Do Hardwired Smoke Detectors Have Batteries?

A smoke detector is one of the most important safety devices inside your home. Properly working smoke detectors are crucial. If you are wondering if hardwired smoke detectors come with backup batteries, the answer is yes.

Do Hardwired Smoke Detectors Have Backup Batteries?

Hardwired smoke detectors that are attached to a home’s electrical system do feature backup batteries to sound the alarm even in the event the power goes out. In this case, you do need to change the batteries when the unit indicates it is low on power. This helps to offer continued protection from smoke and fires.

Types Of Smoke Detectors

Both wired and battery-operated smoke detectors will come in two types: ionization or photoelectric. A photoelectric or smoke alarm can detect a fire, while ionization or heat alarms respond better to active flames.

A combination detector is another type of smoke alarm that is not as popular. This unit can detect smoke, flames, and carbon monoxide. They can also be connected with other smoke detectors, providing whole-house coverage.

Pros Of Hardwired Smoke Detectors

• The first pro is that homeowners won’t have to constantly change batteries. Hardwired smoke detectors are working as long as your home has power.
• You will only have to change out detectors once every ten years.
• These detectors do not feature that annoying, chirping sound commonly heard from battery-powered alarms.
• They are safer than battery-powered detectors because they are interconnected throughout the home.

Cons Of Hardwired Smoke Detectors

• The installation process is much tougher with hardwired units. Unless you have extensive electrical knowledge, you will need a professional electrician for this task.
• These detectors are slightly more prone to false alarms. Most units will self-test after 12 hours and if there is any faulty wiring, it can cause issues.

What Happens When A Detector Keeps Beeping?

Hardwired smoke detectors are typically best for homeowners. However, at times they can begin chirping or beeping. Only the backup unit will chirp when a battery needs to be replaced. Simply remove and replace said battery unless the detector is sealed with a 10-year battery. In this event, you’ll have to replace the smoke detector.

How Long Do Smoke Detectors Last?

On average, smoke detectors are designed to last between 7-10 years total. At that point, they will need to be replaced. Some smoke detectors will warn users that they are dying. The smoke detector may beep five times rapidly, pause and then repeat this pattern.

Turn off the power at this time, remove the smoke detector and replace it with a new one prior to restoring power. Make sure to pull out the battery tab or your unit will beep until the backup battery is installed properly. Another tip to prevent any beeping is to ensure the cover or battery tray are closed fully.
