3.2. About the Emergency Power Supply
3.2.1. Selection of the emergency power supply panel and battery
The emergency PA system is designed to operate on both the main power supply and emergency power
supply. Because the emergency system needs to be operated for ten minutes or more during a power failure,
the emergency power supply suited to the system scale is required. The FS-970 series systems require the
emergency power supply panel DS-029B and Ni-Cd battery NDC-2435 or NDC-2460. The following table
provides guidelines on the number of emergency power supply panels and Ni-Cd batteries necessary for the
system.

Notes
• This table assumes that the main rack system and emergency remote control unit are identical in the
number of broadcast zones. It is also assumed that no other components are connected other than the EP-
029, EP-0510, EP-059R, JP-039, and JP-0410, and that any component is not connected to the emergency
power-off output or emergency output. In some systems, the number of zones may be less than those
shown in the above table.
• Refer to the connection examples on p. 27-30 for connection methods a-d of the Emergency Power Supply
Panel DS-029B.
3.2.2. DC power supply panel expansion
When multiple operation sections or emergency remote control units are connected to the main rack, the DC
power supply panel is required in addition to the Emergency Power Supply Panel DS-029B. For its
connection, refer to "DC Power Supply Panel Connection" on p. 34.

Note
Depending upon the connection method of the JP-0410's internal power supply/ expansion power supply to
expansion equipment (EP-029, EP-059R, JP-039, etc.), the number of zones may lower those shown in the
above table. When using other combinations not shown in the table, contact the shop from where you
purchased the unit.
Expansion power supply is required.
