Question:
Where can I find the regulations for alarm system installations? Fire alarms, etc. Mainly for commercial installs but would also like for residential also. Is there a code book for these?

Answer: -NFPA 72 and NEC are the two major codes with which you will be concerned. The former is the fire code. The latter is the National Electrical Code. On commercial applications and to a lesser extent residential jobs you will also have to comply with ADA, which is a federal law. Your local Fire Marshal or Building Inspector may be of some help.

-http://www.nfpa.org is for the fire alarm code. There is none for burglar alarms since they are not regulated in that way, although some towns require you to get a permit just the same. It's to make money mostly.
