Door Phones
Door phones are used to call digital/electronic telephones selected in system programming.
When a door phone calls, you hear a distinctive ringing tone, one or five times (set in system
programming). You can also call a door phone and monitor the surrounding area.
The number of possible door phones vary by UST DK system, with up to 12 as the maximum
for larger systems.
LCD telephones display the door phone ID when calls are made to/
from door phones (e.g., door phone 1A). The ID enables you to know
the door phone [DN]. For example, door phone 1A corresponds to
Door Phone [DN]
!$!
, 1B to
!$
, etc. Door phone IDs and the corresponding [DNs] are
shown in Table 24.
