What is a Duet Plus?
The Duet Plus is an indispensable item for any telecom installer. It combines a loud station ringer, night bell, small paging unit and even a low voltage interface – all in one unit. It has an adjustable warble tone, and can be used both indoors and out (with an 8 ohm horn). A Duet Plus with an 8 ohm horn will take care of nearly any application. Strobes or other visual alerters can also be added as accessories.
