    CO Detectprs

    Kidde makes one that gives a constant digital readout that is not expensive. I've sen them at Sears, Servistar, True Value, Home Depot, Lowes, etc.

    UL 2034 approved CO alarms

    Ken, with all due respect, trust me, Kidde and all the other manufacturers who have their alarms approved by UL only provide minimal protection - if any at all.

    Go to www.coexperts.com and pull up the GRI report on the "Performance and Reliability of CO Alarms". One of the conclusions in the report states that the digital readouts of UL approved alarms "seemingly display random numbers"!!!!!

    I have seen this over and over again. I use a Kidde Nighthawk to show the difference between a UL 2034 alarm and a NCI or CO Experts alarm (which are not UL approved). I put them both in a plastic bag and blow it up with 100ppm CO (Calibration gas). The NCI and CO-Experts alarm generally under 5 minutes, the Nighthawk usually takes between 4 to 6 hours - if at all..... And when I hit the recall button on the Nighthawk it has displayed as low as 2ppm and as high as 34 ppm (with 100 ppm cal gas).

    I was involved in a news segment last spring where the news station went out and purchased 8 alarms off hardware store shelves. We put them behind the tailpipe of an automobile that a test instrument was showing over 2000ppm in the exhaust. Out of the 8 only 5 alarmed.

    This is right in line with the GRI report. They found that 38% of the alarms they purchased, failed, brand new right out of the box. And when the test button was pushed on those that failed, all indications were that the alarm was functioning OK - because all UL requires of the 'test' button is that the buzzer is working.....

    The news station was doing the segment because of an incident where a 14 year old girl died due to CO exposure - and there was a UL approved alarm in the home.....

    Here is the link to the GRI report:
    If you want to wade through it, the message is there, but, again, trust me, it ain't pretty.....

    cheap co alarm

    If you want cheap get a parakeet. I had a customer with a bad water heater that killed theirs. The Kiddie death detector alarmed the next morning. You get what you pay for. FACT.
