That is, the strobe continues to toggle whether there is data being transferred or not. Another variation is the sharing of the same bus to transfer the strobe. In this case the strobe can only be transferred by the device that is sending the data and may require transmission of pre-ambles and post-ambles to indicate the start and end of the ...
A high-intensity white strobe is used on structures that are taller than 700 feet (210 meters). These lights provide the highest visibility both day and night. Unlike a medium strobe, a high-intensity strobe does not provide 360° coverage; this requires the use of at least 3 high strobes at each level.
Stack light in automated production for in-line quality inspection. Stack lights (also known as signal tower lights, indicator lights, andon lights, warning lights, industrial signal lights, or tower lights) are commonly used on equipment in industrial manufacturing and process control environments to provide visual and audible indicators of a machine's status to machine operators, technicians ...

The SpectrAlert series included horn strobes, strobes, remote horns, chimes, chime strobes, speakers, and speaker strobes. A main feature of these alarms was the ability to sync them using a System Sensor MDL sync module or the System Sensor sync protocol on a supported fire alarm control panel. Three years after the initial release of the ...
The standard details requirements for a range of alarm systems including central station burglar alarms, police station connected alarms, local alarms, proprietary systems, holdup alarms, and digital alarm communicator system units. It also covers power supplies essential for burglar-alarm equipment operation.
VMS systems were deployed at least as early as the 1950s on the New Jersey Turnpike. [3] The road's signs of that period, and up to around 2012, were capable of displaying a few messages in neon, all oriented around warning drivers to slow down: "REDUCE SPEED", followed by a warning of either construction, accident, congestion, ice, snow, or fog at a certain distance ahead.

Neon lamps or light-emitting diodes are commonly used for low-intensity strobe applications. Neon lamps were more common before the development of solid-state electronics, but are being replaced by LEDs in most low-intensity strobe applications. Xenon flash lamps are used for medium- and high-intensity strobe applications. Sufficiently rapid or ...
