UDIBLE SIGNALLING DEVICE
The status and anomalies of the UPS are signalled by the buzzer, which emits a modulated sound depending on the
various UPS operating conditions.
The various types of sound are described below:
Sound A:
The signal is emitted when the UPS is switched on or off using the appropriate buttons. A single beep
confirms power-on, the activation of the battery test, the cancellation of programmed power-off. Holding
down the power-off button causes the buzzer to emit sound A four times in rapid succession, before
confirming power-off with a fifth beep.
Sound B:
The signal is emitted when the UPS switches to the bypass in order to compensate for the surge current due
to the activation of a distorting load.
Sound C:
The signal is emitted when the UPS switches to battery operation before the battery low signal (sound D). It
is possible to silence the signal (see "Graphic display" paragraph)
Sound D:
The signal is emitted when, during battery operation, the battery low alarm threshold is reached. It is
possible to silence the signal (see "Graphic display" paragraph)
Sound E:
The signal is emitted in the presence of an alarm or lock
Sound F:
The signal is emitted in the presence of the battery overvoltage anomaly
Sound G:
This type of signal is emitted when the battery test fails. The buzzer emits ten beeps. The alarm signal
remains and the "replace battery" LED lights up.
