The Samsung door phone has been discontinued. The small wall mounted door “phone” unit provided voice communications from a remote location, like a locked front door. Pressing the button on the front panel produces a distinctive ring at selected stations. Answering the call allows two-way conversation with the remote station unit. If a relay is installed, a telephone can even unlock the door to allow the guest to enter.
Comtex can provide you with an alternative door phone to connect to your Samsung telephone system. Please contact us.
