I have 5 Model # 7010B detectors hardwired. Can I hardwire 1 Model #9120B and have them interconnected and alarm together?


Thank you for your question. These two models can interconnect. All modern hardwired First Alert, Onelink, and BRK alarms use the same wiring technology and can interconnect. If you have any additional questions, please don't hesitate to reach out directly to our Support Team at First Alert.
