Denver 911 operators are trained to ask questions that will help you get the assistance you need as quickly as possible. It is important to stay on the line with your 911 operator until you receive instructions to hang up. If you are in danger, you may be instructed to leave the building, secure yourself in a room, or take other protective actions.
Officers always try to respond as quickly as possible; however, there are a number or factors that determine how long you may wait for an officer to respond. For instance, the number of incidents and priority of calls could delay the officer from responding to your incident immediately. The type, and priority of calls determine the response time as will the number of available officers in your neighborhood.
While it is reasonable to want to know how long it will take for an officer to respond, there are several logistical and operational barriers that make it difficult for call-takers to provide citizens with an estimated time of arrival (ETA).
Due to the dynamic of constantly changing call volume, officer availability cannot be precisely estimated. Some calls may be resolved in just a few moments, while others require more thorough investigation and could take hours to complete.
When you call for assistance, whether you are reporting an emergency or a non-emergency situation, your incident is entered into our Computer Aided Dispatch System (CAD) for tracking purposes. We verify your address, obtain your contact numbers, create a short summary of what is happening, determine the nature of incident, and assign a priority ranking to the call. These priority rankings are established by the Denver Police Department.
Call volume in the 911 Communications Center fluctuates through the day. At any time, we can receive numerous high--priority calls, or perhaps a single call requiring multiple-officer response. Emergency calls always take priority and are dispatched first. Priority rankings are established by the Denver Police Department.
Officers are sometimes diverted from lower-priority calls to respond to higher-priority emergencies. This process ensures safety for our citizens and Denver’s first responders, but may increase the response time for lower-priority calls.
Denver Police Officers are also diverted to assist Denver Health Paramedics handling medical emergencies and the Denver Fire Department at large scale fire emergencies.
If you mistakenly reach 911, please do not hang up before the 911 Operator answers the phone. The information from your phone still enters our system. If you aren’t on the phone when the Operator answers, she or he will call you back. The time spent calling people back who have inadvertently dialed 911 takes time away from people who need emergency help.
VoIP subscribers enjoy certain advantages like free long distance, or cheaper options for local and cellular phone services. However, VoIP calls present problems for 911 answering systems and can often be routed to the wrong 911 center or be accidentally dropped.
In addition, because VoIP is transmitted over the Internet, the caller’s associated number often cannot be recognized by emergency 911 systems. The 911 system provides Automatic Number Information (ANI) and Automatic Location Information (ALI) which is rendered virtually useless for VoIP users.
VoIP subscribers should take precautionary steps to ensure their safety when emergency services are needed.
Wireless cell phones can be an important public safety tool, but they also create a unique challenge for public safety and emergency response personnel in locating the caller. The precise location of a caller who dials 911 from any cell phone cannot be determined. Therefore, it is essential that you stay on the line and clearly give your location to the 911 Operator.
A wireless phone is actually a radio with a transmitter and a receiver that uses radio frequencies or channels (instead of telephone wire) to connect callers. Because wireless phones are by their very nature mobile, they are not associated with one fixed location or address.
The Federal Communications Commission (FCC) has taken a number of steps to increase public safety by coordinating development of a nationwide, seamless communications system for emergency services that includes the provision of location information for wireless 911 calls. This effort has been implemented in three phases: Phase 0, Phase I, and Phase II.
Wireless Phase II, in effect now, requires carriers to provide far more precise location information - within 50 to 300 meters (approximately 170 to 1000 feet). The cell phone vendors have different methods in which the cellular phone handset can provide the latitude and longitude for the caller, either through triangulation, GPS or a hybrid of the two. Denver is compliant with Phase II; however, your cell phone must also be compliant to obtain more detailed location data.
