Section 3: Primary and Secondary Power for the Audio
Primary power required the for AA-100, and AA-120 Amplifiers are 120 VAC and primary power
required for the AA-100E, and AA-120E are 220/240 VAC. Secondary power (24 VDC battery)
connections must be made at the designated terminals shown in Figure 2.2 and Figure 2.4. Second-
ary power may be obtained from any source of 24 VDC which is Listed for Fire Alarm Signaling
and has sufficient alarm and standby capacity (CHG-120). Use Table 3.1, Table 3.2 and Table 3.3
to calculate amplifier secondary (battery) power requirements.
NOTE: AC POWER MUST BE CONNECTED TO THE SAME CIRCUIT AS THE 7100 SERIES
CONTROL PANEL.
