Frequently Asked Questions
About Smoke Detectors

If your smoke detector is chirping intermittently, it's usually a sign the battery needs replacing. However, if this doesn't solve the issue, contact Detector Checker for help! Our experts will diagnose and fix any problems with your smoke detectors to keep them working properly.

We recommend replacing your smoke detector batteries at least once a year. It's also good practice to clean them at the same time. Detector Checker provides all these services, including battery replacement, testing, and cleaning.

According to the National Fire Protection Association (NFPA) and Underwriters Laboratories (UL), smoke detectors need replacing after their recommended lifespan, typically every ten years. Detectors can lose effectiveness over time, with a potential 30% failure rate after a decade.

If you're unsure about the age or condition of your smoke detectors, contact us for a professional evaluation and advice.

While it depends on the number of bedrooms and levels in your home, the law requires one detector in each advertised bedroom, and one on every level. Contact Detector Checker for personalized advice!

There are two main types of smoke detectors: ionization and photoelectric. Each type is suitable for different kinds of fires:

• Ionization smoke detectors: These detectors are more responsive to flaming fires. They're sensitive to small particles produced in fast-moving fires such as kitchen or garage fires.
• Photoelectric smoke detectors: These detectors are better for smoldering, slow-burning fires like those involving furniture.

For maximum safety, we suggest using a dual-sensor smoke detector that combines both types for detecting all kinds of fires.
