Emergency 9-1-1 System


9-1-1 is for emergency use only!!!

All other calls for should be made to our non-emergency number: 973-627-4900

Generally, whenever you dial 9-1-1 from a telephone within Denville Township, your call will be answered by a dispatcher at our police headquarters. Our dispatcher will need to know who is calling, where you are calling from, the phone number of the phone you are calling from, and the nature of the emergency. It is important for you to try to remain calm and speak in a clear voice.

If your 9-1-1 call involves a medical emergency, the dispatcher may also transfer your call to an Emergency Medical Dispatcher to provide you with pre-arrival instructions if appropriate.

9-1-1 and the Law


Under NJ Law, it is illegal to make false/prank phone calls to 9-1-1. NJ Statute 2C:33-3.e states,

"A person is guilty of a disorderly persons offense if the person knowingly places a call to a 9-1-1 emergency telephone system without purpose of reporting the need for 9-1-1 service."

If convicted for a violation of this statute, you could face up to 6 months imprisonment and a $500.00 fine.


9-1-1 Checks


Under our New Resident Visit Program, an Officer will visit all new residents to test their connection to our 9-1-1 system. If any errors are discovered, the Officer will make the proper notifications to ensure that they are corrected.

If you are not a new resident and would like to check your connection, please call our police dispatcher at 973-627-4900 ext 9. Advise the dispatcher that you wish to check your 9-1-1 connection. They will ask you to hang up and then dial 9-1-1. After answering your call, they will confirm with you that the information displayed on the screen is accurate.

9-1-1 and Cell Phones


Depending on your service provider, 9-1-1 calls placed from a cell phone will not provide us with your exact location. Your location may be generated based upon the cell tower your call is being transmitted from or through GPS. Both of these methods are not very accurate in determining your exact position. Therefore, it is imperative that you try to remain calm and answer any questions the dispatcher may have, especially regarding the location of the emergency

The same holds true for phone service that is provided by voip (voice over internet protocol). Even worse, some of these voip companies may not even offer 9-1-1 service

Due to this problem, we strongly encourage all residents to have at least one hard wired telephone.
