In Riser Mode to Room Isolators (CIM or CSM Series) - Canadian Room Isolator
Modules
When a DAX’s Speaker Riser Mode is programmed R
OOM ISOLATORS (CIM OR CSM SERIES)
(Refer to the DVC Digital Voice Command manual for programming), the amplified signal from
the DAX is routed to a CIM-2A module, which feeds the signal to one or two CSM-1A modules.
A pre-announce tone of 800 Hz will clear a local silence.
Do not use background music in this mode. The DAX will provide speaker circuit supervision only
when idle.
Speaker Backup Circuits - TB10 and TB 11
The DAX supports one-to-one or one-to-many backup amplification. A BDA-25/70V backup
amplifier may be used in a one-to-one backup application. Each DAX must be designated a primary
or backup amplifier through VeriFire Tools programming. The speaker wiring from backup to
primary is unsupervised when the backup amplifier is not active; therefore the backup and primary
amplifiers must be in the same enclosure, or in conduit within the same room.
NOTE: The DAX-3570 and DAX-5070 speaker circuit risers are non power-limited when used
with Canadian room isolator modules.
DAX-3525 and DAX-5025 speaker circuit risers are power-limited when used with Canadian room
isolator modules.
