In the few month, I have assigned to design an integrated fire alarm system and emergency announcement system for a resort hotel. Almost project is going well but I have a problem in design concept of NAC and Emergency paging because my boss said it shall be separated that mean I have to do 1 NAC by using strobe light with horn or bell as a equipment and another 1 NAC by using speaker (He said it not necessary to be listed equipment) and I have to do a proper programming to control these 2 circuit..
But my question is can I only do 1 NAC by using FRC and listed speaker with strobe light then I program the system to do an announcement pattern what he want. Are there any code require it to be separated circuit and If my boss concern about amplifier, can I do a back up amplifier to prevent this cause.
Note: my FACP is notifier NFS2-3030.
