Telephone Emergency Notification System (TENS) is a high speed communications system that delivers emergency information or warnings to designated geographic areas.

TENS is a combination of telephone, computer, and Geographic Information System (GIS) technologies.

TENS is a very important communications note to put out there and we need it to be presented in the most complete manner possible.

TENS is used to communicate such information as:

  • imminent flooding
  • sheltering instructions
  • evacuation routes
  • missing person alerts
  • and more

By simply selecting an area that needs to receive emergency information, the message is prerecorded and then automatically calls the homes in the selected area - up to 22,000 per hour. It's another great way to communicate important information during an event.

TENS is managed by the Marin County Office of Emergency Services and as long as you have a landline you are able to receive these important calls during the time of an emergency. If you have a cordless phone or your service provider is also your cable provider you should double check that they have registered you with the emergency notification database.

TENS Question & Answer

  1. QUESTION: What information do you have on the citizens who are being called and where does the information come from. How is this information accessed or collected?
    ANSWER: Â We collect all phone numbers from Verizon and AT&T and upload them to our servers quarterly. The only people that can access these numbers and activate our TENS system is our County OES staff. These numbers are not given out to anyone else for any reason.
  2. QUESTION: If I am called, what information appears on my caller ID?
    ANSWER: The numbers that will show up on your caller ID varies depending on the method we use. They could be any of the following numbers: 415-507-1513, 480-629-0003, or 615-514-0815. If you have a standard voicemail/answering machine, the system will leave a message. If you have a voicemail/answering machine that says press 1 for Joe, 2 for Mary, etc., the system will not leave a message.
  3. QUESTION: Does TENS work with the relatively new internet/broadband/VoIP phones, e.g. Vonage or Comcast digital or AT&T U-verse digital?
    ANSWER: AT&T and Verizon cover the VOIP numbers for AT&T U-verse and Comcast, so those numbers are uploaded into the TENS database. As for Vonage, they do not have this option. Vonage subscribers must call Vonage to ask them to provide their numbers to AT&T & Verizon so those numbers will be covered when a call out is made. It's up to the subscribers to get Vonage to do this.
  4. QUESTION: What is the Emergency Notification Database and can any number be listed?
    ANSWER: It is up to the subscriber to contact their phone carrier and make sure that their number is added to the list of phone numbers provided to Marin County OES for emergency call outs. AT&T & Verizon do this automatically.

911 / e911

There are some differences with the 911/e911 service for these online phones.

e911 service is the number that is provided to Communication Dispatch Center. If you call 911 from your home phone, your address shows up on the Dispatch screen for a faster way to get help dispatch first responders to your home.

We've all seen the food pyramid where the food at the bottom of the pyramid is supposed to be eaten regularly, and the food at the top sparingly.Now comes the Pyramid of Conservation.

This pyramid was created for Minnesota Power to help residential customers determine where to start with energy efficiency projects.

The Conservation Pyramid has 10 levels, from cheap at the bottom to expensive at the top.

Pyramid of Conservation

While some may argue with the details in this pyramid, the pyramid's basic hierarchy is sound.

Many people who want to green their home start at the top instead of the bottom. The whole point of this pyramid is that you should start with the easy and cheap stuff - the low hanging fruit - at the bottom of the pyramid.

Before you spend lots of money on new appliances and renewable technologies that take many years to amortize you should make all the inexpensive efficiency improvements and reduce your overall energy consumption that way.

The Pyramid of Conservation helps you prioritize energy efficiency steps. First you establish a foundation in energy efficiency and then you can work your way up the pyramid. Click any topic on the pyramid to learn more!
