[SOLVED]Interfacing with house alarm - Raspberry Pi Forums

-

this maybe straightforward question, unsure if in correct part of forum please excuse me in advance.

attempting expand house alarm remote building using ciseco wik. have working (both communicating) , python programme functionality there in terms of polling see if both wireless transceivers still connected , in alarm state.

however, question is, rpi sitting alarm panel , when panel armed, want rpi close zone on alarm. these n/o when not in alarm state , closed when alarm detected. need use relay close switch on alarm panel or can i/is advisable attempt close directly gpio pins? i'm guessing former, not latter don't want overcomplicate project if 0v switch can switched directly

i think has circuits... need relay if more pi can handle sometime have 1 make sure pi isn't damaged in crazy surge or not mite on kill said ... test go how low of signal out killing max of pi ... bet if make test see alarm needs switch on input have already.... alarm... know if pi handle spec info
