An Emergency Notification Service, or "ENS," uses the 9-1-1 database of all wireline telephone numbers within a County to look up numbers of phones in an area threatened by a public hazard, and place warning calls to those telephone numbers. When a wildfire, tornado, flash flood, chemical spill or other hazard threatens an area, Public Safety Officials can identify the area affected and the ENS system will identify all wireline telephone numbers at addresses in the area. The ENS system will then place telephone calls to each of those telephone numbers, and play a recorded message alerting residents to the hazard and instructing them as to actions they should take.

Newer, Enhanced Emergency Notification Services allow residents to add their cell phone numbers, Internet phones, pagers, fax machines, text message addresses, e-mail addresses and other telephone numbers and messaging addresses to the ENS Database. When the ENS system is activated, the service will send recorded or text messages to each of these numbers and addresses in addition to your home phone (if you have one). The Services let you know when a public emergency threatens your home or work even if you are not at your home or work. Even if you are at home or work, having multiple paths to notify you of the emergency may allow you to receive the message sooner... particularly if the local telephone network is overloaded and calls are blocked as often occurs in emergencies.

When you receive a call from an ENS or Enhanced ENS system, please do not call 9-1-1 to confirm the message. During a public emergency, the 9-1-1 Call Center(s) and Emergency Operations Center(s) will be busy handling 9-1-1 calls, dispatching First Responders and coordinating First Responder activities. Calls to 9-1-1 to confirm an ENS message may block calls from people needing help, and distract public safety officials from responding to emergencies. Making phone calls through your local exchange will also block and delay ENS calls to your neighbors to warn them of the hazard. In addition, the time you spend trying to call 9-1-1 to confirm the warning and instructions could waste valuable minutes, particularly in the case of an evacuation notice for a wildfire or flash flood or chemical spill, or a take-cover notice in the event of a tornado. If you have questions or concerns regarding ENS services, please contact your local Sheriff or Police Department.
