7.16. Fault Out Connection
Power amplifier panel FV-224PA-AS/ FV-248PA-AS/ FV-248PA-AS 4 F00 can control external equipments
using fault out terminal. FV-224PA-AS/ FV-248PA-AS/ FV-248PA-AS 4 F00 outputs contact when failure
occurs in the unit.

7.17. Power Failure Backup
If broadcasts need to continue even during power failures, power must be supplied from an uninterruptible
power supply system (UPS) or emergency power supply unit.
7.17.1. Providing Backup Power Using an Uninterruptible Power Supply (UPS) System
Using a UPS as a backup power source permits both emergency and general-purpose broadcasts to
continue without interruption even if the main power source fails.
Procure a UPS that meets the following requirements and use it to supply AC power to equipment like the
FV-200PS-AS, FV-224PA-AS, FV-248PA-AS and FV-248PA-AS 4 F00 that must operate continuously even
during power failures. If the UPS does not meet the following requirements, it may shorten the amount of
time that backup power can operate and/or may prevent continued broadcasts. Therefore, it is important that
the UPS selected meets the necessary requirements.

time.
7.17.2. Power Backup Using the VX-2000DS Emergency Power Supply Panel
Using the VX-2000DS as a backup power source permits both emergency and general-purpose broadcasts
to continue without interruption even if the main power source fails. Please refer VX-2000DS manual for
detail about using VX-2000DS as emergency power supply panel.
The method for calculating the battery capacity of the emergency power supply unit needed to ensure
sufficient power backup is described below.
The Storage battery capacity C required to operate for a fixed period of time (T
2 ) after waiting for a fixed
period of time (T ) can be calculated as follows. Select a battery with the capacity larger than the calculation
conversion time K corresponding to Discharge time T, then calculate the required battery capacity using the
equation on below. Also see each unit specification in this manual to determine the current
consumption during standby or operation.
Storage battery capacity C (Ah) = [ K
