A fire alarm system warns people when smoke, fire, carbon monoxide or other fire-related emergencies are detected. These alarms may be activated automatically from smoke detectors, and heat detectors or may also be activated via manual fire alarm activation devices such as manual call points or pull stations. Alarms can be either motorized bells or wall mountable sounders or horns. They can also be speaker strobes which sound an alarm, followed by a voice evacuation message which warns people inside the building not to use the elevators. Fire alarm sounders can be set to certain frequencies and different tones including low, medium and high, depending on the country and manufacturer of the device. Most fire alarm systems in Europe sound like a siren with alternating frequencies. Fire alarm electronic devices are known as horns in the United States and Canada, and can be either continuous or set to different codes. Fire alarm warning devices can also be set to different volume levels.

A death notification is the delivery of the news of a death to another person. It describes the moment a person receives the news of someone's death. There are many roles that contribute to the death notification process. The notifier is the person who delivers the death notice. Notifiers can be volunteers, medical personnel or law enforcement. The receiver is the designated person receiving the information about the deceased. Typically, the receiver is a family member or friend of the one who has died. Death education is provided for multiple types of jobs to deliver the news efficiently for each situation. A proper death notification allows the receiver to begin the grieving process. The history of death notification dates back to the existence of humankind, but there have always been different means of death notification. Before modern technology, death notification was done through telegram, as there were not the same means of transportation, which today allow for the more formal notification that is required. During the 1800s and early 1900s, death notification was not as complex a process as it is today. There were not the means to deliver a written notification, so notices were left at funeral homes. Today, there are more requirements to follow. One of these requirements being that the name of the deceased is not released to any outside sources until after 24 hours of the survivors being notified. One key reason being that the survivors are the first to find out in the formal manner.
