A message is a discrete unit of communication intended by the source for consumption by some recipient or group of recipients. A message may be delivered by various means, including courier, telegraphy, or an electronic bus. A message can be the content of a broadcast. An interactive exchange of messages forms a conversation. The consumption of the message relies on how the recipient interprets the message, there are times where the recipient contradicts the intention of the message which results in a boomerang effect. Message fatigue is another outcome recipients can obtain if a message is conveyed too much by the source.
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.
A tornado warning is a public warning that is issued by weather forecasting agencies to an area in the direct path of a tornado, or a thunderstorm capable of producing one, and advises individuals in that area to take cover. Modern weather surveillance technology such as Doppler weather radar can detect rotation in a thunderstorm, allowing for early warning before a tornado develops. They are also commonly issued based on reported visual sighting of a tornado, funnel cloud, or wall cloud, typically from weather spotters or the public, but also law enforcement or local emergency management. When radar is unavailable or insufficient, such ground truth is crucial. In particular, a tornado can develop in a gap of radar coverage, of which there are several known in the United States.
A long-range acoustic device (LRAD), acoustic hailing device (AHD) or sound cannon is a specialized loudspeaker that produces sound at high power for communicating at a distance. It has been used as a method of crowd control, which has caused permanent hearing damage, having an extremely high decibel capacity. Other uses have included for negotiations in siege situations to deal with piracy at sea; for mass notification during natural disasters or other emergencies; and by defense forces, including several navies.
A public-safety answering point (PSAP), sometimes called a public-safety access point, is a type of call center where the public's telephone calls for first responders are received and handled. It takes calls from any landline, mobile phone line, or VoIP line. It can also happen that when 112 is dialed in then a logic is implemented by mobile or network operators to route the call to the nearest police station. Such call centers exist in most countries to answer calls to an emergency telephone number. Trained telephone operators are also usually responsible for dispatching these emergency services. Most PSAPs are now capable of caller location for landline calls, and many can handle mobile phone locations as well, where the mobile phone company has a handset to location system. Some can also use voice broadcasting where outgoing voice mail can be sent to many phone numbers at once, in order to alert people to a local emergency such as a chemical spill.
An emergency population warning is a method where by local, regional, or national authorities can contact members of the public to warn them of an impending emergency. These warnings may be necessary for a number of reasons, including:
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.
Association of Public-Safety Communications Officials (APCO) International was founded in 1935.
The National Warning System (NAWAS) is an automated telephone system used to convey warnings to United States-based federal, state and local governments, as well as the military and civilian population. The original mission of NAWAS was to warn of an imminent enemy attack or an actual accidental missile launch upon the United States. NAWAS still supports this mission but the emphasis is on natural and technological disasters. Organizations are able to disseminate and coordinate emergency alerts and warning messages through NAWAS and other public systems by means of the Integrated Public Alert and Warning System.
Alert messaging is machine-to-person communication that is important or time-sensitive. An alert may be a calendar reminder or a notification of a new message.
Next Generation 9-1-1 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 9-1-1 from a phone, it intends to enable the public to transmit text, images, video and data to the 9-1-1 center. The initiative also envisions additional types of emergency communications and data transfer. This NG9-1-1 infrastructure is intended to replace the current services over time. The National Emergency Number Association (NENA) first identified the need for NG9-1-1 in 2000, and started development actions in 2003, and is nearing full definition and standards for NG9-1-1. 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 NG9-1-1. On January 24, 2013, the CRTC announced the first step toward a Canadian implementation of NG9-1-1 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 NG9-1-1, 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.
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.

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.
MessageNet systems is a privately held company which sells a primarily software-based product called "Connections" for facilitating an organization's emergency and routine communications.
Alberta Emergency Alert (AEA) is a public warning system in Alberta that warns the public on impending or occurring emergencies affecting an area. The system was implemented in October 2011, replacing the former Alberta Emergency Public Warning System. Alerts are disseminated through various media outlets including television and radio, internet, social media mobile apps, and cell broadcast.
An emergency notification app is a software application designed to broadcast emergency notifications to one or multiple groups of contacts via various delivery methods. It is built to run on mobile devices such as smartphones and tablet computers. An emergency notification app may be part of a wider emergency notification system or it may be provided as an alternative to such a system.
ISO 22322:2022 is an international standard developed by the ISO/TC 292 Security and Resilience committee. It was published by the International Organization for Standardization (ISO) in 2015.
There are various Wireless Emergency Alerts in Germany which inform citizens about important incidents, disasters and dangerous situations, as well as severe weather. Since February 2023, the alerts of the four main systems have been shared and disseminated in parallel.
