WILL THIS UNIT ALARM WITH A PROPANE LEAK,? AS PROPANE IS A HYDROCARBON-- ARE THERE UNITS THAT DETECT PROPANE ONLY?
Asked by: ROCK
I emailed the company and asked the same question and this is what they had to say "The reason there is no information in the literature regarding propane detection is because the unit does not detect propane. As you have stated, the unit detects carbon monoxide and natural gas. The manual provides all the information needed pertaining what it detects in the manual." It's also unclear what gas levels it is required to engage the alarm. The literature states that "the typical level for detection of the gas is 25% of the lower explosion limit (LEL)" and not measured in PPM. You are better off getting carbon monoxide detector and explosive gas alarms separately.

Rated 2 out of 5 by from so so purchase I bought two of these units. they plug into a wall but have a 9 volt battery in side for backup. You have to pull out a tab to connect the nine volt. One unit I plugged into the wall, 12 feet from my stove and I believe it is working. The other one I plugged into 4 outlets through out the house and it was always going off , even in a bathroom witht the window open. I unplugged it and set it on my pool table and it still kept going off until I unplugged the 9 volt battery. I am returning it and hoping the next one works
