Product Description Specifications
Backup Audio In - TB2, Terminals 1(+) & 2(-) [Out Terminals 3(+) & 4(-)] on Amplifier
Module
Operation: When TB2 is wired between the two amplifiers of a panel, the optional amplifier pro-
vides backup to the standard amplifier. Switch S1 on the backup amplifier must be 'ON' and jump-
ers placed from backup amplifier TB2 Terminal 3 to standard amplifier TB2 Terminal 1 and from
backup amplifier TB2 Terminal 4 to standard amplifier TB2 Terminal 2. Refer to Section “One
Speaker Circuit With Backup” on page 62, for additional information.

ACC-ZSM Zone Splitter Module and ACC-ZPM Zone Page Module
Power-limited circuitry
Operation: Circuits on ACC-ZSM can be wired as eight Style Y or four Style Z
Normal Operating Voltage for Speaker Circuits: 25 V
RMS
@1 amp Max. and maximum Load
Impedance of 25 
(70.0 V
RMS
@ 350 mA max. with maximum Load Impedance of 200 operation possible
by plugging optional FC-XRM70 conversion module into P1 of audio amplifier).
Speaker circuit wiring is supervised during standby and alarm. (Note that background music is not
permitted in Zone Splitter configuration since open-circuit fault detection is not possible.)
Output Power: 25 watts total.
Frequency Range: 800Hz - 2,800Hz
Maximum total capacitance for ACC-AAM25: 250 µF. (Note that the total capacitance for the
ACC-ZSM speaker outputs must not exceed the maximum of 250 µF.)
End-of-Line Resistor required for Style Y (Class B) speaker circuit: 4.75 K , 1 watt (P/N: 75470)
TB1 on ACC-ZPM: ACS (EIA-485) electrically isolated link to FACP provides programmed
