DS2 will
work with both Corded and Cordless Phones. A small number of
Older Cordless Telephones may not ring differently as they are designed to
ignore the incoming ring pattern and output their own ring. For this reason,
your unit can be set to output FIVE quick ‘beep’ tones (advice tones)
immediately after answer, to advise you that the incoming call is from your
Door Phone.
OPERATION WITHOUT A TELEPHONE LINE
DS2
will also work WITHOUT connection of a Telephone Line. In this situation,
leave the Line Input port of
DS2
vacant (see the diagram below).
DS2
will ring all attached telephones as normal. This will suit the many users
that no longer use a fixed telephone line. The diagram below shows a wiring
diagram used when a Single Lock Control relay is being used.
