Carbon Monoxide Electrochemical Sensors

I read the info on your web site and I’m very interested, but have one question.
The warranty for your model 2004 product is 1 year (limited).  Who makes the carbon monoxide electrochemical sensor and what is that manufacturers’ warranty [for the life of its sensor] to your company?  In other words, how long does the sensor manufacturer say their sensor should last?

I don’t think the US CO home alarm manufacturers set out with the idea of deceiving the public, but their advertising certainly confuses them.  I don’t think UL/CSA or NFPA set out to establish a manufacturing standard that is less protective than it could be.  They just started out with the sole idea of home fire protection and set up a manufacturing requirement for CO alarms that were meant to be used in conjunction with smoke alarms.

I think the idea for your product is great and long overdue. It’s time for a product like yours that IS designed to protect against low level CO.

May I suggest that you seek an endorsement and/or support from the American Industrial Hygiene Association and/or the National Safety Council?


Thank You, for your comments and question.
I have attached the “Link” to the Sensor Manufacturer’s INFO Sheet on the C  O Sensor I use in my C  O – Experts Low Level C  O “Health” Monitor. You will notice that their Warranty is 7 years, and the “Expected Life” is 10 years.

While it is true that MY “Initial Interest” in C  O back in 1968 was a result of the Carbon Monoxide factor in Fire Deaths, that is NOT the case with the writing of UL-2034.

Please keep in mind that NO STANDARD is EVER written unless a Company has a Product to SELL ! ! !

I have been involved in Early Warning Detection Products for 51 years, and involved in the “Standards Process” since back in the 60’s. The “Technical Committee Members” ALWAYS include a large percentage of product and component manufactures that have a “Vested Interest” in being able to seek “Mandatory USE” of the product involved, [assuring a larger  volume of Sales], … which means that a “STANDARD” to Validate the “Performance” of said product, is a Great Asset.

The PRIMARY PURPOSE of UL-2034 was / is, to help the “Listed” manufacturers SELL their products, NOT for overall Consumer Protection, as I believe that this fact is VERY Evident in the “Wording” of the UL “SCOPE” for UL-2034:

The Total LACK of Protection from Chronic Low Level C  O Poisoning is EASY to understand when you consider Item 1.2.1 of the Scope statement of UL-2034:
“Carbon monoxide alarms covered by this standard are not intended to alarm when exposed to long term, low level carbon monoxide exposures or slightly higher short term transient carbon monoxide exposures, possibly caused by air pollution and/ or properly installed/maintained fuel-fired appliances and fireplaces. See Table 38.1, Part B, False alarm resistance specifications.”

[ Table 38.1.B indicates the “NO ALARM” or “Ignore” Levels: 30 PPM for 30 days, 60 minutes @ 70 PPM, 10 minutes @ 150 PPM, and 4 minutes @ 400 PPM.]  [In my opinion, the worst part of this limitation is that depending on how the alarm’s sensitivity is calibrated, you “Could” be exposed to as much as 69 PPM … FOREVER” !]

Thank You, for your Comments about my C  O – Experts Low Level C  O “Health” Monitor, it is TRULY NEEDED in EVERY Home.

Thanks for your reply.  You’re completely right – no standard is ever written except to benefit a company with a product.  There are good things about US capitalism and some not so good.  I’m a convert….my wife will probably buy 3 of your monitors next week.
