The smoke detectors are currently wired to each other (2 wire) on a dedicated circuit. We want to add something that gets used often, so that we'll notice if the circuit has tripped.
We would like this something to be a light that is one a three-way switch. I am guessing this is not possible if the light is closest to the source, because when the light's off the smokes won't get power. But what if the light is at the very end of the circuit? Would this work ok?
If a light on a three-way switch is not possible, can we do a light on a one-way switch, and just ignore the red wire when we go to wire that bit, ie run the red through but don't connect it to anything. Thx
