Review on BRK SC7010BV First Alert Hardwired Photoelectric Smoke and CO Detector with Voice Alerts by Predrag Hall

This alarm clock keeps waking us up in the middle of the night just like the others. We blow with compressed air, vacuum, Installed by a professional electrician. I looked at another. We will also replace them after the "recall" but if you are reading this just try a different brand. I tried calling to get a free replacement and they told me they had no guarantee. A $50 detector that needs to be replaced every 2 years? Also needs care and still keeps you awake? Go to another place.
