If you are broadcasting from a single point, you must ensure that every connection from building to building is connected via fire retardant cabling. Â Many multiple building sites use a basic paging system to alert security personnel or the estates manager to a fire alarm across the site. Â The cabling between buildings may be network cable or even telephone cable. Â As this alert is for "information only" it has no overarching legal requirements on it and few standards. Â After all, if the system fails, it doesn't matter as the building will still be evacuated.
However, once you attach a DeafWatch - Deaf Fire Alarm or equivalent system to the end of that process, your paging system then counts as part of the fire alarm. The DeafWatch signal is the only fire alarm for the deaf person concerned. Therefore it is imperative that all connections from the activation point, between buildings and through subsidiary fire alarm panels, back to the main panel and through to the DeafWatch transmitter are cabled securely in fire retardant or equivalent secure cabling.
