“Bought these to update an old detectors as part of an 12V alarm system. It took some effort and trial-and-error to figure out which connector goes to which wire of the alarm system. One needs to be careful with the connector screw, though, as the thread is easily stripped. Otherwise, they work flawlessly.”
