The Codes show what is required for a Fire Detection and Alarm Systems; but a fire alarm technician needs to know how the systems work in the first place.
Understand how a two-wire addressable signaling line circuit works. Plain language is used to explain:
- Why the addressable devices have to be addressed
- How the panel provides power to the addressable portions of the modules and input devices
- Why the voltage of the SLC seems so unsteady when measuring with a voltmeter
- How the panel and the addressable modules & devices communicate with each other
Use what you’ve learned as you design, install, and service addressable fire alarm circuits and devices.
