Red Flashing Beacon

The white or red flash strobe beacon integrates 
into fire detection and alarm systems. 

It is used to warn the people in a building of a fire risk. 
It emits a light signal that alerts the occupants of the protected premises and lets them take appropriate safety measures. 
Other colors are used for other applications 
such as event signaling. It is particularly well suited to noisy premises or those occupied by deaf or hard-of-hearing people.
