Extra loud alarm should easily wake even the heaviest sleeper.

great alarm - 01/04/2015
Reviewer: scubado
This alarm probably saved my house as we had a gas leak in a hidden pipe after a furnace was installed! my wife has no sense of smell so she cannot detect gas! the alarm went off at 3 am and woke us up, a call to the gas company sent an inspector out and he found 4 leaks! alarm paid for itself!

Good Alarm one feature not working - 07/31/2014
Reviewer: Kyle
The alarm appears to work fine. I tried the remote feature with multiple different remotes. The unit did not respond. Not really a deal breaker, but it says that it is supposed to work but doesnt on my unit

We moved our washer and gas dryer into a closet on the first floor. I installed this alarm near that closet as a preventative in the event the gas piping or gas dryer leaks natural gas into that area.

Gas safety - 07/18/2011
Reviewer: HENRY DWYER
I rated this unit good, but dont really have anything to compare it to - might be very good. But propane, natural gas methane and CO sensing and alarm all in one unit - what a deal! Setup is easy, and with the backup battery we dont get thrown out of bed when the power cycles off. Somehow the fact that this is primarily AC powered escaped notice when ordered, but with the battery backup, not a problem. Be aware, as with all gas detectors, it has a 5-year end-of-life. But this is a good thing - the prior generation of CO detectors where not smart enough to tell you when they could no longer be relied upon. Our mounting retains the AC adapter inside the unit since we want it low to the floor for propane alerts, but I would be a little concerned in you would have to mount it at a distance from your AC, since the DC cable from the AC adapter to the unit is very small gauge and seems as if it could be cut easily.

Your lead times seem to be variable which has caused us some problems. Plus some of your specials have a lower price than our wholesale cost. We should automatically be give the lowest price available. Cindy does a great job.

CO and gas alarm - 04/11/2011
Reviewer: William Miller
The item was easy to install and looks nice. It is loud enough to hear through the bedroom doors and loud enough to scare you out of bedd if the door is open.

Works Well - 09/05/2009
Reviewer: Jim Carry
I looked at other models before purchasing and this one seems to pack the most detection functions into one unit. Upon arrival it was very easy to install in my basement. I give it 5 stars!

Q: How do I get my carbon monoxide alarm to stop chirping?

A: If your carbon monoxide alarm keeps chirping, the battery may be low or weak. On First Alert carbon monoxide detectors, check to see if the battery light is yellow or green. If the alarm is chirping and the light is yellow, it means the battery is low. The way to get a carbon monoxide alarm to stop chirping is to replace the battery.

Q: Where should I install carbon monoxide alarms? What is proper carbon monoxide alarm placement?

A: It is very important to install carbon monoxide alarms near or in each separate sleeping area. Many states now require that a carbon monoxide alarm is placed in each bedroom. For added protection, placement of an additional carbon monoxide alarm at least 15-20 feet away from the furnace or fuel burning heat sources is recommended. Also, install carbon monoxide alarms at least 10 feet from sources of humidity like bathrooms and showers. In two story houses, install one carbon monoxide alarm on each level of the home. If you have a basement, carbon monoxide alarm placement is recommended at the top of the basement stairs.

---

Q: Is there anywhere I shouldn't install carbon monoxide alarms?

A: Do not install carbon monoxide alarms in garages, kitchens, furnace rooms, or in any extremely dusty, dirty, humid, or greasy areas. Do not install alarms in direct sunlight, or areas subjected to temperature extremes. These include unconditioned crawl spaces, unfinished attics, un-insulated or poorly insulated ceilings, and porches. Carbon monoxide alarms should not be installed in outlets covered by curtains or other obstructions. Do not install in turbulent air-near ceiling fans, heat vents, air conditioners, fresh air returns, or open windows. Blowing air may prevent carbon monoxide from reaching the CO sensors.

---

Q: How many carbon monoxide alarms should I have in my home?

A: So how many carbon monoxide alarms should you have in your home? The National Fire Protection Association (NFPA) recommends that you should have a carbon monoxide alarm centrally located outside of each separate sleeping area in the immediate vicinity of the bedroom. For added protection, you should have additional carbon monoxide alarms in each separate bedroom and on every level of your house, including the basement. Some states now require that you have a carbon monoxide alarm in each bedroom of the house. If you install only one carbon monoxide alarm in your home, place it near or in your bedroom.

---

Q: What is the proper way to do a carbon monoxide alarm test?

A: The following procedure is the proper way to do a carbon monoxide alarm test - Press and hold the Test Button on the front of the alarm until the alarm sounds. Be sure you hold the button down long enough; it can take up to 20 seconds for the alarm to respond to the test.

---

Q: Is it a false alarm when my carbon monoxide alarm sounds and there doesn't seem to be a problem?

A: A carbon monoxide alarm false alarm should not occur if your alarm is in working order. Remember, carbon monoxide is an odorless, colorless gas. If your carbon monoxide alarm went off, it detected potentially harmful amounts of carbon monoxide. After the professionals have evaluated the situation, make sure no one has any symptoms of carbon monoxide poisoning.

Here are a few situations that may cause a carbon monoxide alarm "false alarm:"

• The carbon monoxide alarm needs to be relocated. Carbon monoxide alarms should be located 15-20 feet away from all fossil fuel burning sources like furnaces and stoves. Alarms should be located 10 feet away from sources of humidity like showers.
• Fossil fuel burning appliances may not be burning fuel completely. Check pilot lights/flames for blue color. Appearance of yellow or orange flames indicates incomplete combustion-a source of carbon monoxide.
