are you a third party approved contractor within the fire alarm industry ?
if not, in th UK, you have to be third party approved to be able to obtain URN (Unique Reference Numbers) for fire alarm systems that transmit an alarm status to a Alarm Receiving Centre.
also under EN54 (or even BS5839 pts 1 4 1988 amended 2000) you cannot add a device to a fire systems monitored sounder circuit,
you must connect any communications equipment IE a Digital Communicator or a Redcare (fire STU Subscriber Termination Unit) via the connections provided by the control panel manufacturer.
its a bit of a mine field out there at the moment in regard to monitoring fire systems, you would be better off talking to the SSAIB or go one line to there website, that will give you a good load of information.
if you need any further info, drop me a line.
