About this item

  • DETECTS SMOKE: Sounds a loud 85-decibel alarm when smoke is detected - 3 long beeps with red LED light flashing in time, repeating.
  • HARDWIRED & 2 AA BATTERY BACKUP (Included): Operates on 120V AC wiring (installed in the ceiling) with 2 AA alkaline batteries that provide battery backup coverage during power outages.
  • ENHANCED SENSING TECHNOLOGY: Reduces false alarms often caused by cooking. Comprehensively tested to meet the latest UL standards, meets UL 217 9th Edition & FCC standards.
  • SELF-TESTING ALARM: Internal components ensure alarm is always operating as expected. Not a substitute for a manual push test, perform a button test once per week to verify alarm operation.
  • INTERCONNECT CAPABILITY: When one alarm sounds, they all sound, so you can get out faster. (Different models offer different interconnection options and requirements. See User Guide for more info.)
  • 3 LED NOTIFICATIONS: LED lights indicate alarm status, green = normal operation, amber = operating error, red = smoke detected.
  • TEST & HUSH BUTTON: Makes it easy to test the 5-inch smoke detector and silence false alarms, should they occur.
  • 10-YEAR LIMITED WARRANTY: Warranty begins when the alarm is powered on. If that date is unknown, it should be assumed that alarms should be replaced.

This 4 pack works great. Arrived on time and was well packaged. This is the same Kidde detectors you will find in Home Depot and Menard's, but less expensive, by at least 10%. Installation was easy with no problems. I would definitely purchase from Amazon again vs. my local stores.

I purchased another brand, which I liked, but the unit(s) failed at install. So, I tried Kidde. The directions were good, but the print was small. Also, hardware likes screws and wire nuts were not included. I turned off house breaker and tested house wires for power. Then, reading the directions again and watching a Kidde install video, I installed 10 of these units in my house. There was a slight learning curve. But, after install, I applied power again, they all worked perfectly without a single chirp! Testing was quick and easy. I recommend buying the ten-year battery model as the AA model batteries must be replaced once a year. The ten-year battery models were available if I wanted to wait another week for delivery. Kidde claims these alarms are “UL listed” which I need to meet my city building code. These were a great smoke detector replacement.

I've got 10 of them, easy to install, work as well as the originals, couldn't be happier and feel safer. I also got some with carbon monoxide detection, all of them work perfectly together on the same system in my house.
