It is toxic to hemoglobic animals (including humans) when encountered in concentrations above about 35 ppm, although it is also produced in normal animal metabolism in low quantities, and is thought to have some normal biological functions. In the atmosphere, it is spatially variable and short lived, having a role in the formation of ground-level ozone.
This standard size portable carbon monoxide (CO) & smoke combination alarm monitors the air for the presence of CO or for a potential fire. The alarm will generate loud sound alarm and accompanied by the flashing red LED light when elevated CO level is detected or there is a potential fire
The alarm will emit four short alarm beeps when Carbon Monoxide is detected and will emit continuous beeps when smoke is detected. The alarm will also emit continuous beeps when both smoke and carbon monoxide are detected at the same time
Test/Reset Button - Tests unit's electronic circuitry and horn and resets the unit during alarm; Digital display shows the level of carbon monoxide the unit is sensing
Alarm Memory Peak Level Button - Displays the peak CO level recorded by the alarm since it was last reset or unplugged
Flexible placement for universal safety application: such as installation for rv, travel trailer, boat, , home, house, natural gas detection, truck, car, garage, bathroom, kitchen area, household, office, warehouse, etc...
Green LED: The green LED flashes every 30 seconds to indicate the unit is operating properly.
Red LED: When a dangerous level of carbon monoxide is detected and a potential fire is
detected, the red LED will flash and the alarm pattern will sound.

1x Carbon Monoxide Detector + Smoke Fire Alarm - Combo CO Detector & Smoke Sensor Alarm Sound Photoelectric Tester, Battery Operated with Digital Display for CO Level (White)
A smoke detector is a device that senses smoke, typically as an indicator of fire. Commercial security devices issue a signal to a fire alarm control panel as part of a fire alarm system, while household smoke detectors, also known as smoke alarms, generally issue a local audible or visual alarm from the detector itself. Smoke can be detected either optically (photoelectric) or by physical process (ionization) method. Sensitive alarms can be used to detect, and thus deter, smoking in areas where it is banned.|Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is slightly less dense than air.
