DOORPHONE
Definition
A doorphone is a unit that is located at the entrance,
and which is used to call one or more ASB 150 02
extensions.
Use
The doorphone is used to monitor the admission to a
company.
The doorphone function provides also the feature to
open the door lock from an extension.
Calls from the door speaker can be directed to:
• an individual extension (if programmed as hot-
line position of the door-speaker).
• a group of extensions (if programmed as exten-
sions having the possibility to answer the door-
phone calls).
Operation
Operation depends on the type of the doorphone you
are using. The description below refers to the
ERICSSON Door Interface Unit.
Call from door speaker
Depending on the type of the connected door-speaker,
a call is initiated by pressing the doorphone button.
The extension(s) programmed as having the right to
answer the door speaker calls, receive(s) a call signal.
Answering door-speaker calls
The call can be answered from an extension by lifting
the handset and speech connection will be
established.
Opening/closure of the entrance lock
The door opener is activated by making an inquiry to
its directory number. This extension number can also
be programmed on a programmable key.
After making the inquiry the extension that answered
the door-speaker call and made the inquiry to the
door-opener will be automatically disconnected from
door-opener and door-speaker.
At the OPERATOR console the directory number of the
door-opener can be entered on a name selection key.
The OPERATOR console can activate the door-opener
by transferring the incoming doorphone call to the
directory number of the door-opener and the
OPERATOR itself will be free again.
The door-opener will be deactivated after the timeout
interval (possible intervals are 1; 4; 6 or 8 seconds,
adjustable in Door Interface Unit).
Deactivation of the doorphone
Deactivation of the doorphone occurs:
• when the extension which answered the call
goes on hook,
• after an activation of the door-opener,
• after time-out (for security reasons, about 1; 2; or
3 minutes).
Capacity
The number of doorphones is limited only by the
number of available analogue extension positions.
Limitations
The connection of an ERICSSON’s Door Interface Unit
to the ELU-A occupies 2 analog extension positions.
