Frequently Asked Questions

Who do you help?

The TN Smoke Detector Guy provides smoke and Carbon Monoxide (CO) detectors for residential homes, churches, and small businesses.

My detectors are old, when do I need to buy new ones?

Per most major manufactures, detectors should be replaced every 10 years maximum from their production date. When a detector is close to 10 years old, false alarms and the low battery chirp can occur, even if a new battery is in the unit.

What types of detectors are available?

Smoke and Carbon Monoxide detectors are available as hardwired, battery, and wireless. The correct one for your home will be dependent on the layout, infrastructure, and environment of your home.

If I have to replace one detector, should I replace them all?

Yes. Often times when replacing a single detector, adding it to a group of older units can cause problems - even if it is the same make and model detector. This is due to newer hardware in each detector. The common problems seen are false alarms, as well as, detectors not communicating with each other.

How often should I replace the batteries in my detectors?

Depending on what kind of battery your detectors use, it could be as frequent as annually to once every 5 years. This is dependent on the detector make and model and battery type required.

How often should I test my smoke detectors?

The best time to test your smoke detectors is when you change your clocks for Daylight Savings Time.

How many smoke detectors should I have in my home?

Most manufactures and the Nation Fire Protection Association (NFPA) suggest placing one smoke detector in each bedroom. Additionally, there should be one detector between your kitchen and sleeping areas, or every 40 feet.

Be sure to consult with your city on their buidling codes, as these vary.
