Fire and Industrial Signalling

In the great majority of automatic fire alarm sounders or fire alarm systems, the end result of the detection of a fire is the initiation of audible and visual warning devices that alert the occupants to the danger so that they can evacuate the premises.

Given the complexity and variation of different types of buildings and structures in which fire alarm sounders are installed, and the further variations to be found in the homogeneity or otherwise of the occupants, it is clear that, for maximum effectiveness, many different types of fire alarm sounders will be required.
