition no longer exists.
In the latter case the turn off may be carried out manually pushing ‘RESET orHORN EXCLUSION on
the front panel board or through the internal trimmer-adjusted timer (8).
With selector (5) engaged the alarm ceases as soon as the alarm conditions cease to exist; if selector
(5) Is disengaged the alarm keeps working until the manual intervention by the operator or of the turn
off timer.
