ZAC-30 Zone Amplifier Card
RCM-1 Riser Control Module
The RCM-1 Riser Control module
provides control and supervision of
global paging risers in MXL voice
networks. The RCM-1 is a double-
width card and has 4 ports with the
following inputs and outputs:
PORT STYLE FUNCTION
A 6 Audio signal input
B 4/7 Audio signal input/output
C 4 Audio signal output
D 6 Audio signal output
The RCM-1 supervises Port B for open
and short circuits, reports by exception
to each MXL, and isolates the fault.
Only one RCM-1 may be connected
to
each MXL. The module communi
cates
with the MXL using the RS-485
MNET.
If the RCM-1 detects that communica-
tion is lost with the MXL, it will auto-
matically switch to Local Mode.
ZAC-30 Zone Amplifier Card
The ZAC-30 Zone Amplifier Card is a
30 watt module that plugs into a slot
on the OMM-1/-2 card cage. It super-
vises the audio amplification and its
on-board speaker zone.
The MXLV System controls the input
to the ZAC-30 through the OCC-1 from
one of up to three audio channels. The
amplifier output is switch selectable
for either 25.2V RMS or 70.7V RMS.
The ZAC-30 has one power limited
speaker zone that is controlled by the
MXLV System. The zone may be wired
in either an NFPA Style Y (Class B) or
Style Z (Class A) configuration. The 30
watt output may also be configured as
two 15 watt Style Y (Class B) zones
(split zone).
