ALGO 1825PM Multi-Application Loud Ringer and Paging Amplifier

The Algo 1825 Duet Plus is a high performance low-frequency loud ringer compatible with most business telephone systems in office and industrial applications. The unit is compatible with dry contact closure, analog telephones, and Nortel digital telephones including Norstar, Business Communication Manager (BCM), Meridian 1, and Communication Server 1000 (CS 1000).

Loud ringing can be activated by a relay or switch closure (dry contacts), low voltage detection, 90V analog telephone ringing, or any Nortel TDM digital business telephone. Non-Irritating Tone Output The 1825 Duet Plus can be wall mounted in office or quiet warehouse applications utilizing its built in speaker to generate up to 93 dBA (at 1m) warble tones. An optional 1185 Horn Speaker is available for very loud or outdoor requirements (112 dBA at 1m). The combination of lower frequency warble and high sound pressure level creates an extremely effective and pleasant telephone alert for large or noisy locations. Amplified Voice Paging An additional feature of the 1825 Duet Plus is its capability to provide amplified voice paging as a separate application or in combination with loud ringing utilizing the same speaker. For small business telephone systems 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 useful features include adjustable warble frequency, adjustable volume, and integrated test button. Compatibility Application notes are available to describe functionality and any additional product requirements for various applications with the following series of Nortel digital telephones: M7000, T7000, M2000, M3900 and M5000; and analog telephones.
