I currently have six interconnected smoke alarms installed. One of them repeatedly gives the low battery indication (chirping) even with new batteries. Can I remove or disconnect this one unit without compromising the performance of the other alarms?

Answer: 
Yes, you can remove or disconnect a unit and still keep the integrity of the system. I would recommend however, that you replace the defective unit as soon as possible.

Answer: 
You can just disconnect it if it is the last one from the power source. Just make sure you wire nut the wires as they will still be hot. If not, you may still disconnect it, but you must still continue the power and red link wires to the next smoke alarm, which would only entail wire-nutting the wires....white to white...black to black and red to red. And of course codes require the use of a blank plate Read More

Answer: 
Yes, it's part of how to deal with the ultimate "long term" failure of single units. After numerous years, it is the radioactive *sensor* that goes bad and the one unit needs to be entirely replaced. The "low battery indicator" in such cases is only a "not willing to work any more" indicator. I've had to do the same "disconnect one alarm unit" and remove it until I got the replacement unit.

3 wires or 2?

This question is from Hardwire 120-Volt Inter Connectable Smoke Alarm with Battery Backup (6-Pack)
Asked by

September 10, 2015
Do these units have 3 wires or 2? In the picture it shows 3 wires with no connectors, a red, a black, and a white. The text description says 2 wires. Thats a bit confusing. I am replacing 6 existing hardwired units from a different brand called USI that have 3 wires, a black, a white, and a yellow. I'm going to have to splice the connectors off the old detectors and onto these new ones but want to make sure that these have 3 wires as well. Thanks.

These units have a THREE prong connector into which an assumed *three* hard wired prong provider in the ceiling are expected to connect. Because of the hassle of dismounting the unit(s) when the battery requires replacement (about once a year), the use of the plug in connector could be an advantage IF your three wires can be assembled into an appropriate provider of the required three prongs.

Answer: 
You nee 3 insulated conductors (wires) Black ,White, Red. You will use all three wires if you have interconnected SD's. If the SD's are not interconnected you will just use the black & white wires. The red wire is factory insulate and does not get used.

Answer: 
The ones I received had three wires black, white and red. The black and white are for the power (the only ones used in my installation). The red is if the smoke detectors are inter-connected. The back and white wires came pre-stripped, ready for wire nuts. The red was capped, since I didn't need it I didn't look too closely at it except to make sure it wouldn't short out.

Hello DJ Mixmode. The wiring harness for this alarm is 3 wires and this alarm does wire in to a 3 wire circuit. It will have a hot black wire, a white neutral wire, and a red interconnect wire. You will need to take down all of the old USI alarms before putting up any new Kidde alarm, as the Kidde alarms do not work with USI. If you have further questions about this, we would be happy to answer them at Read More

Hello Dakota8. Yes, you can then purchase one more Kidde hardwired alarm and they will all work together. Do know that you will probably have to change out all of the wiring harness plugs and rewire in the new plugs that come with the new alarms and you will probably have to change out all of the mounting brackets with the new ones that come with the new alarms.

I used these to replace detectors from ~1999 and did not have any problems. The connector is the same. The original base attached to the ceiling had yellowed and did not match the new detectors. So, I replaced the base, but not the wiring.
