Just curious if anyone has damaged their whole apartment intercom system by rewiring the intercom or what is the risk of this actually happening? I’ve recently realised I probably need a new handset and have been reading up and quite a few comments in other forums are that there is a risk of “blowing” the whole system if done incorrectly. I know this is probably more specific to putting in an incompatible handset but also wasn’t sure the risk of fiddling with the current wiring altogether.
I had problems getting mine to work and basically ended up switching - and + on the bus (yes), which led to the standard (non-Nuki) department end going completely unresponsive even though disconnecting the Nuki device, but completely disconnecting everything(!) a couple of minutes and reconnecting waiting a couple of minutes brought everything back alive. I believe these systems are build pretty safe guarded and somewhat self healing (e.g. of shortages) as errors can be critical. However I never got Nukia to work opening doors because the problem was missing support for dual door. It was a Siedle BTS system BTW.
