Learning How the System Works

Fire Alarm Engineers, Installers, Technicans, and Inspectors get Answers from Douglas Krantz's Technician's Corner

A fire pull box is part of a fire alarm system
The rules and codes show what the fire alarm system does. However, those working on the system require a knowledge of how it functions in order to design the system, install it, test it, and service it.

Basic Electrical Skills

A basic understanding of electricity is required. Knowing about DC and AC electricity and Ohm's Law shows how a fire alarm system sends signals back and forth, and how it powers and controls devices.

Life Safety Upgrades

The fire alarm system, though, in addition has the goals of Supervision (self-testing and letting the building owners immediately know that something's wrong with the system), Redundancy (if one method fails, another method is standing-by to take over), and Survivability (even during a fire or other disaster, the system still works).
Th1s website and the books that are offered are designed with the electronics of signal system in mind, combined with the goal of life safety.
