Automatic Audio Panel Control

2.9.4 ECC-FFT Firefighter Telephone
The ECC-FFT connects from TB1 (non-resettable aux power) on the FACP to the DC Power input
on the ECC-FFT board.

2.10 Automatic Audio Panel Control
The FACP annunciator bus serves as the "FACP Data Bus" to the ECC-50/100 or ACC-25/50 audio
system. User programming is required to set up the operation of the audio system. To set up the
annunciator bus, refer to Section 2.9.2 on page 42. The annunciator protocol, ANN-Bus or legacy
ACS-Bus, must be selected and enabled. Note that only one of the protocols may be enabled in the
system. Refer to "Guidelines" on page 22 for conditions when using the ANN-Bus.
When using the ACS-Bus protocol, ACS address 01 must be enabled in the FACP programming.
When using the ANN-Bus protocol, the FACP will automatically detect the audio system connec-
tion during annunciator "auto-configuration". No ANN-Bus address selection is necessary at the
FACP.
Once the FACP can communicate with the audio system, FACP zones Z33 through Z56 become
automatically dedicated as output zones for speaker circuits 1 through 24 respectively. FACP zone
Z32 is dedicated to turn on all speaker circuits. FACP programming allows association between
any addressable SLC input device (module, detectors) with any of the speaker circuits. In addition
1 of 14 messages (1 of 5 using the legacy ACC panel) can be generated over the selected speaker
circuit. Any fault in the ECC-50/100 audio system is sent to the FACP via the FACP Data Bus and
is indicated as an annunciator fault on the FACP display. A fault at the ACC-25/50ZS Series panel
will cause the FACP to indicate a System Trouble and the display will indicate a Voice Evac Fault.
For speaker circuit mapping and audio message assignment, refer to "Zone Message" on page 90.
Also, refer to "Programmed Activation by FACP" in chapter 3 of the ECC-50/100 Instruction Man-
ual (Doc. LS10001-000FL-E) or Appendix D, "Programmed Activation by FACP" in the ACC-
25/50ZS Series Instruction Manual (Doc. 51889).
