I have an ancient Eurotec board, and it uses an battery-backed siren that goes off as soon as its input drops. It provides 14.6V to this siren.
The sensors are provided with 13.8V, and there's a reset function for smoke detectors. As far as I can tell these are normal sensors, and unfortunately they have been installed with tamper resistors properly installed near the device.
Can I replace this system with Konnected?
