  • Our detector is uniquely designed to be very small, almost half the size of others. We believe a security device should be unobtrusive and blend seamlessly with your home's aesthetics. Additionally, it is available in both white and black for you.

  • For optimal protection, install the CO detector on every level of your home, especially near sleeping areas. It's also recommended to place one near fuel-burning appliances and in any room with a furnace or fireplace.

  • Our CO alarm is compact and slim, neat and tidy, very easy to use and install. It features a 10-year-sealed battery, and alarm 10 year life. It will be safeguarding you and your family for 10 years. It's reliable, portable, simple and long lasting.
