Features

  • [Hardwired interconnection] Up to 12 smoke alarms can be interconnected to cover your entire home. When one detects smoke, they all make a sound to alert everyone in the house, creating an interconnected safety net for your home.
  • [9V Battery backup] Hardwired smoke detectors are equipped with DC 9V batteries. Ensure that all units are always connected and continue to function properly, even in the event of a power failure. Low battery alarm reminds you to replace the battery as soon as possible. If an error occurs, the system automatically triggers the fault mode, prompting you to check the device.
  • [Test Mute button and LED light] It is connected with other alarms. Just press the test/mute button on one of the units to test or mute the entire interconnected system. If the smoke alarm is in normal working condition, the green LED light is always on and the red LED light flashes every 32 seconds
  • [Photoelectric smoke sensor] Based on advanced photoelectric technology, smoke alarms can be more sensitive, fast, accurate measurement of smoke levels. More than 85 decibels of alarm sound, you can more clearly hear the danger coming.
  • [Simple installation] The installation of smoke alarm is very simple. The AC connector is connected only to the mains power and signal cables. (Please connect as instructed)

  • Simple to install
Style: Hardwired Interconnected Model Size: 4 pack
This is only the second time i've needed to install smoke detectors in a home. The first time, I was a newer homeowner and "afraid" of doing wiring changes myself - so I bought detectors that were an exact match for what I was replacing, so that the current "plug attachment" that was in the ceiling matched. But now, i've learned it isn't really that hard at all to do to replace the wired harness. Obvious first step is to turn off the circuit breaker that powers the detectors. This was probably the most "annoying" part of the job - because it was on a circuit that didn't make really any sense and I had to try like 6 circuits until i found the right one. I confirmed I had the right one with a "non-contact" voltage tester. Then remove the old detector and mounting plate and that will give you access to the wiring. All you have to do is remove the current wiring nuts for the black, white and "communication" wire - which could be red or yellow. After that wire back in the new harness to the previous locations. I even re-used the original wire nuts. Be sure to install the included 9V battery - and a NOTE - there is a little packet of screws and drywall anchors in the batter compartment. At first I thought it was just some packing material for the battery compartment to hold down the "missing battery lever" that prevents closing the battery door. The only issue I experienced with the installation was that the mounting plate's holes design didn't perfectly match up with the currently installed electrical box, I got it to mount up - but with a bit of cross angle on the mounting screw. Testing after install, they all worked as intended. This was installed on my father-in-law's condo that we were getting ready to sell... and it passed the home inspector's testing, so that's proof they worked well and I installed correctly - LOL! ... show more

  • continued to false alarm
Style: Hardwired Interconnected Model Size: 4 pack
Alarms continued to false alarm and had to replace them a few times to find one or two that would last only a few months. Now I'm out the total cost as they have all failed. as a safety item I had to just give up and take the loss. I would not recommend.

  • Easy to install
Style: Hardwired Interconnected Model Size: 4 pack
They were easy for my 14-year-old grandson to install for me. He had to do four of them that were interwired across my house. They also look a lot better than my old discolored ones. I'm really happy that I replace the old ones with these updated new ones.
