Access for People with Special Needs

All work stations at the communications center are equipped with Telecommunication Devices for the Deaf (TDD). These devices allow typed (text) communication with the hearing and/or speech impaired.

 If a caller doesn’t speak English, our center has Spanish-speaking operators on-duty most of the time that can take your call. However, if there is no one available (or the caller speaks a language other than Spanish), our center has access to Language Line Services that provide 24 hrs/day over-the-phone interpretation of over 175 different languages. The process of getting an interpreter on the phone with the caller usually takes less than one minute.


Things to Remember

  • 9-1-1 is a free call from any phone including pay phones and cell phones.
  • If you dial 911 by mistake, Do Not Hang Up! Remain on the line and tell the operator it was a mistake. This will avoid a callback or response from Tucson Police.
  • Do not allow your children to play with home phones or cell phones as many of them dial 911 accidentally.
  • Make sure your house and/or mailbox are numbered with the correct address. Reflective numbers work best in the dark and if painted on the curb.
  • If it is dark outside, turn some outside lights on.
  • Put away any pets living inside your home that might get in the way of the responding units.
