Star Island Smoke detectors should be installed on every level of your home. Make sure to put them in the basement, the attic and include one in each bedroom.
One of the most important safety devices in your home is the smoke detector. At Electrician Network Star Island , our certified Star Island technicians will work to ensure proper placement and installation of smoke detectors in your Star Island home. These smoke detectors can be standalone and simply provide an audible alarm if smoke is detected or they can be wired into most home security systems to alert authorities if smoke is detected in your home. In the Florida, it is required that smoke detectors are installed on every habitable level and in attics that are accessible, and within the vicinity of all bedrooms.
All of our skilled technicians at Electrician Network who work in your home or business are professionally trained, background checked and drug tested. Our technicians also drive fully stocked trucks to ensure they are able to get the job done the first time out to your home or business.
Smoke alarms will sound when they detect smoke. You can get smoke alarms that are specifically designed for different areas of your home.
Use wire strippers to strip 3/4-inch of insulation from the ends of the wires.
Connect the wires to a 120-volt wire harness. Usually the hard-wire smoke alarm comes with a quick connect wire harness.
When connecting the wire harness, use wire nuts to connect the stripped NM cable wires to the same color harness wires. White wires connect to the harness’s white wire and red wires connect to the harness’s red wires.
Only connect wires of like colors.
When connecting smoke alarms to each other, the wire harness should connect to both the wires that run from the breaker panel (power source) and the wires that run between both alarms.
Wrap the wire connectors with electrical tape for extra protection.
Gently tuck the excess wire length and wire connectors into the remodeling box. Leave the plug-end of the wire harness out.
Install Backup Battery
Feed the wire harness through the smoke alarm mounting plate.
Place the alarm’s mounting plate on the remodel box and align the screw holes. Make sure the wire connection runs through the mounting plate.
Use the included screws to connect the mounting plate to the remodeling box.
Plug the wire harness into the back of the smoke alarm.
Open the battery compartment on the alarm.
Insert the correct type of battery (usually a 9-volt battery), being careful to position it so positive contact meets positive contact and negative contact meets negative.
Close the battery compartment.
Attach Smoke Detector to Mounting Plate
Line up the notches on the back of the alarm with those on the base.
Twist the alarm until it locks into place.
Check the connection to ensure it is secure on all sides. Once secured, you’ve successfully learned how to replace a smoke detector.
Connect the other end of the NM cable to the beaker panel. Or hire an experienced electrician to complete this final step for you.
Test Smoke Detector
Once all the wiring is connected at the breaker panel and no one is doing anymore electrical work, turn on the power to the circuit.
Confirm each alarm’s power light is on.
Press the test button on each alarm. You should be able to hear all the alarms each test.
If the alarms don’t sound, turn off the power at the breaker panel and double-check your wiring connections. If the connections are correct but a unit’s power light won’t come on, replace the unit.
A hard-wired Star Island smoke alarm or carbon monoxide alarm is connected to other detectors throughout your home. These alarms sound simultaneously, on all levels of your home, when a single unit detects smoke or gas. All the units are wired to a 120-volt household electrical circuit and each have a battery backup. The battery backup provides extra protection by powering the alarm even if a fire causes the household power to go out. It’s important to learn how to install a hard-wired smoke detector yourself.
Install Remodeling Boxes
To prepare the wiring for an alarm in a new location, you need to install a remodeling box. A remodeling box is an electrical box that can be installed into drywall. This is one of the first steps to learn how to wire a smoke detector.
Identify where the smoke alarm will be installed. This can either be on the ceiling or on the wall 12 inches down from the ceiling.
Use a stud finder to determine the location of wall studs around each alarm location.
Use a marking tool to trace the outline of the wall remodeling box or ceiling remodeling box. Use a level to make sure the box outline is straight.
Drill a 1/2-inch starter hole at the corner of your outline.
Starting at the hole, cut along the outline of the shape with a drywall saw.
Test-fit the remodeling box. It should fit into the hole snuggly. It should not fit so tightly that you have to force it. Do not set the remodel box yet.
Repeat this process at each location where a smoke alarm will be installed.
Run Cable to Boxes
Run 14-2 NM cable (a sheathed cable with 2 wires and a ground wire) from the house breaker panel to the smoke alarm closest to the breaker panel. Do not connect the cable to the breaker panel yet. You’ll do this at the end of the project.
When the cable reaches the alarm location, pull about 10 inches of the cable through the knockout of the first remodeling box.
Run cable from the first knockout to the second knockout, leaving 10 inches of cable hanging out of the work box. Repeat this step until all remodeling box knockouts are connected by cable.
Use wire strippers to strip the sheathing off the NM cable to expose the inner wires.
Insert the wires through the back of the remodeling box.
Insert the box into the hole in the drywall.
Screw down the clamping tabs carefully until the box is tight against the wall.
Attach the copper wires (ground wires) to the box with a ground screw or with the box’s internal clamp, depending on the model.
