the interconnecting part pretty much assures that they'll be on the same circuit,
I did not know that this was a requirement.
I run just a single signal wire between them and tap the detector into a convenient box.
If the breaker trips on the circuit with the detectors, it would be noticed quicker if it shares a circuit with commonly used devices such as lights, that's the argument presented to me on sharing the circuit with lighting.
That's my opinion too. But somewhere I saw a requirement for a dedicated circuit... perhaps along the line that if the lights melt down, start a fire, and blow the breaker, the smoke detector should still be active.
I use dual-powered devices (120 V AC and 9V battery) which avoids that concern.
