OPERATION
After initial Power Up, the Door Phone will take up to 5 seconds to
initialise.
To commence a Door Phone call, you should press the
Rectangular LED lit Perspex button on the Door Phone briefly. The
LED will then turn OFF and you will hear a RING TONE until the
call is answered.
This Door Phone will trigger a Door Station Controller that will
either RING all the telephones connected to your telephone line,
programmed extensions of a PBX system (Digital or VOIP), or it
could Dial Out to an external telephone number (DS Controller
model DS6 only).
As soon as the call is answered, you will be able to communicate
with loud and clear call quality.
Our Door Phones use an intelligent, fast switching ‘half duplex’
communication method, as this provides for highest volume levels
and eliminates feedback. With this method, the party that talks
LOUDEST will take priority and will be connected to the other end.
After your Door Phone call is completed, there will be a delay of
approximately 5 seconds before the unit has reset and is ready for
the next call.
To test your Door Phone:
You will require two people – one to call and one to answer
Do Not
use a telephone in very close proximity of the Door
Phone as feedback will cause loss of volume.
