2013 NFPA 72 26.2.4 Alarm Signal Content.  Where required by the enforcing agency, governing laws, codes or standards, alarm signals transmitted to a supervising station shall be by addressable device or zone identification.  


My question has manifested due to a campus style system at an apartment complex in Naples Fl. which is using the clubhouse panel as the fire alarm panel with cell DACT to transmit the fire alarm signals to the remote monitoring station.  Each building has been addressed by the county with different addresses.  The signal is being received at the remote monitoring station with the Clubhouse address and being dispatched with that address and supplemental information containing the building address and type of alarm signal (waterflow, pull, smoke, etc.) which is in alarm.  The issue has been discovered due to the technology in DACR transmission.  The signal is being sent automatically to 911 center via computer.  The reception of these signals are being captured at the 911 center (PSAP) with the utilization of a computer.  No voice communication between the DACR and the 911 center (PSAP)  is occurring.  The initial signal of the alarm (which is reporting to the remote monitoring station as the Clubhouse address) may come in between 10 and 180  seconds ahead of the supplemental information containing the building address in alarm and the type of alarm.  In some cases, this is allowing the signal received by the 911 dispatch center (PSAP) to be pushed out to the responding fire apparatus with incomplete information.  This can be corrected if the 911 dispatch center (PSAP) has a CAD, Computer Aided Dispatch, system that automatically pushes out updates, some do not.  

Does 2013 NFPA 72 26.2.4 support the AHJ in requiring that each signal received by the Clubhouse fire alarm and DACT, from these outlying buildings with different addresses, receive the address at the PSAP?
