B
UZZER
The status and the faults of the UPS are signalled by the buzzer, which will emit a sound according to the various operating
conditions of the UPS.
The various kinds of sounds are described below:
Sound A:
This signal is emitted when the UPS is turned on or off using the apposite buttons. A single beep confirms the start-
up, the activation of the battery test, and the cancellation of the programmed switch-off. By keeping the power-off
button pressed, the buzzer will emit in rapid succession sound A four times, before confirming the switch-off with a
fifth beep.
Sound B:
This signal is made when the UPS commutates to bypass in order to compensate the surge current due to the
insertion of a distorting load.
Sound C:
This signal is emitted when the UPS switches to battery operation, before the low battery signal (sound D). It is
possible to silence the signal (see the “Graphic display” paragraph).
Sound D:
This signal is made during battery operation, when the low battery threshold is reached. It is possible to silence the
signal (see the “Graphic display” paragraph).
Sound E:
This signal is emitted in the presence of an alarm or lock.
Sound F:
This signal is emitted if a battery overvoltage fault occurs
Sound G:
This signal is made when the battery test fails. The buzzer beeps ten times. The alarm signal is maintained with the
“replace batteries” LEDs on.
