Are Your Smoke Detectors Up to Code? The 10-Year Rule for SC Homes
We all know that smoke detectors save lives. But did you know that they have an expiration date? A smoke detector that's more than 10 years old is no longer considered reliable and may fail to alert you during a fire. This "10-year rule" is a critical part of modern fire safety codes in South Carolina.
## Why Do Smoke Detectors Expire?
Over time, the electronic sensors inside a smoke detector degrade. Dust, humidity, and simple aging cause them to become less sensitive. After a decade, the unit can no longer be trusted to function correctly in an emergency.
## How to Check Your Detectors
- Check the Date: Carefully twist the smoke detector to remove it from its mounting bracket. On the back, you'll find a label with the date of manufacture. If it's more than 10 years old, it needs to be replaced immediately.
- Test Monthly: Press the "TEST" button on every smoke and carbon monoxide (CO) detector in your home at least once a month to ensure the alarm sounds.
- Replace Batteries: Replace the batteries in all your units at least once a year. A great time to do this is when the clocks change for Daylight Saving Time.
## Modern Upgrades for Complete Protection
If your detectors are due for replacement, consider these modern upgrades:
- Interconnected Alarms: When one alarm sounds, they all sound. This is a crucial feature for larger homes, ensuring everyone is alerted no matter where the fire starts.
- 10-Year Sealed Batteries: Many new models come with a sealed lithium battery that lasts for the full 10-year lifespan of the alarm. No more annoying 3 AM chirps!
- Combination Smoke & CO Detectors: These units offer dual protection from both fire and carbon monoxide, a dangerous invisible gas.
As licensed electricians, we can install a fully interconnected, hardwired system of smoke and CO detectors that provides the ultimate level of protection for your home and family.
