Installation DAA Digital Audio Amplifiers
In Riser Mode to Control Modules
When a DAA’s Riser Mode is programmed R
ISER MODE TO CONTROL MODULES (refer to
VeriFireTools help file or the DVC Digital Voice Command manual for programming description),
the amplified signal from the DAA may be routed to multiple speaker circuits using SLC control
modules.
Only one Class A or Class B DAA speaker circuit may be installed when operating in this mode.
Do not use background music in this mode. The DAA will provide speaker circuit supervision only
when idle.
In Riser Mode to RSM/AIM Series Canadian Room Isolator Modules
When a DAA’s Riser Mode is programmed R
ISER MODE TO RSM/AIM SERIES MODULES (refer to
VeriFireTools help file or the DVC Digital Voice Command manual for programming description),
the amplified signal from the DAA is routed to RSM-1A or AIM-1A room isolator modules.
Only one Class A or Class B DAA speaker circuit may be installed when operating in this mode.
AIM-1A - Provides isolation to a separate circuit on an audio riser. A short circuit on an AIM-1A
speaker circuit will not disable other speaker circuits on the riser.
RSM-1A - Works same as the AIM-1A, with the exception that there is a silence button for in-suite
operation. The silence button will silence the audible signal to the module’s circuit for ten minutes
during alarm. Resounding will occur automatically after ten minutes. To override the ten minute
silence, CBE programming must be done at the FACP so that it interrupts the module’s 24VDC
power for two seconds.
NFS2-3030 example:
Give the isolator module’s 24VDC source a common ground with the DAA2 amplifier. Power
the isolator module through a relay module that has Special Zone 14 in its CBE list. Special
Zone 14 will activate for ten seconds when a reset is initiated at the panel.This period is used to
disable the 24VDC for those 10 seconds to clear a local silence.
