Field Programming
2.4.2 S2 and S3 Addressing Rotary Switches
Two addressing switches are located at the bottom right of the ACC-ZPM Zone Page Module. The
switches are used to set the EIA-485 address of the ACC-ZPM to allow communication between it
and the ACC-25/50ZS/T. This communication link allows the ACC-25/50ZS/T to control the
speaker circuits.
To set the address, use a small nonconductive flat-blade screw driver to turn the switch dial so the
arrow points to the correct address number. The factory default setting is S3 =
0
and S2 =
1
. The
following illustration shows the switches set for address
01
with S3 (Tens) set to 0 and S2 (Ones)
set to 1.
ACC-ZPM Addressing for Style Y (Class B) Audio Circuits
The ACC-ZPMK, which is located in the main ACC-25/50ZS/T Audio Panel, is set to address
01
(as illustrated in Figure 2.3) for communication with the FACP via the ACS link and will control
Style Y (Class B) Audio Zones 1-8. The ACC-ZPM modules located in the ACC-25/50DAZS
Distributed Audio Panels connected to the ACC-25/50ZS/T Audio Panel, must be set to consecu-
tive addresses, starting with address 01, and will control Style Y (Class B) Audio Zones 9-16 and
17-24 as detailed in the following table.
ACC-ZPM Addressing for Style Z (Class A) Audio Circuits
The ACC-ZPMK, which is located in the main ACC-25/50ZS/T Audio Panel, is set to address
01
(as illustrated in Figure 2.3) for communication with the FACP via the ACS link and will control
Style Z (Class A) Audio Zones 1 - 4. The ACC-ZPM modules located in the ACC-25/50DAZS
Distributed Audio Panels connected to the ACC-25/50ZS/T Audio Panel, must be set to consecu-
tive addresses, starting with address 01, and will control Style Z (Class A) Audio Zones 5-8, 9-12,
13-16, 17-20 and 21-24 as detailed in the following table.
