I bought two of these detectors, I am wondering how you can tell if they work? They both read zero. Gas logs burning on high, near gas furnace and 0??

Try sticking it directly over a gas fire and hitting the button. It should display a number

Put it in a ziplock bag, blow some smoke in the bag (cigarette, etc), and close bag and wait. Should see a reading on LCD and eventually the alarm will sound)

Mine came with no instructions, no one listed as a manufacturer. First batteries lasted 3 months, Unit chirped, read 93, don't know what that meant, replaced batteries and put on wall. I am surprised that Amazon would sell such a non-discript device.

I had the same 2 wires on my old thermostat, and I found the answer in one of the responses to a review that was already on the site, by A. Pico: "I was in the same situation: two unmarked wires that when connected turn the furnace on. Simple. However, in my case, the trick was to connect them to positions R and W." Mine worked when I connected them to R and W also; does not matter which goes to which, and I did not take off any jumpers.

I have two of these detectors and have had no false alarms. There may be other "gases" that trigger the alarm, such as hair spray, disinfectants or other aerosol can contents. The alarm works good for us.

I had this happen twice shortly after my home was constructed and everything was new and I'd moved in. The alarm turned itself off at after 30 seconds. The only thing I could think of is that something new was "outgassing" (paint, plywood glue, etc.). Just to be sure, call your alarm company or an installer of smoke alarms to see if one of your sensors units has gone bad.

Not sure about the question. My detector was returned as it was defective as it kept saying 'service required'. I do not recommend this device or the company.

Hello, no this does not display the current CO2 level in the house. Mine has never detected has but it has a test button and the alarm is audible throughout my entire house (1700 sq ft.). There is a constant green light on and dashes across the screen indicating it is on. The unit comes with an instruction booklet that explains the display and what to do if the device goes off. We have a gas furnace and it's peace of mind to have this. I live in Oklahoma and just recently a house exploded from a gas leak. This would undoubtedly warn me if levels rose that high so that myself and proper authorities could take action.

I'm assuming that the blower is not coming on both before and after you replaced the control board. Ensure the jumpers are in the correct configuration and there is power to the board. Test the motor by directly connecting it to 120VAC. If the motor works, the board is installed correctly and it has power then the next thing to check would be the plenum temperature sensor. That is the "enable" for the motor. Does the gas burner come on for a while and then shut off?

Using compressed air, blow out the alarm. Test your battery, it may be low. Dust will accumulate around the sensor. If these suggesting don't work, you may have a faulty detector.

Google the sensor and display to find the instructions. I seem to recall that there's a jumper on the circuit board that you need to set for one or two temp sensors. So I'd take a look at the docs before I gave up.

The one I purchased works fine. It does have a very sensitive motion sensor with a wide angle. Check to see if there is any moving object within the swath of the detector.

The only way to find out for sure would be to "smoke" test it, if your smoke detector beeps, you (had) a problem.I'm sure it would become a fuse rather than an ammeter well below 30A.It is a good idea to use a fast-acting fuse of the same (or slightly higher) value as your ammeter in series with the shunt resistor. NOT IN THE SHUNT TO METER LEADS

Like another commenter I found that the batteries only lasted a week or so when used in conjunction with Z-wave/SmartThings controller without a "C" wire. When the batteries die the thermostat stops sending any signal to boiler so you better hope it's not below freezing and/or that someone is around to change them. I now have "C" wire connected and all is well so far.

I was getting all kinds of funky readings with mine before it fried. It was really the first time that I was checking a house of arc fault. Anyway after it burnt up i talked with tech support they don't have anything. And they told me that you can get many false readings. I won't be replacing it with the same thing

This is not a data logger. It only tells you the high and low since the last reset. There is a reset button on the back. It is very useful to monitor the high/low in a given area. I use mine to make sure my boat engine compartment engine heater is working in the winter. I can are how cold it got when I was away. If it never reads below 40 then I know the heater is working as it should.

What kind of meter are you using. I have gas meter for measuring inches of water column. If that's what you have then No everything should read 0 if there is no gas pressure

Get a new smoke detector. They get dusty with age and dust sets them off. I hate them

Hello, I have no idea, was just curious about the item and thought I could use it to possibly track down a wall switch that goes nowhere in our house. turn off all breakers but the circuit the switch is on and check for a signal thru the wall with the switch on and follow it, have not tried yet. Just checked around a few wires and it does sense the electricity. I think the deal on it detecting cameras is that you can see the infrared with it or something. Have not had time to really check, it may just be a barely useful gimmick. But I hope I can trace the wire. It may make a cool kinda selective sensitivity signal tracer.Peace!
