A: Hello. All connections should be made by a qualified electrician and all wiring used shall be in accordance with articles 210 and 300.3(B) of the U.S. National Electrical Code ANSI/NFPA 70, NFPA 72 and/or any other codes having jurisdiction in your area. The appropriate power source is 120 Volt AC Single Phase supplied from a non-switchable circuit, which is not protected by a ground fault interrupter. It is not specifically rated for a 20 amp circuit.
A: Hello from Kidde, Going through clear air, the distance is about 300 ft. However, this does not take into account the walls in a home. The material of the wall can make a difference. For instance, whether it is made of sheet rock, brick, concrete (perhaps a basement ceiling or wall), metal or other type of material. Also, the interconnect system must not exceed the NFPA (National Fire Protection Association) limit of 12 smoke alarms. Wireless Kidde alarms can be added later, as long as the limit of 12 has not been reached. Each of the smoke detectors communicates directly with the "hub" alarm which acts as a coordinator.
A: If the hardwired alarms are from Kidde and interconnected, then install this alarm in one of the locations and you can then add a battery operated only unit, e.g. P4010DCS-W, which can interconnect wirelessly with them.
A: Hello Billbo, These units do not require internet. They have an antenna inside of them to communicate with one another.
