Installation Guide
KAR4120PSWE/KAR4150PSWE ATTENUATOR
The KAR4120PSWE and KAR4150PSWE are 100V
line volume controls which attenuate the sound in 12
smooth steps. All steps are 3dB except for the last 2
which are 6 dB each giving better control at the lower
end. There is no stop position allowing selection from
full volume to off in one step. A 24V DC input activates
a relay, which overrides the volume control for
emergency announcements.
The design is simple and ergonomic fitting in with any
décor. The units can be flush or surface mounted in one
of the standard enclosures.
