As fire alarm system technology continues to advance, facilities that rely on older systems may miss opportunities to improve important aspects of fire/life safety performance or to solve problems that older systems cannot address.
One benefit of new fire alarm system technology is improved communication. Combine the powerful information provided by field detection devices with the ability to capitalize on high-speed data transmission provided by fiber optic transmission media, wide-area and local-area networks, and you have fire alarm systems capable of sending very detailed information via Internet-based digital alarm communicator transmitters or direct networks to emergency responders or off-site monitoring locations with device specific detail.
Because the fire alarm industry knew little of professional sound and communication principles, early generation voice communications systems provided unintelligible notification messages that were solely used for fire alarm functions and fire department operations. The voice communications component of fire alarm systems has evolved to the point that specifically routed messaging can deliver clear emergency and non-emergency messages, including music. This change required the fire alarm industry to realize that redundant voice communications systems, like PA systems and music systems, could be replaced by fire alarm voice communications systems. Codes in place require the industry to supervise speaker circuits for integrity in the active state. In other words, while music is playing, the fire alarm system must be capable of identifying that a circuit has been damaged or broken. Today this capability is now commonplace for the major fire alarm system manufacturers.
Over the last 10 years, fire alarm systems have begun to evolve into multi-faceted mass communication platforms, largely as a result of terrorist events and government or military needs. These mass communication capabilities include fully intelligible voice messaging systems that can integrate textual signage. Multi-faceted mass communication plans can now draw on the fire alarm system to provide message outputs via text messaging, paging and email. Additionally, fire alarm systems can be seamlessly integrated with wide area mass notification systems that use high-power outdoor speaker arrays that can reach large geographical areas with highly intelligible messages.
