Same Model But Different Connectors

It replaces the exact unit that was hard-wired in my home. The one I am replacing is about 15 years old. The connectors are different on the new model and won't fit the older model for just plug and play, but there are new connectors provided you can install. It has the compatibility with the other detector in my home which will activate when one or the other detector goes off. It means that if one detector senses smoke, that detector will activate the other detector(s) and all will sound alerts.
