A device used to detect any breach in the insulator, usually made out of rubber or some sort of plastic, in a wire.
It basically checks for any part in the wire that might get you electrocuted.
The proper 3 wire smoke detector wiring diagram for installation involves connecting the black wire to the hot wire, the white wire to the neutral wire, and the red wire to the interconnect wire. Make sure to follow the manufacturer's instructions for your specific smoke detector model.
Check it with a voltmeter or with a voltage detector.
To effectively use a wire detector to locate wires in walls, start by selecting the appropriate setting on the detector for electrical wires. Hold the detector against the wall and slowly move it horizontally and vertically to scan for wires. When the detector indicates a wire is present, mark the location and proceed with caution to avoid damaging the wire during any renovations or repairs.
When something is hard wired, it is wired directly to the house wire. No cord. You just install the smoke detector like you would a light fixture or an outlet.

The live pole carries the supply voltage and is usually colored brown or red. The neutral pole completes the circuit and is typically colored blue or black. Using a voltage detector or a multimeter set to AC voltage mode, you can identify the live wire by measuring the voltage between each wire and the ground, as the live wire will show a voltage level.
Using a non-contact voltage detector or a stud finder with a live wire detection feature can help locate a current carrying wire concealed in a wall. Move the detector along the wall to identify the presence of live wires without having to physically access them. It is important to exercise caution and follow all safety procedures when working around electrical wiring.
black should be your hot white your neautral and the red should be the interconnect to another smoke alarm so that if one goes off in the upstairs the down stairs one will go off also because they are joined by the red wire(interconnected) check for another smoke detector(the red/black/white)should be fed from it to were you are talking about
yes it does
Sure if there is enough metal like steel rebar
Detector rails generate redstone energy (for a redstone wire or other contraption) when a minecart is on them. You can make a simple minecart accelerator by placing rails like so: [minecart rail][detector rail][powered rail][powered rail][detector rail][minecart rail]
