Figuring out Wire Colours
To find out the operate of every wire, it’s good to establish their colours. The most typical wire colours you may encounter in a hardwired smoke detector are:
Wire Colour Perform Black or Purple Line (120 volts) White or Grey Impartial (0 volts) Inexperienced or Naked Copper Floor In some instances, you might encounter different wire colours, resembling 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 operate. 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 can have no voltage studying.
After you have recognized the operate of every wire, you may proceed with the substitute course of.
Reattaching the Energy
Now that the brand new smoke detector is in place, it’s good to reconnect the ability. Comply with 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 Take away the outdated smoke detector from the ceiling 3. Disconnect the wires from the outdated smoke detector 4.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 may activate the ability on the circuit breaker. To do that, merely flip the breaker swap to the “on” place.Testing the New Detector
