If an entrance telephone has been programmed, you can use your telephone to speak to someone at the entrance telephone and to activate a door opener.
If you are authorized to activate a door opener (contact System Support), visitors can open the door themselves by entering a 5-digit code (using a DTMF transmitter or installed keypad).
