Really liked the idea of having a voice warning that tells what the problem is and was thrilled at how easy the installation was...for about 48 hours.About two days after initially installation, started getting a "beep" but no voice indication of low battery/other. We always keep spare batteries in stock so decided to replace the batteries with fresh ones and problem seemed to go away. Temporarily. A few days later the alert goes off again which of course, signals ALL of them to go off as they are interconnected. This time it indicates a dead battery. Odd since we replaced them but figured our batteries may have been older than we realized. Went to the store and bought all new batteries - replaced in all five units. A few nights later - about 2 in the morning - we get a full fledged alert with the 'WARNING -FIRE!" screeching through...

I'm guessing that wherever these are manufactured, they are taking a boat trip at least once before hitting a warehouse to wait for me to purchase.I recently replaced my 10 year old BRK detectors around my entire house. I installed the Kidde PI2000 dual sensor detector in each beadroom and a Kidde KN-COSM-IB smoke and carbon dioxide detector in the hallways in the basement, first and second floor hallways. I researched first alert, brk, and kidde, mostly because I could see them at my local big box hardware store. I chose Kidde becuase it had more features for the wired-in detectors than both first alert and brk. First alert appears to have focused their current lines on battery only units and wireless communications. Brk also had limited options in dual sensors or combo CO detectors in a...

Hookup took less than 5 minutes, just replaced old pigtail connector, with the included Kidde connectors. The Kidde base feels more sturdy and the sure-lock twist design guaranteed a perfect fit. The Kids love the "voice" warnings (test mode) for Fire & Carbon Monoxide...I also love the visible 120v power indication (green light). Did I mention that Amazon.com has the best price on this unit...yeah, pick one up! |
