Works okay

21 days ago

Purchased this unit to replace an existing unit that seemed to be malfunctioning, but after further investigation really only needed the backup battery replaced. The new unit works fine, but the little display screen isn’t as nice as the one on the old unit. You need to get very close to read the display, whereas with the older unit you could read 0ppm of CO from across the room no problem.

Q: Will this read the carbon monoxide in the air or must alarm if levels get high enough for a longer period of time

2 years ago

1 Answer

A: Our CO alarms must meet CSA 6.19 which has alarms sounding in this manner: at 70 ppm it must sound within 60 to 240 minutes of constant exposure. At 150 ppm sound within 15 to 50 minutes and at 400 ppm, 5 to 15 minutes. The alarm simulates the absorption rate of the human body.
