CFA DOOR PHONE
MD-4931CFA
SPLIT-SYSTEM HANDS-FREE DOOR TELEPHONE
1. INTRODUCTION
The CFA Door Phone, with a line powered inbuilt telephone dialer and hands-free speaker
phone, automatically connects people at unattended CFA station doors or gates directly to
Officers on their PABX extension, mobile phone, or any other telephone at manned stations.
This system is made for emergency services agencies that are security conscious and want things
made simple and easy. The door unit is robust yet slim.
The CFA Door Phone means the end of ‘no answer’ and allows members of the public and
colleagues to contact you with push button ease from outside when you’re inside or when you’re
out and about.
The CFA Door Phone is ideally suited for all types of emergency services security and
communication uses. Easy installation makes for ‘plug and play’ operation.
As standard, the CFA Door Phone has a relay output to control an electric door strike/latch etc..
Optionally, the CFA 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.
Things that make this unit unique are its strength, slim style, performance and compatibility with
any phone system analogue extension. All electronic circuitry is safely tucked away inside in the
hide-away unit so that replacement of the doorplate is inexpensive, should this ever be
necessary.
Pride has been taken in the making of this unit, with as much emphasis placed on the electronic
design as there was with the superb appearance.
1.1 OVERVIEW
The CFA Door Phone Model MD-4931CFA looks and sounds similar to a conventional intercom
plate. When you press the button at the front door, you hear dialing tones 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 for instant disconnect or just hang up. It is that easy!
