Voice evacuation systems (also called Voice Alarm Systems) have become popular in most countries. Voice evacuation alarms typically are not as loud as horns or bells (although generally standards require the same minimum sound pressure levels), and usually sound an alarm tone (typically a slow whoop, code-3, or chime tone, although this depends ...
The design of the flutter valve features a rubber sleeve in a plastic case, where the rubber sleeve is arranged so that when air flows through the valve the sleeve opens and allows the outwards airflow from the body of the patient; however, when the airflow is reversed, the rubber sleeve closes and halts backwards airflow into the body of the ...
The engineering design process, also known as the engineering method, is a common series of steps that engineers use in creating functional products and processes. The process is highly iterative – parts of the process often need to be repeated many times before another can be entered – though the part(s) that get iterated and the number of such cycles in any given project may vary.
An alarm device is a mechanism that gives an audible, visual, combination, or other kind of alarm signal to alert someone to a problem or condition that requires urgent attention. Etymology [ edit ]
More complex evacuation planning is now being considered, such as using elementary schools as rally points for evacuation.

Their locations and inherent design to accommodate bus transportation makes it an ideal evacuation point.
Manual fire alarm activation is the process of triggering a fire alarm through a call point, pull station, or other device. This usually causes the alarm to sound the evacuation signal for the relevant building or zone.
