Hi all,

I'm looking for a (good) supplier for a basic door entry phine thing.

Google shows up loads of stuff but I'm really asking if someone here
has personal experience of such and can advise please.

I need to add another handset to an existing pair and upon inspection
it seems like they have the basic connections inside like a std
telephone (screw terminals marked 1-6) and the orig installer has
tacked a (PTM) button on the top for the door release cct?

All the best ..
