Combination Smoke and Carbon Monoxide Detector - Composite Alarm with Audible Warning and Digital Display - Battery Powered

describe

This type of smoke and carbon monoxide detector uses electrochemical carbon monoxide sensors, which are the most accurate carbon monoxide sensors currently available. Compared with ordinary electrochemical technology, the latter technology has higher accuracy, lower power consumption and longer service life. The battery smoke detector is suitable for indoor places such as villas, factories, shopping malls, warehouses, office buildings, etc.

function

-New 2-in-1 smoke and carbon monoxide detectors. High-precision electrochemical sensor (the most accurate CO sensor). Infrared photoelectric sensor (the best sensor for detecting smoke while minimizing false alarms)

-Low power consumption design: After installing 3 batteries (3 x 1.5V AA batteries, the package does not include batteries), you can hear the DI sound and start working normally after 2 minutes. During operation, it does not display any power-saving design. Long standby time and low power consumption.

-Loud alarm: Press the "test" button, the smoke detector and carbon monoxide alarm are ≥ 85 dB, whether you are sleeping in the bedroom or watching TV downstairs, the sound is enough to remind you of the danger.< /p>

-Easy to install: Drill two marked installation holes. Use a hammer to tap two plastic grommets into the holes. Install the bracket to the ceiling by inserting and tightening the provided screws into the plastic grommets.
