Temperature Guard Remote Monitors for Temperature, Humidity & Power Now Need No Land Lines!

by Barbara 5. November 2013 12:25

Q: "I need to know if power fails or the temperature or humidity changes in my home in Connecticut in the winter or in our motor home when we travel in the summer. We winter in Florida and take our animals with us. I live in a safe neighborhood so I am not worried about break-ins. What do you suggest?" Thanks. Calvin

Answer: I suggest you purchase the new CM712 TemperatureGuard Self-Contained Remote Monitor. Microtechnologies introduced the CM712 in late summer 2013. This replaces the VM-500-3 and VM-500-3HT units that required a land line. This is an easily set up unit suitable for computer rooms, homes, motorhomes, boats and more. You may choose to purchase two units, one for your permanent home and one for your on-the-go home. For example, if the 120VAC power in your motor home park fails or your air conditioner stops cooling, you'll know if you are shopping, etc.

The initial cost is about $600. Remember you won't have to pay for a land line. You will need a SIM card, available on a monthly basis from Microtechnologies.com, the manufacturer. Or you can get one from ATT, etc.  Alerts go via the cell network. The three sensors for temperature, power and humidity are built in. If you want you can add a dry contact door sensor. In an RV park, you probably won't need that. The "tweets" are sent right to your cell phone or computer. An internal battery back-up means alerts continue if power fails.

Text Message Alarm Notices Include:

Temperature or humidity goes out of limits

  • A door is opened  (if you have that sensor installed)
  • Water is detected. (if you have that sensor installed)
  • When the alarm condition is corrected.
  • If an alarm condition is not corrected.
  • Power outage
  • Low internal or external battery.

Dual power operation:

120vac with its included wall mount power supply.
12vdc source for use in cars, trucks, campers, boats. Requires 12 Adapter Not Included.

SIM Plan Details:

A SIM card plan is required for the CM712 to connect to the cell network. Two options are: purchase a T-Mobile SIM card through TemperatureGuard.com (Curent cost in 2013 $150 per year or $12.50 per month with an automatic renewal). Or purchase a SIM from AT&T™ or from any GSM cell service provider worldwide. No SIM card is included with the TemperatureGuard unit.

CM712 Features:

  • Quad-band EGSM 850 / 900 / 1800 / 1900 MHz
  • Works on the AT&T™and T-Mobile™ cell networks.
  • Program up to four cell phone numbers to send alarm text messages to.
  • Program an ID text so if you have more than one CM712 you'll know which one is in alarm.
  • Programmable high and low temperature limits for each sensor
  • Programmable alarm time delay for each sensor.
  • Handy reminder feature will send additional text messages if an alarm condition continues.
  • Internal rechargeable battery backup. Approximately 6 hours.
  • Ability to connect external battery for even longer life when power is out
  • Wall mount enclosure.

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

Replacing 12V Propane Gas Alarms in an RV or Trailer

by Barbara 20. June 2009 11:46

Question about replacement 12 volt propane gas alarms for a motorhome.

Q:" How do I choose the correct 12 volt propane alarm for my motor home? The brand that was in my motorhome is no longer available?" Thanks. Joe

Answer: Currently, we are selling Safe-T-Alert propane alarms, USA manufactured, that meet all RV standards. Unfortunately, we are unable to locate a manufacturer that sells a unit with the third wire, that one that closes the propane gas valve if a leak if detected.

Choose a unit by answering these questions:

Is the current propane alarm mounted flush with the wall? If so, measure the opening. The units we sell are:

  • 30-442 (Flush Mount)Case Dimensions:6.375"W x 2.875"H x 1"D
  • 40-442RV Flush Mount Gas Alarm: Case Dimensions Recessed portion = 3"H x 4"W. Depth = 1 1/8". Flush mount portion = 4"H x 4 7/8"W. Screw Holes = centered, 4 1/2" apart.

Is the current propane alarm surfaced mounted, ie. not flush with the wall?

  • 30-441 (Slim Line Surface Mount): Case Dimensions: 6"W x 1.875"H x 1.5"D
  • 40-441RV Case Dimensions: Bottom (where mounted) = 3"H x 5 3/8"W. Top = 3"H x 5"W. Depth = 1 3/8". Screw holes = centered, approx. 5" apart.

Do you want a brown unit?

  • 40-442A-BR is chocolate brown and a flush mount. The 40-441A-BR is the corresponding surface mount unit.
  • The 30-441A=BR is the chocolate brown surface mount propane alarm and the 30-442A-BR is the chocolate brown flush mount model.

What is the maximum amp draw you want?

  • Both the 40-441 and 40-442 draw 46 milliamp (0.046 amp.)
  • The 30-441 and 30-442 draw 76 mA. This 30-442 can replace the CCI-7770 Propane Alarm that is discontinued.

The warranties are longer on the 40 series units. If you are interested in the product manuals, we have them listed below the pictures of each product.

I hope this helps answer your question. We do recommend that you test your propane alarms and your RV carbon monoxide alarms at least once per month.

Sincerely, Barbara
