Time to replace five hardwired detectors July 4, 2014
Reviewer: Larry Jones from Johnson City, TN United States  
We have five hardwired detectors with battery backup in our home. The unit directly outside of our bedroom began to chirp at 3am. I changed the battery and still chirped. I found later that it will chirp if the radioactive material had been depleted. I found upgraded units with dual functionality, same wire harness & less money than the home stores...plus, these guys are firemen and that was good enough for me!

Was surprised to learn that a tool (small screw driver) is needed to open the backup battery compartment.

First Alert 3120B July 1, 2014
Reviewer: John Adkins from Westerville, OH United States  
These units were easy to install and set. They are low profile to the ceiling and attractive. The battery compartment is placed in a very good place for ease of access.

First Alert 3120B Hardwired Photoelectric and Ioni June 24, 2014
Reviewer: Alan Streitman from Palm Harbor, FL United States  
After 20 years I needed to replace my wired smoke alarms. I researched all the available products and found that SmokeAlert sold the best products at the best prices. Their excellent technical support and fast free shipping is head and shoulders above the competition. I have recommended them to all my friends and family.
