Be aware: Some smoke detectors have screws that have to be eliminated to detach the faceplate.
Figuring out Wire Colours
To find out the perform of every wire, you have to determine their colours. The commonest wire colours you may encounter in a hardwired smoke detector are:
Wire Coloration Perform Black or Pink Line (120 volts) White or Grey Impartial (0 volts) Inexperienced or Naked Copper Floor In some instances, you might encounter different wire colours, corresponding to blue, yellow, or orange. These wires sometimes serve particular functions throughout the smoke detector’s circuitry and shouldn’t be related to the road, impartial, or floor wires.
If the wires in your smoke detector usually are not color-coded, you should use a multimeter to find out their perform. Set the multimeter to the AC voltage setting and contact one probe to every wire. The road wire will learn 120 volts, the impartial wire will learn 0 volts, and the bottom wire could have no voltage studying.
After you have recognized the perform of every wire, you’ll be able to proceed with the substitute course of.
Reattaching the Energy
Now that the brand new smoke detector is in place, you have to reconnect the ability. Observe these steps:
1. Flip off the ability on the circuit breaker 2. Take away the outdated smoke detector from the ceiling 3. Disconnect the wires from the outdated smoke detector 4. Join the wires to the brand new smoke detector 5. Mount the brand new smoke detector to the ceiling 6. Activate the ability on the circuit breaker **6. Activate the ability on the circuit breaker**
As soon as the brand new smoke detector is mounted, you’ll be able to activate the ability on the circuit breaker. To do that, merely flip the breaker change to the “on” place.Testing the New Detector
