2 Operation principle
The microprocessor controller checks the presence of the mains power, battery state, state of
external alarms inputs and a number of internal parameters (e.g. acceptable time of the bulk
charging).
If an improper operation of the device is detected, a fault indication is generated.
This operational state is signalled by corresponding diodes, lighting up in the front panel, and by
three remote indication relays accessible in the back panel. The relays are activated, when no
fault indications are being generated; it means that a fault indication causes deactivation of the
relay.
The power supply circuit is based on a direct floating mode system. The power supply, supplied
from the mains, is connected in parallel with an external battery bank.
The VAS amplifiers supplied with their own power supplies are required not to consume power
from the 24V voltage. However, when power failure, they should automatically switch over to
use the battery power supply.
