You are required to have a box at the location. You can use round remodel boxes or the regular single gang remodel boxes. For existing construction I like to use the round remodel boxes as it is easier and quicker to use a hole saw to cut out the drywall for a round box.
Can I add a wireless smoke detector to a wired system?
Place one mains powered Smart RF enabled smoke or heat alarm on the existing hard‑wired network. This will link all other Smart RF alarms or accessories to communicate to hardwire interconnected alarms.
How are hardwired smoke detectors wired?
Modern hard-wired smoke detectors don’t have wires in the back that need to be connected to loose wires in the ceiling. Most hard-wired smoke detectors have a connection from the electrical wires to the smoke detectors that engages and disengages. It’s like a plug.
Do smoke detectors have to be on a dedicated circuit?
Residential smoke alarms should be wired on a dedicated circuit. It’s a good idea to have at least one light or receptacle-on the same circuit, to alert the homeowners in case the circuit breaker ever trips. Interconnected alarms are usually wired in a daisy chain, using 14-3 or 12-3 cable.
Why are smoke detectors hard wired?
Hardwired smoke alarms can be interconnected. So if one detector fails, all the other alarms are triggered. In case of fire, the interconnection can save precious moments as the detector sounds the alarm simultaneously with all other alarms connected into it.

Connect the white wire on the power connector to the neutral wire in the junction box. Connect the black wire on the power connector to the hot wire in the junction box. Connect the orange wire on the power connector to the interconnect wire in the junction box. Repeat for each unit you are interconnecting.
