Algo 1825PM Duet Plus Analog Loud Ringer & Paging Amplifier

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. Additionally, the Algo 1825PM Duet Plus can provide amplified voice paging as a separate application or in combination with loud ringing utilizing the same speaker.
