1825 Duet Plus ® Auxiliary
Ringer |
|  The
1825 Duet Plus ® auxiliary ringer is a multi-application
loud ringer and paging amplifier for use with business telephone
systems in office/industrial applications.
The 1825 Duet Plus® ringer is specifically designed for
compatibility with Nortel Networks™ systems, including
Meridian 1, Norstar, and BCM. System connectivity is possible
for loud ringing and/or small paging applications. Station
connectivity is possible for all telephones whether analog
or digital. Application notes are available to describe functionality
with M2000, M3900, M7000, and T7000 terminals. Available as
1825P with power supply and modular cord |

Optional
1185 Horn Speaker |
Non Irritating Tone Output
Warble tone output is specifically designed to be non-irritating
even at loudest volumes and more effective than shrill piezo
type ringers in alerting personnel with hearing impairments,
wearing ear protection, or in high ambient noise environments.
These advantages are achieved by using a lower frequency range
than most electronic ringers.
Optional 1185 Horn Speaker
The 1825 Duet Plus ® contains a speaker for low to moderate
noise environments such as offices, storage areas, warehouses,
and lunch rooms. For higher ambient noise or outdoor environments
such as machine shops or work yards, the 1185 horn speaker
can be added to achieve one of the most effective and weatherproof
industrial loud ringers available. The economical and robust
1185 horn speaker is driven by a power amplifier in Duet Plus
® .

 Alternatively
to the warble output, Algo also offers a programmable version of its traditional
ringer, the 1826 Talking Duet Plus. Instead of producing a warble signal,
the Talking Duet Plus produces an audio signal that is recorded into memory
and then played back when triggered. Messages may be voice, music or sound
effects from 0.1 to 16 seconds in length.
An additional feature of the Talking Duet Plus is
the ability to store and release page messages for feedback elimination.
