My interconnected smoke/CO detectors are all going off. Can I silence them from any unit, or just the one that detected the issue?

Usually, you can only silence the specific detector that first sensed the problem and triggered the alarm. While interconnected units all sound, only the originating one typically has the functional 'hush' or 'test/silence' button to clear the alert. If you can't find the source or it keeps alarming, it's an electrical issue, not plumbing; get a licensed electrician or fire safety company to inspect it promptly.

Subfloor is designed to be fastened from the top, pulling it tightly down onto the joists with construction adhesive to prevent movement. Attempting this from underneath often won't create enough pressure to eliminate squeaks or ensure a lasting, stable connection.
