10 Year Worry-Free Smoke Detector, Hardwired with 10 Year Battery Backup, Smoke Alarm

A:  Yes

A:  Hello. Yes, it can interconnect if it is on a 3 wire circuit as shown in the owner's manual with a hot 120V wire, a neutral wire, and a 3 wire for interconnection that just goes from alarm to alarm to alarm and does not hook up to the circuit breakers. You can not use a ground wire as the interconnect.

A:  Yes, if the units you are replacing are connected, and you are installing in the same spot.  My existing units / home wiring (power) had the third wire connecting all units in the home.   This product connects the same way (hardwire).  I purchased these to replace older battery backup units mounted on high ceilings  - difficult access to replace battery.  These do not connect via Bluetooth or other wireless method. Good choice for direct replacement.  

A:  Hello. There is no direct replacement for your alarms. That being said, you can use any of our current alarms to replace your older alarms. You will have to take down all of the older alarms before putting up any new alarms. You will have to change out the mounting brackets at each location but that will just take a screwdriver to change out. You will either have to change out and rewire the wiring harness plugs at each location or you can choose to use the KA-F2 adaptors to adapt the old plugs to our new alarms. The adaptors would plug into the old plugs and the new alarms would plug into the adaptors. The model for the adaptor pack is the 21028461 which includes the KA-F2 and the KA-B2 for some of the older BRK/First Alert plugs.

A:  Hello. The alarms come with Kidde wiring harness plugs to be wired in, yes. They don't come with wiring harness adaptors to adapt plugs from other companies to our alarms.

A:  Yes

A:  Hello. Yes. If the alarm is getting AC power from the wiring circuit then the alarm should be getting AC power. If it is a flashing green every 60 seconds then the unit is running on battery alone and either not wired in or not getting AC power. Call us while on location with a ladder ready at 1-800-880-6788 so we can figure out what is going on.

A:  Yes
