Installation Height for Carbon Monoxide Alarms Is Your Choice

by Barbara 8. February 2013 10:52

Question about  installation height for most effective use of carbon monoxide alarms

Q:"How high do I need to install carbon monoxide alarms in my home?" Thanks. Rebecca

Answer: According to information from one of our manufacturers, you can install a CO alarm at any height in your home. The reason is that the molecular weight of air is almost identical to the weight of carbon monoxide. Air is typically composed of 78% nitrogen and 21% oxygen. Nitrogen has a specific weight of 28.013 while carbon monoxide is almost identical 28.011. CO mixes with
Air as their weights are approximately the same.

We advise you put the unit high enough that a child cannot tamper with the unit. Also remember that a minimum of 3 carbon monoxide alarms are recommended for a two story home, one on each level near the stairwells. Put one inside each bedroom if you close bedroom doors at night.

Direct plug-in units, CO alarms connected to a 12 or 24 volt security system and 9 volt battery operated ones give you many options.

We prefer the Costar 9RV, a 9 volt battery powered CO alarm that is for homes or recreational vehicles. These easily mount with two screws. The units cannot be reinstalled on the mounts unless there are batteries installed.

For homes with wired security systems, the CoStar Security System Carbon Monoxide Alarm,12-24SIR is a great choice.

Costar carbon monoxide alarms use a unique sensor that mimics red blood cells. Each sensor takes 28 days to "grow." The sensor reacts with carbon monoxide just as red blood cells do in our bodies. In other words, when a human is exposed to CO, the oxygen in the blood that attaches to red blood cells is replaced gradually by carbon monoxide. When carbon monoxide levels in an area near the sensor reach a level of 70 parts per million in a period of 60 to 240 minutes, the sensor is saturated sufficiently to set off an alarm. Below 35 ppm no alarm will sound. At 150 ppm, the alarm goes off within 10 to 50 minutes. At a level of 400 ppm, the alarm sounds within 4 to 12 minutes. 400 ppm alarm within 4 to 15 minutes.

Safe Home also sells RV carbon monoxide alarms that wire to both 12 volt systems, the coach and the engine, and have a 9 volt battery back-up. The CoStar 12RV-DB 12V RV CO Alarm W/9V Battery Backup protects you even if the 12 volt system is disconnected.

We also sell co alarms by other manufacturers that plug directly into 120VAC outlets. The only problem here is that few outlets are above a child's reach.

Thanks for your question.

Sincerely,

Barbara

UL and CSA Require RV CO and Propane Gas Alarms Stop Working in 3-5 Years

by Barbara 28. April 2012 10:03

Question about life span of carbon monoxide and propane monitor/alarms in RV's and trailers.

Q: "My RV has the original carbon monoxide and propane monitors. When should I replace them? Thanks Tom."

Answer: Safe Home recently learned that all newly manufactured 12V propane alarms and carbon monoxide alarms, whether combination alarms or single alarms, must include an internal shut-down system. The Safe-T-Alert brand we sell has an internal warning system that beeps and flashes when the sensor is dying and then beeps and flashes when the unit shuts down from sensor failure. Typical life is 3 to 5 years unless the sensors are exposed to aerosols such as spray deodorants, cooking sprays, cleaners, etc. Note the date of installation on the outside of the unit with a sticker or log into your owner's manual so you won't be awakened in the middle of no where with the bad news that your units are or have failed.

Below is the information we received from Safe-T-Alert in April 2012 to share with customers.

CARBON MONOXIDE & PROPANE ALARM REPLACEMENT NOTICE: Note to Customers:

All Safe-T-Alert Propane and Carbon Monoxide Alarms that are 5 years old and older are beyond their Mandatory Replacement Time and MUST be replaced.

Background: Underwriters’ Laboratories (UL®) Carbon Monoxide Standard UL 2034 and Canadian Standards Association (CSA®) CSA 119.2 now require that all Carbon Monoxide alarms be designed to stop service in 3 to 5 years . UL and CSA have determined that Carbon Monoxide alarms have a limited life. Propane alarms use similar sensors and UL will require the same service life in the near future.

ALL MTI Propane and Carbon Monoxide alarms which are over five (5) years old MUST be replaced. The following Safe-T-Alert Carbon Monoxide Alarm Models MUST be replaced: SA-4, SA-5, 50-541 and 50-542. Models 60-541 and 60-542 over five (5) years old MUST be replaced.The following Safe-T-Alert Propane Alarms Models MUST be replaced: SA-7 and SA-8. Models 30-441,30-442, 40-441 and 40-442 that are over five (5) years old MUST be replaced.

Important! Only install CO and Propane alarms that are UL or CSA listed for Recreational Vehicle Use.

Thank you for your question.

Sincerely,

Barbara

by Barbara 27. June 2011 14:13

Question about approved carbon monoxide alarms for use in California.

Q: "Do you sell carbon monoxide alarms on the "List of California State Fire Marshal Approved Carbon Monoxide Alarms"? The law now requires these be installed in every single family dwelling. How quickly can they be shipped. Thanks. Steve."

Answer: Yes, we do sell several approved carbon monoxide alarms. Unless you are ordering a large quantity of units, we ship within 3 business days using either the postal service or UPS.  The Fire Marshall list expires in July 2012.

Costar Models:

Kidde and Kidde Nighthawk Carbon Monoxide Alarms:

If there are other approved Kidde units you would like pricing on, please let us know. We are able to discount larger quantities of these products. Most come in case of 12 or 24 units. Remember you need to install at least one carbon monoxide alarm on each level of your home and one CO alarm in every bedroom where the door is shut at night. Do remember that if you have gas burning appliances like ranges, stoves and furnaces that you also should add gas alarms for propane or natural gas to protect against explosions and fires.

Thank you for bringing this new law to our attention.

Sincerely, Barbara

WA State Requires Automatic Gas Valve Shut Off System in New Homes

by Barbara 16. April 2011 08:06

Question about the Scentry III GFRAB Home LP/Natural Gas Detector.

Q: "How fast can you get a Scentry III system to me? Washington State now requires an automatic gas shut off system be installed before an occupancy permit can be issued for a new home who has a propane furnace in the basement. We are desperate. What I need are several components, the Scentry III GVL .75 Inch Gas Valve and the Scentry III GFRAB Home LP/Natural Gas Detector. My plumber is ready to install it. Our home rental is almost up. We are desperate. We have propane in this new home since it is in the country. Thanks. Robert."

Answer: Yours is the third sale to Washington state in the first two weeks of March. That is encouraging news to the building trade as the economy begins to improve.

The other sales were to Olympia, Seattle and to Bainbrdige Island. You live in Port Orchard. We appreciate that you've offered your contractor our contact information since we do have discounts available on packages of 6 units. We can next day air the units to you.

All customers ordered the 3/4 inch gas valve and the GRAB model. For those who are unfamiliar with these units, the Scentry models are all made in the USA, in fact in Davenport, IA. There is also a 220VAC model available for those who live outside the USA. All gas valves throughout the world are essentially sized the same so a USA made valve works fine in countries where 220V is the standard.

You should consider adding additional gas sensors if you have a propane range or propane fireplace. I know you've shared that both your water heater and furnace are in the same utility room.

In your case, you say that intermittent power failures are rare in your area plus your appliances do not have a standing pilot light. If a home owner with standing pilot light units elects to protect with a Scentry, then we do recommend the battery back-up unit.

Remember to check your carbon monoxide alarms at least monthly and change batteries annually if they are 9 volt units. There is nothing worse than an alarm beeping a low battery warning at 3 a.m.

Thank you for your question and for being our customer. We show your unit arrived on time, Next Day Air Saver, as you requested.

Sincerely,

Barbara

Thanks for your question.

Sincerely,

Barbara

120V Propane Alarms and CO Alarms Protect Park Model Trailers with Gas Appliances

by Barbara 12. April 2011 10:54

Question about the Safety Siren Propane and Natural Gas Alarm

Q: "We live in a park model modular home in a retirement community in northern Florida.  It is a one bedroom unit. Our furnace, our hot water heater and our range are all propane. A central tank supplies several homes. We've read that trailers and motor homes have 12 volt propane alarms and 12 volt carbon monoxide alarms hard-wired into the 12 volt system. Ours is 120Volt. The outlets are near the appliances and near the floor. The water heater is in a closet as is the furnace. What do we need to protect ourselves from a fire or explosion? Thanks. Tim and Diane."

Answer: In your situation, you need a minimum of two carbon monoxide alarms, one inside your bedroom and one in the living area at the other end. You need 3 propane gas alarms. Each one of your gas appliances needs a combustible gas alarm installed near to it. This means inside the closets where the furnace and the water heater reside. We understand from a park home model reseller that at least the newer models do have outlets near the appliances and near the floor.

Our suggestion is that you install two of the RV carbon monoxide units, the CoStar 9V Battery UL Home and RV Carbon Monoxide Alarm. This is because these units can handle both high humidity and high temperatures without sensors being destroyed. Operating Environment:-40 degrees F to +151 degrees F 15% to 95% RH. Since they are battery powered, you don't have to worry about plugging them into those very scarce outlets. Just change the battery out once a year.

As far as the propane alarms are concerned, we recommend that you use direct plug in units only if you have outlets close to the appliance and low to the floor. Propane is heavier than air so it sinks and pools around the bottom of an appliance. Otherwise, we recommend that you install the Safe-T-Alert Propane Natural Gas Alarm, 120V because it has a 65 inch cord that allows proper placement probably 99% of the time. This unit has micro current technology which means it uses only 3.8 watts of energy, which is about US $3.00 per year to operate. Since propane gas is heavier than air, mount this gas alarm within 4 to 20 inches of the floor. For methane or natural gas which is lighter than room air, mount the detector within 6 inches from the ceiling or on the ceiling at least 12 inches from a wall.

Thank you for your question. Remember that carbon monoxide is a by product of incomplete combustion of fossil fuels like propane, natural gas, wood, etc. Raw propane or natural gas detectors won't detect carbon monoxide nor will carbon monoxide sensors detect raw leaking gas. We do sell a combination plug in unit as well. Proper placement for carbon monoxide detector alarms is different from combustible gas alarms.  For example, gas-burning appliances may emit it a small amount of carbon monoxide when starting up. So this carbon monoxide alarm should be placed 15 feet or more from heating or cooking appliances and never hear a very humid room such as a bathroom.

Sincerely, Barbara
