Carbon Monoxide Detector Alarm for home security

   Carbon monoxide (CO) poses an invisible threat. It's a colorless, odorless gas produced by any fuel-burning appliance or fixture — such as a furnace, water heater or fireplace. Carbon monoxide can build up in the home from malfunctions or improper venting in these devices. It can also accumulate if the home is sealed for energy efficiency, reducing the exchange of inside and outside air. An attached garage in which a vehicle is running can also allow carbon monoxide to enter the home. The gas is dangerous because it replaces the oxygen in the air and, when inhaled, creates a toxic compound in your body.

  Carbon monoxide alarms is a tool that can help you protect your home and family from these threats, even when it occurs in remote areas of the home or at night when everyone is asleep. You can purchase the devices separately or as combination units.
