Ann-Bus Audio Panel - Honeywell MS-5UD Series Manual

Installation

2.9 ANN-BUS Audio Panel

WARNING! Disconnect all sources of power (AC and DC) before installing or removing any
wiring.
The FACP must be enabled to communicate with the ACC-25/50ZS Audio Panel over the ANN-
BUS (refer to "ANN-BUS Enabled" on page 80). This is accomplished by programming the
Audio Panel ANN-BUS address into the FACP (refer to "BUS Modules" on page 80). For details
on setting the ANN-BUS address and programming the audio panel, refer to the ACC-25/50ZS
Series Audio Panel manual (document #51889).
The ACC-25/50ZS Series audio panel connects to the FACP via the ANN-BUS communication
circuit. The five input zones on the MS-5UD correspond to the first five ACC-25/50ZS Series
audio zones and the ten input zones on the MS-10UD correspond to the first ten ACC-25/50ZS
Series audio zones. The programmer can select which of the five audio messages at the audio panel
will play when an FACP input zone goes into alarm (refer to "ACC Message" on page 63). The
message will play over the corresponding audio panel output circuit. For example, if FACP Input
Zone 3 goes into alarm, the programmed message will play over the ACC-25/50ZS output circuit 3.
If two or more input zones are active at the same time, the highest priority message will turn on.
One of the FACP input zones can be programmed as an All-Call Zone. If this zone goes into alarm,
all ACC-25/50ZS Series audio zones will activate (refer to "ANN-AUDIO Options Screen" on
page 86).
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.
The only connection between the MS-5UD/10UD and the ACC-25/50ZS audio panel is a pair of
communication wires connected between the A/B terminals on TB3 of the FACP and TB1
terminals 2 & 3 of the ACC-ZPMK module on the ACC-25/50ZS.
