Door Phone - Toshiba Strata DK14 General Description Manual

Door Phone

The optional door phone/monitor station is an external/remote two-way speaker box which has a
direct voice link to a station. A door phone is frequently mounted near a building entrance and
associated with a customer-provided door lock to help screen visitors. Pressing the button on a
door phone sends a distinctive ringing only to idle digital or electronic stations which have been
programmed to receive ringing from that door phone.
If all stations are busy, a muted ring is sent to the lowest numbered station programmed to ring.
When a station answers, it is automatically connected to the door phone. Door phones can be
programmed to ring over external page when the system is in Night mode.
A station can dial an individual door phone/monitor station and either converse with someone at
the door phone, or simply monitor conversation or sound at the door phone. No warning tone is
heard at the door phone/monitor station when it is called by a station.
Door phones are supported by the door phone/lock control box (DDCB) external module. One
control box supports up to three door phones. The DDCB requires one DKT station circuit on a
PDKU, RDSU, KCDU, or QCDU.
Door phones can be assigned to ring PDNs and/or PhDNs. The number of door phones is each
system supports is:
DK14 – up to six door phones
DK40i – up to nine door phones
DK424 – up to nine door phones with RCTUA, and up to twelve door phones with all other
processors
Benefits

line" calling link between an office and such facilities as a warehouse or laboratory.
