Door Phone
What’s this?
Door phone is very similar to ordinary phone except that it does not have a hook-switch and dialing keypad.
Instead, it normally has a key to be used as doorbell. Doorphone is installed in place of Doorbell. It is very
useful accessory with a PBX in flats, bungalows, offices, etc.
Vision offers a facility to program Doorphone port as normal station.
How it works?
• When a visitor arrives at the house and presses the door phone key, the PBX senses the doorbell and starts
special triple ring on the stations of door phone group. The LED on the doorphone flickers.
• The station user inside the house hears the ring. The ring cadence is different which helps to the station
user to identify it as door phone call.
• The station user answer the call. The LED on the key of Door Phone turns steady ON.
• The Door Phone circuit is activated and two-way speech is established between the visitor and the station
that answered the call.
• The owner verifies identity of the visitor by speaking to him.
• He goes to open the door. If door-lock is installed, the owner can open the lock by dialing a code.
•
The owner can speak to the Door Phone even when there is no ring by dialing 3996 after lifting the
handset.
