MS-5UD-3/7 and MS-10UD-3/7
Programmed Activation by FACP
D.4 MS-5UD-3/7 and MS-10UD-3/7
The ACC-25/50ZS and ACC-25/50ZST can be automatically triggered via the ANN-BUS serial
link by the MS-5UD-3/7 or MS-10UD-3/7 (version 2 or higher), to transmit one of five messages
over selected speaker circuits. This is accomplished by zone programming at the FACP.
D.4.1 Overview
The ACC-25/50ZS and ACC-25/50ZST provide 8 speaker circuits standard via the ACC-ZSM
Zone Splitter Module. Expansion to 24 speaker circuits is possible by adding ACC-25/50DAZS
panels. The ACC-25/50ZS and ACC-25/50ZST also have the ability to generate and direct one of
five messages to specific speaker circuits.
The FACPs communicate with the ACC-25/50ZS and ACC-25/50ZST over the ANN-BUS termi-
nals using the ANN-BUS protocol only.
When configuring the ACC-25/50ZS/T for use on the ANN-BUS serial link, the ACC-ZPMK’s
address wheels can be set to any address between 1 through 8 and enabled in the FACP program-
ming. When this option is enabled, FACP input zones 1 through 5 on the five zone panel corre-
spond to speaker circuits 1 through 5 on the ACC-25/50ZS/T and 1 through 10 on the ten zone
panel correspond to speaker circuits 1 through 10 on the ACC-25/50ZS/T respectively. One of the
input zones can be programmed to be an All-Call Zone, which will activate all speaker circuits.
Any one of the five messages can be assigned to any of the input zones.
All faults on the ACC-25/50ZS and ACC-25/50ZST are sent upstream via the ANN-BUS link and
are indicated as a
Voice EVAC Fault
on the display.
Important Notes:
1. For proper operation, a message must be assigned to each zone that is programmed to activate
an audio speaker circuit.
2. The message repeat setting on the ACC-25/50ZS and ACC-25/50ZST should be set to infinite.
This will ensure that lower priority activated zones will continue to broadcast the voice
message.
3. CMD inputs are not used for activation of the ACC-25/50ZS and ACC-25/50ZST, however,
4.7K
ELRs must still be connected across CMD3, CMD4, and CMD5.
4. Annunciation of remote FFT (FireFighter Telephone) locations is not possible.
D.4.2 Basic ANN-BUS Step-By-Step Install/Setup
1. Connect ANN-BUS wiring from FACP to ACC-25/50ZS or ACC-25/50ZST.
2. Set Address Wheels on ACC-ZPMK to any address from
01 through 08.
3. Set DIP Switches (1 = ON, 2 = ON, and 3 = OFF) on Switch S1 of the ACC-ZPMK for
operation with the FACP and switches 6, 7 and 8 for the number of ACC-25/50DAZS panels.
4. Set Switch SW1 on the ACC-ZSM for one or two Audio Amplifier (ACC-AAM25)
configuration.
5. Set Switch SW2 on the ACC-ZSM for Style Y (Class B) or Style Z (Class A) speaker circuit
wiring.
6. Set DIP switches 1, 2. and 3 on Switch S3 of the ACC-25/50ZS or ACC-25/50ZST
motherboard for Single Zone with activation of 2-5 messages.
7. Record any new messages into the ACC-25/50ZS or ACC-25/50ZST.
8. Enable ANN-BUS communication, Auto-configure the ANN-BUS, assign messages (1-5) to
input zones and assign All-Call zone (if desired) on the FACP.
