1825PM Duet Plus

1825PM Duet Plus

The 1825PM Duet Plus is designed primarily as an analog loud ringer for high noise/wide area environments where it is difficult to hear telephone ringing (e.g. garage, warehouse, factory). The Duet can also help to avoid missed calls due to a hearing impairment. The Duet features a non-irritating low frequency warble tone output that is pleasant to hear, but effective as a loud ringer. The device features an RJ11 jack for connection to an analog FXS port on any telephone system, ATA, or alternatively to a CO line. The Duet can also activate via dry contact closure (e.g night bell). On selected Nortel Norstar and BCM digital telephones the headset jack can be used for a convenient interface. For high noise environments or outdoor applications (e.g. yard, car lot, farm), the 1186 Horn Speaker can be added to boost volume of the Duet Plus. For smaller voice paging applications, the Duet features an Audio Input for connection to any page port on a PBX or key system. On an Avaya IPO the Duet may be connected directly to an FXS port for “wet” paging. A 24V power supply is included with the product.
