Why does my smoke detector have 3 wires?

What wire do you use for smoke detectors?

Either a 15-amp circuit (wired with 14-gauge wire) or a 20-amp circuit (wired with 12-gauge cable) is acceptable for powering hardwired smoke detectors. Wiring the smoke detectors is fairly straightforward for an experienced DIYer or a professional electrician.
