Reverse 911 is a public safety communications technology used by public safety organizations in Canada and the United States to communicate with groups of people in a defined geographic area. The system uses a database of telephone numbers and associated addresses, which, when tied into geographic information systems (GIS), can be used to deliver recorded emergency notifications to a selected set of telephone service subscribers. [1]
Reverse 911 was developed by Sigma Micro Corporation, later known as Sigma Communications, in 1993. [2] After a number of corporate acquisitions, Motorola Solutions ultimately gained ownership of the technology and rights developed by Sigma, and Motorola has folded Reverse 911 into their Vesta suite of public safety systems. [3]
The system is used to notify residents in emergency situations, for example:
Enhanced 911 is a system used in North America to automatically provide the caller's location to 911 dispatchers. 911 is the universal emergency telephone number in the region. In the European Union, a similar system exists known as E112 and known as eCall when called by a vehicle.
Motorola Solutions, Inc. is an American video equipment, telecommunications equipment, software, systems and services provider that succeeded Motorola, Inc., following the spinoff of the mobile phone division into Motorola Mobility in 2011. The company is headquartered in Chicago, Illinois.
A fire alarm system is a building system designed to detect, alert occupants, and alert emergency forces of the presence of fire, smoke, carbon monoxide, or other fire-related emergencies. Fire alarm systems are required in most commercial buildings. They may include smoke detectors, heat detectors, and manual fire alarm activation devices. All components of a fire alarm system are connected to a fire alarm control panel. Fire alarm control panels are usually found in an electrical or panel room. Fire alarm systems generally use visual and audio signalization to warn the occupants of the building. Some fire alarm systems may also disable elevators, which are unsafe to use during a fire under most circumstances.
A medical alarm is an alarm system designed to signal the presence of a hazard requiring urgent attention and to summon emergency medical personnel. Other terms for a medical alarm are Personal Emergency Response System (PERS) or medical alert. It is especially important to recognize the need to respond to situations where the person is unable to summon help.
The Minot train derailment occurred just west of Minot, North Dakota, United States, on January 18, 2002, when a Canadian Pacific Railway freight train derailed, spreading ammonia gas across the city, delaying rescue operations. The cause was found to be small fatigue cracks in the rails and joint bars, not detectable by the inspection routines then enforced by Canadian Pacific.

Notify NYC is the City of New York's official source for information about emergency events and important City services. It is a free service launched by the NYC Emergency Management and New York City Department of Information Technology and Telecommunications (DoITT) in 2007, allowing users to receive alerts through various communications devices, such as cell phones, landlines, email, Twitter, and RSS. Users can specify which alerts they would like to receive, and determine their specific location of interest with zip codes. Registration is free and simple. Notify NYC services residents and visitors to all five boroughs of the City of New York: Manhattan, Brooklyn, Queens, Staten Island, and the Bronx.
Shelter-in-place is the act of seeking safety within the building one already occupies, rather than evacuating the area or seeking a community emergency shelter. The American Red Cross says the warning is issued when "chemical, biological, or radiological contaminants may be released accidentally or intentionally into the environment" and residents should "select a small, interior room, with no or few windows, taking refuge there."
The HEARO Local Alert Receiver was an emergency management tool to relay and display informational text messages in English, Spanish, French and German using RDS technology. It notified local residents in the event of an emergency within a matter of seconds. HEARO carried NOAA weather warnings and other public safety text alerts, using FM radio infrastructure with a 60-hour battery life, HEARO was able to work when electricity, telephone and Internet were unavailable. viaRadio Corporation of Melbourne, Florida manufactured and distributed HEARO receivers.
Next Generation 911 refers to an initiative aimed at updating the 911 service infrastructure in the United States and Canada to improve public emergency communications services in a growing wireless mobile society. In addition to calling 911 from a phone, it intends to enable the public to transmit text, images, video and data to the 911 center. The initiative also envisions additional types of emergency communications and data transfer. This NG911 infrastructure is intended to replace the current services over time. The National Emergency Number Association (NENA) first identified the need for NG911 in 2000, and started development actions in 2003, and is nearing full definition and standards for NG911. Since 2006, the US Department of Transportation (DOT) in the United States and the Canadian Radio-television and Telecommunications Commission (CRTC) in Canada have been leading their respective initiatives, which include research and development projects aimed at advancing NG911. On January 24, 2013, the CRTC announced the first step toward a Canadian implementation of NG911 and, in March 2016, began a consultation with the public to discuss what services should be offered, who will play a role in offering these services and how these services should be paid for. Several US states have implemented versions of NG911, as of October 2013.
The Mount Rainier Volcano Lahar Warning System consists of two separate components, operating in tandem: Acoustic Flow Monitors (AFM) and the All Hazard Alert Broadcast (AHAB) sirens. The AFM system was developed by the United States Geological Survey (USGS) in 1998 and is now maintained by Pierce County Emergency Management. The purpose of the warning system is to assist in the evacuation of residents in the river valleys around Mount Rainier, a volcano in Washington, in the event of a lahar. Pierce County works in partnership with the USGS, the Pacific Northwest Seismic Network (PNSN), Washington Military Department's Emergency Management Division, and South Sound 9-1-1 to monitor and operate the system.

An emergency communication system (ECS) is any system that is organized for the primary purpose of supporting one-way and two-way communication of emergency information between both individuals and groups of individuals. These systems are commonly designed to convey information over multiple types of devices, from signal lights to text messaging to live, streaming video, forming a unified communication system intended to optimize communications during emergencies. Contrary to emergency notification systems, which generally deliver emergency information in one direction, emergency communication systems are typically capable of both initiating and receiving information between multiple parties. These systems are often made up of both input devices, sensors, and output/communication devices. Therefore, the origination of information can occur from a variety of sources and locations, from which the system will disseminate that information to one or more target audiences.
An emergency notification system is a method of facilitating the one-way dissemination or broadcast of messages to one or many groups of people, alerting them to a pending or existing emergency. The Emergency Notification System (ENS) was created by Dialogic Communication Corporation (DCC) in the early 1980s. DCC, including its patent portfolio, was purchased by Motorola Solutions as part of their 2018 acquisition of Airbus DS Communications.

The National Public Alerting System, branded as Alert Ready, is the national warning system in Canada, broadcast to Canadian television, radio, and wireless devices.
On February 1, 2005, the Emergency Alert System was activated in portions of Connecticut calling for the immediate evacuation of the entire state. The activation was in error. Later studies showed that residents did not evacuate, and that the most common response was to 'change the channel' or seek other confirmation.
