This device is part of our Type 2 Model, allowing a mixture of Wired and Battery Detectors.

Yes, both smoke and heat can be linked, mixing both wired and battery power, meaning if you have wired devices on each level, but want to add a battery heat detector in the living room or a battery heat detector in the kitchen, or any other room, you can do this without needing to run intrusive cabling.
