## Questions & Answers

**Q: Has anyone found out why this detector drains the battery within hours even if it's a brand new battery and it's plugged into the wall?**
A: No.  But the company denies there is a problem.  If your unit is within the warranty period, they will replace it with another one that drains the battery.  Then they deny there is a problem.

**Q: Does this unit works for LP propane gas leak**
A: I had a major lp gas leak in the gas line inside my walls and this unit never registered anything. Don't waste your money. Fortunately, I believed what I thought I smelled and called the gas company.

**Q: Has anyone had false alarms? My alarm which is s couple. Of years. Old went off saying GAS but there was no trace of gas in the house.**
A: I cannot plug mine in anymore it immediately alerts “GAS”.  Very disappointing.  It’s only a couple years old.  I would expect for his price they last longer and/or have a better return policy.

**Q: We have an enclosed garage that is more of a "play room."  Can I install this unit in a garage?  The Kiddie Alarms state you can't use them in a garag**
A: A running internal combustion engine, which powers all cars (except the new battery powered ones), produces deadly carbon monoxide gas.  I would not install this detector in a garage used for its normal function of housing the family car because the presence of carbon monoxide created when entering and exiting the garage would defeat the purpose of the detector.  Use of charcoal for grilling food also creates carbon monoxide gas.  IF cars, lawn mowers, and other gasoline powered engines are never operated for even short periods of time in the garage, and use of charcoal for grilling food never occurs in or near the doors to the garage, then I would see no reason not to install this detector there, because the garage is being used more as a housing location instead of a car storage/workshop area.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Seems to wok fine.
*by R***Y on September 4, 2024*

I picked this detector because it covered all the bases for various gasses and has an outboard power supply. This let me mount it in an ideal location then pass the wire through the wall to an outlet in a closet for a clean install. I can't speak to actual functionality since I hope it never goes off, but I've had no false alarms.

### ⭐⭐⭐⭐⭐ Ease of use
*by W***I on July 24, 2025*

This is a really loud alarm. All you need to do is putting in batteries and plugging into the outlet. It doesn’t need to change battery for really long time. This is a great reliable detector for my basement. There is instructions printed on the device, so you don’t have to look up what to while it beeps loudly to your ears.

### ⭐⭐⭐⭐⭐ Glad I had this detector
*by D***H on June 18, 2015*

Bought one of these 9 years ago. About a month ago I woke one morning and this thing was going off. The display said "Gas". I went to every room in the house including the attic and smelled nothing. I kept resetting the detector moving it from room to room and it kept going off. Called the fire department. They checked my house and attic and found nothing. They told me it was 9 years old and may be defective. But since I called them, they had to call the gas company. They came out and had a real sensitive sniffing machine. Found nothing in the house. But in the attic found a tiny leak on a pipe union that you could not smell standing right there. This detector did its job! A few days ago it starting giving 3 short beeps every minute. That means it needs to be serviced. Well, I decided to throw it away and buy a new one. No telling how long we could have lived in our house with gas fumes if we had not owned this detector.
