1.2 DESCRIPTION
The CFA Door Phone is consists of two main stainless steel / zincalume components:
1. The Front Door Plate
This is a vandal resistant stainless steel plate (2 mm thick). It contains the weather resistant
push button, microphone and speaker.
2. The Inside Hide-away Unit
This is the control unit containing all the electronics, programmed data, auto-answer setting, and
dialer. There are connectors for the front door plate, the telephone line, switched transistor
output for a door/gate latch and optional power for when line power is insufficient. Optional
sockets are available for another switched relay output, an external alarm input, and an RS232C
serial port.
The front door plate and the inside hide-away unit are simply connected to each other using the
eight-wire cable provided (longer cables up to 30 meters to order). The inside hide-away unit is
connected to any working telephone socket (pins 2 & 6 on a 610 socket or centre pins 3 & 4 on
an RJ12 jack). RJ style plugs are provided.
The MD-4931CFA is telephone line powered so the unit continues to operate in the event of
mains power failure.
