Is there any sort of adaptor that would replace the control box of a burglar alarm? Until a few months ago my workshop was protected by a wired burglar alarm system (Pyronix I think) but the main box died of old age. All of the sensors are wired and some need a permanent dc supply.
While I could kludge something up with IO pins on the Raspberry Pi, this must be quite a common requirement and it would seem to be a bit of re-inventing the wheel to make something if a well-researched and properly made device exists to adapt the existing sensors to a home automation system.
For scale, my existing system had 4 door/window sensors, 2 PIR motion sensors, and 1 wired smoke alarm. All of the sensors were wired back to the panel, not on a loop as that was the easy way to do it.
