Product description

Combination Smoke and Carbon Monoxide Detector

The carbon monoxide detectors/smoke alarm is used for detecting both smoke and poisonous gas—carbon monoxide.The product uses high sensitivity photoelectric sensor to detect smoke and high stability electrochemical co sensor to detect carbon monoxide.

Dual High Stability Sensors

High quality and high stability sensors, responsive and reduce false positivesCO Alarm sensitivity:

70 PPM -> 60~ mins

100 PPM -> 10~ mins

400 PPM -> 4~ mins

700 PPM -> 2~ mins

Note: Strictly follow the UL2034 standard requirements to protect people’s life safety

LCD Display + LED Indicator

Once your living places have carbon monoxide or smoke, and one of them reaches its alarm sensitivity, it will give out both sound alarm and LED indication to warn.

LCD displays the concentration valueLED light indicates the working status

Easy to Install

The carbon monoxide detectors and smoke detector are widely used in indoor places where it release carbon monoxide or easily catch a fire.

Recommend the installation of a carbon monoxide detectors/smoke alarm in the following locations:

on each level of a multilevel homeat both ends of bedroom hallwayon the ceiling in the center of the roomon the wall, 4”~ 12”below the ceiling
