I've got a wired Accenta Gen4 setup and would like to add a sounder or audible alert speaker 30 metres (open air) away in the main residence. To notify me the alarm is sounding in that building, even with the loudest of bell boxes it can sometimes not be heard with fans etc going.
Any idea's?
I've thought of a GSM autodialer but it is rather expensive.
