The Algo 1825PM Duet Plus is a high
performance low-frequency loud ringer for high noise / wide area
environments where telephone ringing is difficult to hear (e.g. factory,
machine shop, warehouse, lunch room). The Duet Plus can also help to
avoid missed calls due to a hearing impairment. The device interfaces to
a CO line or with any telephone system via an analog FXS port, ATA or
contact closure such as a night bell.
Loud ringing can be activated by a relay or switch closure (dry
contacts), low voltage detection, 90V analog telephone ringing, or the
headset jack on selected Nortel Norstar and BCM digital business
telephones.
