Product Overview

The Kidde Hardwire Inter-connectable Ionization Smoke Alarm with Battery Backup makes it easy to expand the protective coverage of your current interconnected system. A single 9-Volt battery is all it takes to provide backup protection to you, your family and your home or business in the event of a power outage. The alarm uses wireless technology via a radio frequency to both transmit and receive messages about the presence of invisible fire particles, so when 1 smoke alarm sounds others also become activated.

  • Contains a ionization-sensor to detect invisible fire particles
  • Creates a wireless interconnected system
  • Radio frequency communicates with battery operated wireless units
  • When one alarm sounds, all link units sound
  • Compatible with Kidde 0919-9999/RF FM DC
  • Smart touch hush button silences a low-battery chirp for up to 12 hours
  • Smart touch push and hold button to test the operation of the alarm and interconnected system
  • 9-Volt battery backup

Customer Questions & Answers

does this hardwired alarm pair up with wirless alarms of the same type?

If so which model numbers do I need?
Asked by: Missfixit
Hello Yommot. Homes built in the last 15 years may have an interconnected smoke alarm system. If all alarms sound when you test, you have an interconnected system. If your home fits this description, then you want to purchase one Kidde Wireless AC Powered Smoke Alarm to replace only one current smoke alarm. This Wireless AC alarm now acts as a bridge between the current system and other Kidde Wireless products. Purchase Kidde Wireless Battery Powered Smoke Alarms to be installed in additional rooms

Can this be used with existing hardwired interconnected system?

I have a job where there are three interconnected hard wired smoke detectors. Fire inspector wants another one in a room that would be almost impossible to get the interconnecting wire to. Could I replace one of the existing detectors with one of these and then add another one in the new location, so that the wireless detectors will operate with the existing hardwired interconnected detectors?
Asked by: Dave
This is a warning to others. According to the Kidde company support these will NOT work with an exiting system unless all the rest of the detectors are compatible Kidde brand detectors. That means you would be forced to replace all of the existing detectors on the system. I think that stinks, since the interconnect wire is just basically a switch it should be able to trigger any other detector regardless of the brand. This is very disappointing.

Can you use multiple 120-Volt units to create an AC powered wirelessly interconnected smoke alarm system?

Asked by: BCskier
I read the manual for the hardwired unit, and it says you cannot use more than one of the hardwired wireless interconnected units (model RF-SM-ACDC) in a system. You can use one of them with many of the battery powered units. See Kidde website, and you can not only see the specs, but you can download and read the manuals.

Hi, I have 6 hardwired smoke detectors in my home. 4 of the 6 are interconnected by wire. The last 2 do not have a wire interconnecting them and I can not get an interconnect wire to these 2. I need to know what model numbers I will need to have all six interconnected and the location of them (meaning interconnected by wire or not). The 4 that I currently have interconnected are FireX model i4618. The other two will be replaced. Thanks
Asked by: Jim
Hello Jim. To make this work, you will want to replace one and only one of the 4 interconnected I4618's with the RF-SM-ACDC, Model # RF-SM-ACDC, Internet #100655551, Store SKU #974677, Store SO SKU #198092. This alarm will act as a bridge between the alarms that interconnect through the wires and the alarms that interconnect only wirelessly. Then in the two remaining locations where there is no interconnection, you can either use this alarm, the RF-SM-ACDC, or you can use the battery-only alarms Model # RF-SM-DC, Internet #100655041, Store SKU #974446, Store SO SKU #198092. This will interconnect your alarms together. We are Kidde Product Support at 1-800-880-6788. Thank you for your interest

Hardwire Wireless Inter-Connectable 120-Volt Smoke Alarm with Battery Backup is rated 4.7 out of 5 by 26.
Rated 5 out of 5 by from Connects to wireless detectors and older hardwired detectors Excellent detector and simple install! I had 6 older hardwired detector that I wanted to slowly upgrade and add a battery powered detector in another room that would connect with the other detectors. I purchased this wireless hardwired detector and a wireless battery detector. Install took 4 minutes each and a few pushes of buttons and the detectors were connected!

Rated 5 out of 5 by from Replacement units, easy to,order and install This unitneed to be replaced every 10 years. Therefore when my old unit started to "chirp" I ordered the exact replacement and have it in a few days. It can with the battery for battery backup. It simply plugged into my existing base and we're all set. I was happy to see that Home Depot carried the replacement units, even though the original unit was 10 years old.

Rated 5 out of 5 by from Works well Purchased to replace same item in operation without failure for 10 years. Works well with battery operated model of the same series. When one detects smoke they all sound the alarm. I will purchase again 10 years from today.
