Fire Alarm Systems

When the alarm sounds, break glass

Electronic Fire Alarm Systems

A fire alarm system detects fire and tells people about the fire. However, between the detect and the tell, there's an unseen, building wide electronic fire alarm system.

Codes versus Making the Fire Alarm System Work

At least once a fire alarm system has been installed and finished, the codes and rules describe how it should work. However, if the electronics of a fire alarm system don't work, the codes and rules don't do any good.

In other words, before applying the codes and rules, the people designing, installing, servicing, and testing the fire alarm system have to understand electronics and have to understand how life-safety aspects affect the electronics. Without this understanding, trying to match the design, the installation, the testing, and the servicing of a fire alarm system to all the varying codes is difficult, if not impossible.

Understanding the System

Once the down-to-earth layout and wiring of a working fire alarm system is understood, and how it relates to life-safety, matching the design, installation, testing, and servicing of the fire alarm system to the codes and rules becomes much easier.
