The Algo 1825PM Duet Plus is an analog loud ringer with paging amplifier that can be wall mounted in office, home business, or quiet warehouse locations utilizing its built in amplifier and speaker to generate up to 93 dBA (at 1M) warble tones. By adding the optional Algo 1186 Loudspeaker (not included) output can be increased up to 112 dBA (at 1M). The combination of lower frequency warble and high sound pressure level creates an extremely effective and pleasant telephone alert where additional ring volume is required.

For small business applications this provides an extremely cost effective and high performance solution for loud ringing and loud paging into a warehouse, storage yard, or machine shop. Separate volume control is provided for voice page and loud ring levels. Other features include adjustable warble frequency, adjustable volume, and integrated test button. Includes 24V power supply.
