Replace Safe-T-Alert RV30-441 Propane Alarm With a Safe-T-Alert 35-741,CO Alarm/Gas Alarm Combo

by Barbara 24. October 2013 06:05

Question about replacements for CCI Controls Propane Alarm 7770.244.

Question: "What 12 Volt RV gas alarm can replace my CCI Controls 7770.244 that is beeping? I also need a new carbon monoxide alarm." Thanks. Steve.

Answer: Safe-T-Alert has two units, the Safe-T-Alert 30-441 and the Safe-T-Alert 35-741. Both are surface mount units.  If you want to add more carbon monoxide detection, I suggest the new combination units, the 35-741 which comes in a black surface mount RV alarm and a white unit. The 30-441, gas only monitor with alarm, comes in brown and white. Both have approximately the same dimensions as the old CCI units.

If your carbon monoxide alarm is hard-wired, please look at these two units, the Safe-T-Alert 65-542 and the Safe-T-Alert 65-541 . The first is flush mounted, i.e. the rear of the unit goes into your RV wall. The second is flush mounted. These are available in white, brown and black.

If your carbon monoxide alarm is battery powered, consider replacing it with the Costar 9RV which meets all the RVIA specs for humidity and temperature ranges. For more protection, install the Costar 12RV-DB which hooks to both your coach 12 volt system and to your RV 12 volt engine battery. This unit draws from the unit with the most power and also has a 9 volt battery back-up.

And make sure your smoke alarm was replaced within the past 5 years as well. Nothing more annoying than being woken in the middle of the night by a false alarm! The Safe-T-Alert 775 is a 9 volt battery powered unit that is UL listed and approved for RV use.

Thanks for your question.

Sincerely,

Barbara

Repel Mice, Rats, Cats and Squirrels from Car Engine Compartments with Ultrasonic Repeller

by Barbara 19. June 2013 08:55

Question about how to keep animals from chewing up wiring in my parked car.

Q: " How can I keep mice and squirrels from getting under my car and nesting in my car's engine compartment. I live in the mountains of Colorado and do not have a garage. If I leave a vehicle parked for several days, I risk having small animals from nesting or crawling into the underside of my car. I've had to have wiring repaired several times. Thanks. Tom."

Answer: You are not the first person to ask for such a product. Years ago there was a 12 volt product made in China or India that attached to one' car battery and produced ultrasounds to get rid of pest animals under a vehicle. That was never imported.

Now P3 International has an inexpensive under the hood product that runs off C cells. This animal repeller, the P7825 Under Hood Animal Repeller, keeps your engine compartment safer from squirrels, rabbits, rats, martens/sables etc. At higher elevations or in colder weather, rats, cats and other animals seek shelter and warmth in engine compartments. There they chew on cables, wiring harnesses and other expensive parts.

Under Hood Pest Repeller Features

  • Easily mounted: 4 Eight Inch Vinyl Cable Ties Included Plus Two Screws with Plastic Screw Holders
  • Battery operated
  • Water Resistant
  • LED Indicator
  • On/Off Button

  • Battery Life:6-8 months (longer with alkaline)
  • Dimensions (L x W x H):5 1/8" x 2 1/2" x 1 5/8"
  • Weight:4 oz.

Operation and Instructions:

  1. Open the battery door by unscrewing the metal screw.
  2. Insert Two C size batteries (not included, alkaline or better recommended).
  3. Close door. Unit is ready to use.
  4. Cautions: Avoid high temperature areas such as exhaust manifold. Do not place where unit will interfere with moving parts.
  5. Switch on by depressing and holding on/off button for 2 seconds. LED will light and unit switches on. Switch off if desire by holding button for 2 seconds.
  6. In operation, the unit sounds a 12 kHz frequency tone.
  7. Status LED lights up when unit is activated.

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

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
