Dangers of carbon monoxide
Every year, hundreds of people are killed and countless more are injured by carbon monoxide poisoning. Find out more about the dangers of carbon monoxide.
Why use carbon monoxide detectors in your home?
Carbon monoxide is odorless, tasteless and colorless. You cannot detect it on your own. For your own safety and that of your loved ones, carbon monoxide detectors are vital.
Gray Security Services recommends the UltraGuard carbon monoxide (CO) detector and alarm.
- UL-approved (UL2034 and UL2075 listed)
- Powerful siren (85 dB at 10 feet)
- 99% accuracy rate keeps your family safe without false alarms
- Continuously self tests every 10 minutes to ensure it's working
- Five year limited warranty

The International Association of Fire Chiefs recommend a carbon monoxide detector on every floor of your home, including the basement. A detector should be located within 10 feet of each bedroom door and there should be one near or over any attached garage. Each detector should be replaced every five to six years.
