10 Year Worry-Free Hardwired Combination Smoke and Carbon Monoxide Detector with Voice Alarm and Ambient Light Ring

A:  Hello. No. If you want wireless alarms, you will need the alarms to be the P4010ACSCO-W model 21028759

A:  Hello. No, but we have alarms with digital radio wire-free interconnect. Check out the P4010ACS-W model 21028757, the P4010ACSCO-W model 21028759, the P4010DCS-W model 21028753, and the P4010DCSCO-W model 21028747.

A:  Hello from Kidde. Yes, the plastic piece and 3 prongs (which is a plug) have 3 wires that are black, white and red coming out of it. This accessory to the alarm is what we call the "wiring harness" and is used when hardwiring smoke and carbon monoxide alarms.

A:  I purchased these years ago, so my memory may be weak on this. But the harness, or wiring harness, is the wiring that attaches the house wiring to the smoke detector. The red and black wires (I think these were the colors) attach to the two wires (common and hot, respectively) from your house current (make sure that you turn the circuit breaker off first) and the green wire attaches to the ground connection (the metal box is grounded). Then the three prong plug attaches to the smoke detector. Then tuck the wires into the box and attach the smoke detector to the mounting ring (it twists on). I think I have this right, as it has been a few years. I installed four of these to replace the old expired ones, so the wiring was already installed from the old units.

A:  Hello. By both of the plugs, I assume you mean the wiring harness plug with three tinned stripped wires that comes in the package that gets wired up in the ceiling to the 3 wire circuit of your house and the second plug on the alarm itself that plugs into the wiring harness. If so, then the answer is yes. The wiring harness does need to be wired into AC power into a 3 wire circuit if you are interconnecting the alarms or on a two wire circuit if you are just using the alarm as a single station alarm that doesn't communicate with other alarms. The alarm itself needs to be plugged into the wiring harness plug and get AC power. This is an AC powered alarm. If this alarm comes with a wiring harness and two adaptors then this would be a different model then this alarm. The adaptors we have are to adapt certain older FireX and First Alert/BRK wiring harnesses for use with Kidde alarms. You don't have to use these adaptors and can just use the wiring harness that comes with the alarm. For further information or if I have these assumptions wrong, please call us at 1-800-880-6788. Please have pictures of both plugs you are talking about ready to email to us.
