Keep your family safe with the Safety Siren combination gas detector. The model # HS80504 protects your home and family from dangerous levels of Carbon Monoxide (often referred to as “The Silent Killer” because it is odorless, tasteless and colorless), in addition to Methane (Natural Gas), and Propane, the most common combustible gases found in the residential environment. Simply plug into any 110-volt wall socket and live with the confidence that your living quarters have an added level of protection from catastrophic gas leaks

Inexpensive insurance.,
This unit is small, inexpensive, and easy to install. Our gas company tested it and it works very well. The alarm could be a little louder but other than that I have to say it does the job of units costing three times as much and there is no wiring or difficult installation requirements. Just plug it in and it is working. Doesn’t get much easier than that.

|Not compliant with any current UL safety standard,
I was disappointed to find that this U.S. manufacturer is actually
selling gas alarms that don’t address current safety standards.
Specifically, I found that the product manual does not say it is
UL-listed for any relevant Underwriters Laboratories standards, and
when I checked the UL product database I could not find listings for
this product for either explosive gas (UL 1484) or carbon monoxide (UL
2034).
In the case of explosive gas (UL 1484), this product is not UL-listed
though it appears to be compliant in the loose sense that it alarms at
the standard set point of 25{fa0f407a56ebf26e8755ec9e145523374db89e13015bb27dc750b111d8cc035c} LEL. While other products in this
product line are UL-listed, this one is not, suggesting that the
manufacturer simply doesn’t care enough to pay for the appropriate
testing/listing for all of their products.
In the case of carbon monoxide (UL 2034), this product is not
UL-listed and indeed has definitely NOT been compliant with UL
standards for over a decade. The original standard (UL 2034-1992)
specified CO alarm set points at 100ppm(90min), 200ppm(35min), and
400ppm(15min) and these are indeed the alarm points listed in the
product manual (which is dated 1996). In 1998, UL updated the CO
alarm set points to 70ppm(240min), 150ppm(50min), and 400ppm(15min).
But the manual says quite clearly: “This detector has not been
investigated for carbon monoxide detection below 100ppm.”
Given the note about calibration that is also contained in the product
manual (“CO sensor calibrated at 200ppm CO specific to avoid false
alarms”) one gets the sense that this is a product for people who care
about buying products that won’t wake them up with false alarms as
opposed to people who care about safety standards of the current
century. The similar Kidde and First Alert products are UL-listed and
people complain about more false alarms. You pays your money and you
takes your choice.

|Very fast,
After my wife bumped a burner knob on our gas range and fell asleep while the house filled with gas, I ordered this alarm overnight. I have it plugged in near the stove. It alarms in seconds if a burner is on but not lit and has never given a false alarm.
