Summary
Aurora's Electrical Code confirms smoke alarms are required in new dwelling units and requires their branch circuit to also carry habitable-space lighting outlets, not stand alone on its own circuit.
111.5 Smoke alarm circuits. Single- and multiple-station smoke alarms required by this code and installed within new dwelling units shall not be connected as the only load on a branch circuit. Such alarms shall be supplied by branch circuits having lighting loads consisting of lighting outlets in habitable spaces.
Full Breakdown
Aurora, Illinois (Kane County) enforces this wiring rule citywide. The city's Electrical Code confirms smoke alarms are required in new dwelling units and sets an installation standard for them: single- and multiple-station alarms can't be wired as the sole load on a branch circuit, that circuit must also carry lighting outlets in habitable rooms, so a tripped outlet or appliance breaker can't silently take the alarm down with it (§ 111.5).
Violations & Fines
Wiring a required smoke alarm as the sole load on a branch circuit fails electrical inspection; the permit won't close until the circuit includes habitable-space lighting outlets.
