4.1. Power supply for the alarm center (full range 90 and 265 Vac)
Alarm unit is equipped with a full range switching source that works with the input
voltage of 90 and 265 Vac without the need of a voltage selector switch. This way,
even if some voltage variation occurs in the mains, the alarm unit will continue
working normally (as long as the voltage is in the range of 90 to 265 Vac).
On this board there are two protection fuses of the unit. If you need to change, use
new ones of the same value (250 V/400 mA).
To connect the AC mains input and also to ground, it is recommended to use a
three pin cable with a gauge of 1 mm or higher.
The output to the alarm center board is 5.7 Vdc and 1.7 A.

XFT 8000 Power Supply
Connect the source ground terminal as shown above to the local electrical
installation ground.
If the local electrical installation is not grounded, install a grounding bar and wire
the connection terminal to the alarm center to perform the correct grounding.
Attention: it is mandatory to connect the grounding to the alarm center in order
to have greater protection against lightning and overload by the mains and/
or telephone line. If this connection is not made, the alarm center will function
normally, but will be unprotected against overloads.
Warranty does not cover possible damages caused by lightning to the alarm center
or to any other equipment connected to it.
