Why do smoke and CO detectors matter in a Fort Pierce home?
A smoke detector gives you time. A fire can grow fast, and smoke can fill a hallway before you wake up. A detector that sounds early gives you minutes to get out. A CO detector does a job you cannot do yourself. Carbon monoxide has no smell and no colour. A detector is the only warning you get when a gas appliance, a furnace, a water heater, or a generator is putting CO into the air.
Many Fort Pierce homes were built in the 1970s and 1980s, and often have old detectors, detectors that were never interconnected, or no CO detector at all. Look at the date printed on the back. If there is no date, or the date is more than 10 years ago, it is time to replace them.
We install hardwired detectors with battery backup. Hardwired means the detector is wired into the house power, so it does not depend on a battery alone. Battery backup means it still works when the power goes out. Interconnected means when one detector sounds, they all sound.
What is a hardwired interconnected detector?
A battery-only detector runs on a battery and nothing else. It works only while the battery is good, and only in the room where it sits. A hardwired detector is connected to the house wiring and to a battery backup. It draws power from the house, and the battery takes over in a power cut. It is also connected to the other detectors in the house, so they sound together.
That matters at night. A fire in the kitchen should wake the person asleep in a bedroom with the door closed. Interconnection is what makes that happen.
Do you need both smoke and CO detectors? Yes, in most houses. A combination smoke and CO detector does both jobs in one unit. We will look at your house and tell you what fits where.
Where should detectors go in my house?
Placement matters as much as the detector itself. A detector in the wrong place will sound late, or sound when it should not. We follow the placement rules in the current code. The exact edition of the code in force in Fort Pierce is a matter for the permitting authority to confirm. [VERIFY]
Smoke detectors go inside every bedroom, outside each sleeping area in the hallway, and on every level of the house. In a single-storey house, that usually means a detector in each bedroom and one in the hall outside the bedrooms. In a two-storey house, it means detectors on both floors.
CO detectors go outside each sleeping area, and on every level. If you have a gas furnace, a gas water heater, a gas stove, or an attached garage, CO protection matters even more. We do not put a CO detector in a garage itself, because a car starting in a garage can set it off. We put it in the house, near the door from the garage.
Do not put a smoke detector right next to a kitchen, a bathroom, or a shower. Steam and cooking smoke cause false alarms, and false alarms teach people to take the battery out. A smoke detector should be at least 10 feet from a cooking appliance, where the ceiling allows it. Do not put a detector in a dusty attic or a garage.
How old is too old for a detector?
Replace smoke detectors every 10 years. Replace CO detectors according to the maker, usually 7 to 10 years. The date is printed on the back. If you cannot find a date, or the unit is yellowed or cracked, replace it.
The 10-year rule is about the sensor, not the battery. A detector can still beep when you press the test button and still have a sensor that is too slow to warn you in time. Pressing the test button checks the horn and the battery. It does not check the sensor.
Replace all of them at once, in most cases. If one detector is 12 years old, the others fitted at the same time are 12 years old too. Replacing them all at once means one visit, not three.
Why is my detector chirping or going off for no reason?
A single chirp every 30 seconds to a minute usually means a low battery, or the end of the detector’s life. Change the battery first. If the chirp continues with a new battery, the unit may be at the end of its life. If the unit is more than 10 years old, replace it.
A detector that goes off when there is no fire is usually in the wrong place, or dirty, or old. Cooking smoke, steam, dust, and insects can set it off. Salt air, especially on Hutchinson Island and South Beach, can corrode contacts. Do not take the battery out and leave the detector dead. Call us and we will find the cause.
If a CO detector sounds, get everyone out into fresh air. Call 911. Do not go back in to look for the source. Let the fire department check the house. Then call a licensed electrician at (877) 631-1186 to check the wiring and to replace the detector if it is faulty.
How do I test my detectors, and how does installation work?
Test each detector once a month. Press and hold the test button until it sounds. If it does not sound, change the battery and test again. If it still does not sound, replace the unit. Change the batteries at least once a year. Do not paint a detector. Paint blocks the sensor.
Installation has four steps.
First
We walk through the house, count the bedrooms and levels, and look at the detectors you have now and the ceiling wiring. In a house with aluminum wiring, fitted in many Florida homes between 1965 and 1973, we look at the connections first.
Second
We plan the placement and give you a price in writing.
Third
We fit the new units, connect them so they sound together, test each one, and show you how to test them.
Fourth
We pull a permit if one is needed. The permitting authority is the City of Fort Pierce inside city limits, and St. Lucie County outside the city. Straightforward electrical permits are often plan-checked in one to two weeks, but that is a secondary source and we do not promise a timeline. [VERIFY]

When should I call an electrician, and when should I call someone else?
- A CO detector is sounding, or someone feels sick and a CO detector has sounded: get out, call 911 first.
- Fire, or smoke you can see: call 911 first. Get out of the house.
- A detector that chirps, goes off for no reason, or is more than 10 years old: call a licensed electrician at (877) 631-1186.
- A detector that will not test, or a hardwired detector that has no power: call a licensed electrician at (877) 631-1186.
- A power cut that affects the whole street: call your utility. Check your bill to see if your utility is Fort Pierce Utilities Authority or Florida Power and Light. Read more: FPUA vs FPL in Fort Pierce
- A power cut that affects only your house: call an electrician at (877) 631-1186. See Emergency Electrician in Fort Pierce if it is urgent.

Frequently asked questions
How many detectors does my house need?
One inside each bedroom, one outside each sleeping area, and one on every level. A three-bedroom, single-storey house usually needs four or five smoke detectors, plus CO detectors outside the sleeping area and on each level. We count them properly when we walk through the house.
Can I replace a detector myself?
You can replace a battery-only detector yourself. You should not replace a hardwired detector yourself unless you know how to work safely with house wiring. The wiring is live at the ceiling box.
Do I need a CO detector if I have no gas appliances?
If you have no gas appliances, no attached garage, and no fireplace, the CO risk is lower, but it is not zero. A neighbour’s generator or a gas appliance added later can change that. Many homeowners fit combination units anyway.
How long do hardwired detectors last?
Smoke detectors last 10 years. CO detectors last 7 to 10 years, depending on the maker. Change the battery backup battery at least once a year. Replace the unit on the date printed on the back.
Will a new detector stop false alarms?
A new detector in the right place will false-alarm far less than an old detector in the wrong place. If cooking smoke or steam is the cause, moving the detector a few feet usually fixes it. We find the cause before we fit the replacement.
Do you fit detectors in rentals and small businesses?
Yes. We fit detectors in houses, rentals, and small offices and shops. A commercial space may need more units or a different layout. Tell us what the building is when you call. See Licensing and Insurance and Frequently Asked Questions
