Engineer and Architect Specifications
ASC-1
Supervision of primary and backup amplifiers shall be
provided by a configurable plug-in module, model ASC-
1. The card shall plug into one slot in on the OMM-1
MXLV cardcage. Multiple ASC-1s may be used to
supervise additional amplifiers, both primary and
backup, as necessary. Through the use of the ASC-1,
backup amplification shall be provided on either a one
for one or one for multiple basis. Backup amplifiers shall
be capable of supporting primary amplifiers in any of 3
channels.
The amplifier supervisory card shall monitor the input
and output of each amplifier and check for proper audio
level. If a primary amplifier output is found to be defec-
tive, the supervisory card shall annunciate a system
fault condition and transfer operation to the backup
amplifier if supplied. The backup amplifier shall replace
the first failed primary amplifier.
The ASC-1 card edge fingers shall be gold plated for
highest reliability. The module shall be provided with a
key which when inserted into the OMM-1 card slot will
prevent any other type of module from being inadvert-
ently plugged into that slot.
The ASC-1 shall occupy one of the OCC-1 module sub-
addresses. This address shall be set using an on-board
DIP switch. A second dip switch shall be provided to
configure the ASC-1 operation.
ASC-2
Supervision of primary and backup amplifiers shall be
provided by a configurable plug-in module, model ASC-
2. The card shall plug into one slot in on the OMM-1
MXLV cardcage. It shall be capable of supervising one
primary and optionally, one backup amplifier. The ASC-
2 shall be used to supervise high power audio risers
when ICP remote control modules are controlling audio
zones. Multiple ASC-2's may be used to supervise
additional amplifiers, both primary and backup, as
necessary. Through the use of the ASC-2, backup
amplification shall be provided on either a one for one
or one for multiple basis.
The amplifier supervisory card shall monitor the input
and output of each amplifier and check for proper audio
level. If a primary amplifier output is found to be defec-
tive, the supervisory card shall annunciate a system
fault condition and transfer operation to the backup
amplifier if supplied. It shall also initiate a system
trouble condition regardless of whether or not a backup
amplifier is supplied.
The ASC-2 card edge fingers shall be gold plated for
highest reliability. The module shall be provided with a
key which when inserted into the OMM-1 card slot will
prevent any other type of module from being inadvert-
ently plugged into that slot.
The ASC-2 shall occupy one of the OCC-1 module sub-
addresses. This address shall be set using an on-board
DIP switch. A second dip switch shall be provided to
configure the ASC-2 operation.
