Trumpy,
requirements to install fire alarms vary from state to state, and even from county to county. Generally, a license is required to work on these systems.

In my home state of Rhode Island, a Master Electricians License permits you to work on any electrical system, inluding burglar and fire alarms.

There is also a Fire Alarm License which allows you to work on fire alarms. The only line voltage work you can do is install the 120 volt feed to the FA panel.

I know a bit about this since I used to work on fire alarms. If you have any questions, just ask. [Linked Image]
