Description
The SCA and DCA ampliers are a new addition to the Potter
proprietary P-Link device catalog. Potter oers seven variations of
ampliers with wattages up to 100W to support small, medium, and
hi-rise applications. The ampliers have the capability to distribute up
to two audio channels simultaneously across multiple speaker zones.
Each amplier is supplied with a stacker terminal block to provide
accommodations for 8 Class B or 8 Class A speaker outputs. The SCA
and DCA ampliers oer output power at 25VRMS and 70VRMS.
Up to 31 ampliers can be linked to the IPA-4000V panel and oer up
to 248 Class B or Class A speaker outputs.
The DCA-10025 (Dual Channel, 100W, 25VRMS Amplier) may
be programmed to provide an extraordinary 200W for single channel
applications via Potter Fire Panel Programmer.
The 70V-1000 converter module will extend output power to 70VRMS
on the DCA dual channel ampliers. The BUA-1000 backup amplier
provides a failsafe solutions for potential lapse in service and
compatible with the DCA dual channel ampliers.
