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 BELL 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 or it will operate
with a PABX system.
As soon as the call is answered, you will be able to communicate with
loud and clear call quality.
If this Door Phone is connected to a Model DS6 Controller, you will also
have the ability to connect to an external telephone number, or cell
phone whenever the site is unattended.
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.
For maximum clarity, it may be necessary to adjust the Balance
Pot (see page 9).
WHEN TESTING YOUR DOOR PHONE
DO NOT USE A TELEPHONE IN CLOSE PROXIMITY
AS FEEDBACK WILL CAUSE LOSS OF VOLUME.
