HPM have a wireless door bell system D641/PILR (70M range) that is programmable up to 6 separate stations/frequencies, however we need to have
12 separate stations/frequencies as there are 12 rooms.Has anyone had any experience with these and has managed to get them up to
12? Or can anyone recommend another solution that could include a 12 button keypad. Is there a 12 station wirless intercom system available - it would also do?Hard wiring, BTW, is out of the question.
Thanks for any help, David.
