Smoke hook up

smoke hook up

How do you hook up a smoke detector to a box?

Tie the bare copper ground wires together and run a pigtail to bond it to the box. Connect the red wire to the interconnect wire from the smoke detector. This wire will usually be marked and is usually a yellow wire. Make each connection with a wire nut big enough to cover all exposed wires.

Where can I find information about smoke detector wiring and installation?

For guidelines on where to install smoke detectors, check out Smoke Alarm Placement for Home Security Systems. For help finding problems with smoke alarm wiring, check out Smoke Alarm Circuit Troubleshooting for testing wiring at the main alarm panel. For checking connections in the field, see Troubleshooting Smoke Alarm Wiring at the Detectors.

Why run an extra 4-conductor wire for smoke detector wiring?

For 4 wire smoke detector wiring, running an extra 4-conductor wire gives the same effect. The extra run of 4-conductor wire gives us a return path to the panel.

What color wire is used for smoke detectors?

Published on Jan 27, 2012. Typical household smoke alarms use a black wire for detecting smoke, a white wire as the common conductor and a red wire that communicates with other smoke detectors in the home.

How do you wire a smoke detector to a metal box?

Join the black circuit wire (s) to the black wire lead on the smoke detector. Connect the white circuit wire (s) with the white wire lead on the smoke detector. Connect all bare copper ground wires together. If you are using a metal box also attach a bare copper or green insulated pigtail wire to the box.

How does a smoke detector wiring harness work?

The smoke detector’s wiring harness has two parts: the fixed wires and the wires that protrude from the harness. You should be able to see three wires coming out of the harness: white, black, and yellow. The black and white wires are used to connect to the power source, and the yellow wire connects to the other smoke detectors in a series.

What color wires come out of a smoke detector?

You should be able to see three wires coming out of the harness: white, black, and yellow. The black and white wires are used to connect to the power source, and the yellow wire connects to the other smoke detectors in a series.

What are the parts of a smoke detector?

Wiring Parts. The smoke detector’s wiring harness has two parts: the fixed wires and the wires that protrude from the harness. You should be able to see three wires coming out of the harness: white, black, and yellow.

What kind of wire do you use for smoke detectors?

Hard-wiring also involves interconnecting all the other smoke detectors together with the first smoke detector using a 14/3 cable. The 14/3 cable is composed of a black, a white, a ground wire, but also an extra wire which can be red or yellow, the red being more commonly available.

What is the difference between a 2-wire and a 4-wire smoke detector?

Notice that the blue & brown pair of wires has the same end-of-line resistor (EOLR) hookup as the 2-wire smoke. This resistor is “seen”, electrically, back at the main alarm panel, and verifies that the smoke detector wiring is unbroken. Unlike the 2-wire smoke, a 4-wire smoke must also supervise the second pair of wires used for supplying power.
