It is an easy do it yourself job to replace a hard wired smoke detector. Turn off the electric to the circuit that you are working on. Take down the old electrical smoke detector and check to see if it is connected to other smoke detectors. To connect just one unit, you will be connecting the hot and neutral wire.
Whether you choose to go with a hard-wired system or an interconnected system, your smoke detector installation should be completed by a qualified electrician. A professional will ensure that the job is done right the first time in accordance with state and local regulations and standards.
Before attempting any work on hardwired smoke detectors, it's crucial to ensure that the power is off. Identify and turn off the circuit breaker connected to your smoke detector circuit. This step is non-negotiable and is the first line of defense against electrical shock.
Reset the Smoke Detector: Sometimes, a smoke detector just needs a good reset to stop the chirping. You can do this by turning off the power at the circuit breaker, removing the detector from the mounting bracket and disconnecting the power supply. Then, press and hold the test button for about 15 seconds.
If your smoke detectors are yellowing, chirping non-stop, or going off unexpectedly, it's time to call in our electrical pros from Integrity Home Solutions. We can inspect and replace hardwired smoke detectors or install them if you don't have them in place already. Don't take a chance on your family's safety.
"Replace all smoke alarms, including those that use ten-year batteries and hard-wired alarms, when they are ten years old or sooner if they don't respond properly when tested." Each smoke detector should be replaced 10 years after the date of installation.
If your home was built after 1986, it will have at least one hard wired smoke alarm connected directly to your electrical panel. It is not acceptable to replace a hard wired alarm with one that is battery operated. A home must maintain at least the same level of protection as originally required.
Even after the battery has died, the detector maintains a residual charge that will keep the chirp going for at least seven days. To get the device to stop chirping once the battery has been removed, you must drain this residual charge by holding the test button for 15 seconds.
So, if you're asking yourself, “Do I need an electrician to replace hardwired smoke detectors?” the answer is absolutely yes.
Disconnect the wire harness by squeezing the locking arms on the quick connector while pulling the connector away from the bottom of the alarm. Battery-operated alarms will not have a wire harness.
Professional smoke detector installation costs $50 on the low end and could cost up to $400. The average cost homeowners pay is $115. Smoke detectors are modern-day guardians ready to sound the alarm and save lives, so start your budget here.
When it comes to replacing hardwired smoke detectors, the answer is straightforward: yes, you should have a qualified electrician do the job. While it might be tempting to save a few bucks by doing it yourself, it's not worth the risk.
Some hardwired smoke detectors are designed to work with a specific type of wiring configuration, such as a series or parallel setup. If your existing smoke detectors are wired in a particular way, you'll need to make sure that any new smoke detectors you install are compatible with that configuration.
Although the electrical code doesn't require that hardwired smoke detectors be connected to their own dedicated circuit, it doesn't hurt to install a new circuit to power these detectors. Hardwired detectors are usually installed by splicing into a general lighting circuit or outlet circuit.
Common Causes of Beeping in Hard-Wired Smoke Detectors
Low battery: Even hard-wired smoke alarms have backup batteries that need replacing periodically. A low battery can cause that annoying beeping sound. Dust buildup: Dust and debris inside the smoke detector can trigger false alarms.
Hardwired smoke detectors run on electricity, but they also have a backup battery for power outages. When you hear a hard-wired smoke detector beeping, it means you need to replace its battery.
If your home has hardwire connections, then you should replace the alarms with hardwired smoke alarms of the same manufacturer. You can use a different manufacturer, but this may require an electrician to come in and wire in a different plug (also see the interconnection section below).
Excessive dust buildup can trigger false alarms, causing the system to go off randomly. Clean the interior of the detector thoroughly to resolve this issue. Before taking this step, be sure to turn off the detector at the circuit box to stay safe during the cleaning process.
Disconnect each smoke alarm.
Repeat this for every unit. Many user manuals instruct you to first shut off the power before attempting to disconnect the plug powering a unit. This may help avoid the risk of shock if there is a problem with the connector or the high-voltage wiring.
The US National Fire Protection Association (NFPA) have issued NFPA Standard 72, National Fire Alarm and Signalling Code, which states that all smoke alarms (including alarms that use 10 year batteries, and those that are hard wired) should be replaced when they are ten years old, or sooner if they don't respond ...
Only qualified electricians should install hardwired smoke alarms.
Sometimes the red light on your smoke detector means nothing is wrong. Many smoke detectors use an LED light to show you that everything's working properly. If your device's on/off button has a stale red light, it likely means the system is working properly.
It may just be dirty, you can blow it out with canned air, but if it continues then replace. If the smoke alarms are over 10 years old, they should be replaced anyway. Clear the active detector by pressing the test button, don't hold it or it will go back into alarm. The red led should return to normal.
