DAA2 & DAX — P/N 53265:A1 8/24/2011 15
Description DAA2 Digital Audio Amplifiers
Charger voltage: 27.6 VDC.
For battery calculation worksheet and standby operating times, refer to Appendix B.1, “DAA2
Battery Calculations”, on page 84.
Utilizes wire sizes 12-18 AWG..
When AC power is lost, the deeply-discharged battery cutoff protection will be invoked at 17
volts. The power supply will be disconnected from the batteries. The power supply’s normal
operation will be restored when AC power returns.
DAA2-5025/70 and DAA2-7525 Boards
 Wire Digital Audio Ports A and B - TB2, TB3
Refer to the Wiring Guide, p/n 52916ADD, for acceptable wire types.
EIA-485 format.
Power-limited and supervised.
Refer to Section 5, “Fiber Option Modules”, on page 75 for fiber connection information.
When a fiber option module is mounted on a DAA2, it disables the corresponding wire
terminals. TB2 (Digital Audio Port A) is disabled when a fiber option board is connected at J9.
TB3 (Digital Audio Port B) is disabled when a fiber option board is connected at J10.
 Alarm Bus - TB4
