does this have a door release button?

Yes, the grey Button on the picture is the door release button

is this compatible with an old Targha system?

Yes, it is a very simple thing, just connect the wires. Only issue is working out which wires. Any electrician could do this, or any telephone engineer. You just need a multimeter in fact. Age of system makes no difference. Hope this helps.

The buzzer is very low even though we upped the potentiometer. Any thoughts on what the issue may be?

Sorry I can't help you my handset is working well

I need to replace a very old Bitron, my electrician told me it has 6 wires. Would this one be compatible? Thanks.

I can’t give you a definitive answer but this may help? This is a 6 wire handset. I purchased it to replace a 4 wire handset, as the advert states Universal. It wasn’t a suitable replacement for me but maybe what you are looking for. I received a swift refund after returning it.
