Monitor to use along with gas fireplace

Simple and effective

Would Recommend

Installed in basement near ceiling as instructions specify. Real testing was a bit tricky, left it on unlit stove on lowest setting to get a real alarm test. It tries not to throw false alarms so it had to run for about 10 sec before triggering. Other testing of quick burst of higher amounts of gas did not trip it.

Template is wrong. So frustrating

Would Not Recommend

The instructions have a template for mounting screws which you would think is helpful. It would have been better without the template. The text says the mounting holes are 3 7/8 inches apart. The template hole locations are 3 13/16 inches apart. The actual spacing of the holes are 3 15/16 apart. The 1/8 inch difference between the template and the detector means it does not fit. It also means you need to repair the wall before re-mounting as you can't move a wall anchor 1/8 of an inch. Fix ...

Reliable plug in carbon dioxide monitor

Would Recommend

Great monitor. My previous monitor was just like this one, same model/brand lasted 5 years. No problems. I like that it is a plug in with a 9v battery back up in case you have an electrical outage. You can’t go wrong ordering this one.

Easy Install and Double Sensor is a Plus

Would Recommend

Easy install. It's Firat Alert. Needed something in our Furnace and Water heater room where the only place gas is present. This fit the bill. It is plugged in and has a battery back-up with a Duracell Coppertop 9V battery included. Has test button that tests and shows a numerical display for Gas and CO. Nice looking and well made. Green indicator light shows unit is on and power supplied.
