Using
a
Doorphone
If you have a doorphone, your
BT
engineer
must program and enable the doorphone.
If
you have a doorphone, anyone visiting your
premises can call you when they arrive, so
you can speak to them before you let them in.
If you have a doorstrike fitted, you can open
the door from your phone by using a feature
code.
Your BT engineer can provide the connection
for a doorstrike but you must purchase the
doorstrike yourself, and arrange for a
qualified electrician to install it .
