Hi
Our flat door entry phone handset is old, yellow and bit tatty.
Can I replace that with any new door entry phone-or does it have to be of the same make and model of the outdoor unit at main entrance to property?

No you can generally fit a universal model to replace the one you have. I fitted this one a while back to replace an old one: https://doorentrydirect.com/comelit-universal-door-entry-phone-with-2-buttons-mini-series

Fairly easy to fit - the only issue is figuring out which wire connects where (there will be 5 wires for a simple system with one button to unlock the door). My old one had the following wiring:

1 - Call button
R - Microphone
O - Common
T - Speaker
Z - Lock Release

While the new one has:
A - Lock Release
B - Microphone
C - Common
D - Call button
E - Speaker
