Inter-tel 3000 Door Phone
With a door phone installed in your reception
area, anyone visiting your premises can call when they arrive and you can speak
to them before you let them in.
If you want to use a door strike relay you must
purchase the door strike mechanism your self and arrange for a qualified
electrician to install it.
The door phone has a button for ringing
programmed extensions, a microphone and speaker for communication and two way
conversations. |
