Sounds like a voltage feed for the solonoid is missing.

When flat buzzer is pressed , buzzer rings in flat , we lift handset ,
switch on base unit extends . We can hear person outside speak but they
are unable to hear us . We then de-press button on base unit for them to
enter. They can hear a buzz at door but lock does not disengage and are
unable to enter. Any ideas what could b the problem. Handset and base unit
where knocked
off the wall. Souldered connection onto privacy switch had came off. I
resouldered wire and was then able to hear person outside speak . Thought
I had cracked it but unfortunately lock still not coming off.
Cheers john
