Features and Specifications Manual
The Xen IPK system supports up to four Door/Monitor telephones. A
Doorphone can be called by a station or a station (or number of stations)
can be signalled when a Doorphone call button is pressed. When a station
answers the Doorphone ringing, a two-way speech path is established.
In addition to the Doorphone ringing assignment, both the tone and
cadence of Doorphone ringing can be defined. This offers an easy way for
the station user to distinguish a Doorphone call from any other type of call.
The Door/Monitor Telephone works closely with the Door Lock Release
feature, and the DPH(4)-U( ) ETU that supports both features.
