我不是imore，我和imore一样都是专家们说的棒槌。
但既然专家们哆哆嗦嗦的不敢回答，我来回答。
Black
Black is used for power in all circuits. Any circuit's black wire should be
considered hot or live. Black wire is never used for a ground or neutral
wire and should be used as the power feed for a switch or an outlet. A black
wire is often used in a circuit as a switch leg, the connection that runs
from the switch to the electrical load.
Red
Red indicates the secondary live wires in a 220-volt circuit, used in some
types of switch legs and in the interconnection between smoke detectors that
are hard-wired into the power system. You can connect a red wire to another
red wire or to a black wire.
White and gray
White and gray indicate a neutral wire. White is the color most often used
for this function. A neutral wire connects to the neutral bus bar within an
electric panel. (A bus bar is made of conductive metal that attracts the
electric current for distribution outward to feeders.) You can connect white
and gray only to other white and gray wires.

RTFM！我都看到你下面那张纸上就有接线图了，字太小看不清。
红线有可能是串联多个警报器用的，一个测到全屋警报。

看说明，一般来说接黑接line，白接neutrual，红既然cap了，就不管，可能接高压的
，或者是并联出去的。
