Happy New Year! Now that there is a lot of new construction going on, it is easy to put testing and servicing of fire alarms on the back burner. Since a number of companies will do just that, now is the best time for...
What will fire alarm systems of the future be like? Technology is changing rapidly, and historically, fire alarm systems have not kept up with these modifications. That is starting to change. In the 2016 NFPA 72, National...
There have been a few changes to the requirements for fire alarm system power supplies, and more are coming. This is a good time to review the ones we have so far. Obviously, since a fire alarm system is a life safety system,...

Happy New Year to all of you! Each year, I like to start out with a column on fire alarm changes for new editions of the codes. We begin with the 2018 International Building Code (IBC). As a reminder, the fire alarm...
In the last year or two, I have written a few articles about NFPA 3, Recommended Practice for Commissioning of Fire Protection and Life Safety Systems, and NFPA 4, Standard for Integrated Fire Protection and Life Safety...
As I teach fire alarm seminars around the country, one of the greatest problem areas brought up is interfacing fire alarm systems with elevators. Elevator and fire inspectors do not enforce the same codes, and therein lies...
We have all heard the phrase “That’s good enough for government work!” Whether said in jest, sarcasm or resignation, it implies you have done all you’re going to do, and the result will just have to suffice. In the world of...
