After this brown out, we have had a few cases co poisoning in my area.
I checked the furnace today and my filter was upside down side ways in it.
I just got a couple new co detectors and these badges that I can stick in the suspected area to check levels.
Anyone used these before?
Any tips?
Thanks



Answer
The most common cause of CO is related to vent problems-i.e. cracked or plugged vent piping. A furnace can also create CO if the internal heat chamber is cracked.

Difference between carbon monoxide alarm and low battery alarm?




Mike


I have a battery powered carbon monoxide alarm that started beeping a hour ago, but then stopped when I replaced the batteries.


Answer
Carbon monoxide (CO) alarm is triggered to sound, if it detects the presence of the carbon monoxide (CO) gas, a colorless and odorless compound produced by incomplete combustion, in order to prevent carbon monoxide poisoning. CO detectors detect and warn people about dangerous CO buildup caused, for example, by a malfunctioning fuel-burning device. In the home, some common sources of CO include open flames, space heaters, water heaters, blocked chimneys or running a car inside a garage.

While a Low battery alarm is triggered to sound, if the circuit detects that a battery power supply falls below the specified rating to run the detector device.

If your device have both the alarm you must distinguished the tone of Carbon monoxide alarm to the tone of Low battery alarm. Usually they are of different tones to differentiate them from one another.

In your case maybe the device had detected the presence of CO gas while in its position and triggered its alarm. But when you remove it from its place the CO gas had fade and blow away to the air and stop beeping. Thinking that it is a low battery you replaced it without testing the battery if it is really a low batt. All gas detector has a "Test Button", the test button on a CO alarm only tests the battery and circuitry not the CO gas sensor.
