The Mastercall Door Phone means the end of "no answer" and allows visiting friends, relatives and colleagues to contact you with push button ease from outside when you?re inside or when you?re out and about. The Mastercall Door Phone is ideally suited for all types of domestic and commercial security and communication uses. An easy D.I.Y. installation kit is provided for "plug and play" operation. Knowing that one of the first things that potential intruders will do is to ring the doorbell, why not deter them with an answer? As standard, the Mastercall Door Phone has a relay output to control an electric door strike/latch etc.. Optionally, the Mastercall Door Phone can be ordered with alarm inputs to report alarm events, and with more outputs to activate CCD cameras so that images can be captured on your personal computer. The Door Phone Model MD-4900 looks and sounds like a conventional intercom plate. When you press the button at the front door, you hear a chime coming from the doorplate followed by telephone service tones, eg. ringing tone when the inbuilt telephone dialer is activated and a call is set up to your pre-programmed telephone number. When you receive a call from your Door Phone, it is just like any other telephone call. To end the call, press *9 or just hang up. It is that easy!
