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 NFV-25/50ZS/T 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 NFV-25/50ZS/T Series audio zones will activate (refer to"ANN-AUDIO Options Screen" on
page 87).
A fault at the NFV-25/50ZS/T 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 SFP-5UD/10UD and the NFV-25/50ZS/T audio panel is a pair of
communication wires connected between the A/B terminals on TB3 of the FACP and TB1 termi-
nals 2 & 3 of the ACC-ZPMK module on the NFV-25/50ZS/T.
