Awhile back I mentioned there were some big projects in the works around here. This has been Number 1 on my list for over a year now.
Last summer I threw out an idea that took hold, and since last November I've been thrilled to be a part of a project that I think will be a major help for industry professionals.
The National Fire Sprinkler Association (NFSA) has published informal opinions on everything fire sprinklers for longer than I've been alive. Their Expert of the Day program answers real questions to the 'gray' areas of code with practical advice from leading industry experts.
While these opinions have been collected and published monthly for decades, up until now they've never been assembled, organized, and published into a single resource.
I'm thrilled to announce that this collection of expertise is now complete; the NFSA Expert of the Day Handbook is a two-volume, hardcover set of over 1,300 pages covering nearly 2,000 questions on over 585 topics relevant to fire sprinkler systems, standpipes, water supplies, inspection, testing, maintenance, codes and standards.
Why am I so thrilled about it? I had the pleasure to work with NFSA by collecting, converting, and organizing all the expert inputs into these volumes. This was a concept I really wanted to see happen - and after sharing the idea of compiling the years of content to NFSA they were happy to fold me into the team on this project.
It's now available for pre-sale with shipments starting in just a few weeks (late August / early September).
If you are a sprinkler designer, engineer, inspector, installer, plan reviewer, code authority, or work in and around the fire sprinkler industry, then this handbook was built for you.
Just in the eight months of reading and compiling the information I saved days of code research (thousands of dollars in billable hours) by having quick access to these expert opinions. Just as it is part of the mission of this site, I am wholeheartedly excited to see how these handbooks help promote best practices and share expertise with the industry.

Determining the correct height of a fire sprinkler relative to structure and ceilings or roofs is not typically a difficult task. Yet, the more I explored the basic premise the more I realized how different the needs for each sprinkler type are.
This week I've been working on a cheatsheet for fire sprinkler deflector heights. It's a flowchart that helps direct the sprinkler height and code reference based on the type of sprinkler. Click here to download a PDF copy.
If you find cheatsheets like these helpful, consider subscribing to free tools like these here.
Take a look and let me know what you think. Thanks & have a great week!
I hope you are having a great week.
This week is a 2020 update to a popular post from 2016 with a free PDF cheatsheet. It's usefully for novice designers or experienced inspectors, with clear code references and purposes of each of the components that go into a floor control assembly serving a fire sprinkler system.

Last week I introduced a Remote Area Analyzer that evaluates remote area size and shape.
This week could possibly be the biggest and best expansion of any tool created thus far. I'm thrilled to present a beta version of our Sprinkler Estimator tool.
With a few default adjustments, you can quickly get a remote area's pressure and flow demand, remote area shape, and have a live schematic of the calculation that updates without a need for "re-running" the calculation.
For a long time now I've wanted a tool where I could quickly estimate pipe sizes and a remote area's demands before I started laying out the system so that I could be as efficient in my design workflow as possible. What typically takes me 30 minutes to a couple hours can now be gathered in less than 30 seconds.
Another fun application? Want to see what effect k-factors have on your calculation? What about long sprigs? Or what about pipe schedule changes? Wet versus dry systems? What about a consistent branch size versus changing pipe diameters? With this tool you can adjust parameters with just a click and see the live impact it has on your calculation.
I'm really not trying to hard sell this one, I've just had my morning coffee and I'm thrilled to have you give it a try. It's been something I've thought about and developed piece by piece for a couple years now.
The best way to experience it is with the downloadable version of the Toolkit. You can get a free 30-day trial of that here, or download the latest full version here. The downloadable version has a split-screen that shows the live preview and live calculated results while also allowing you to adjust parameters... no scrolling required.
Click here to give it a try on our cloud version, and shoot me an email at firstname.lastname@example.org if you have any feedback or suggestions.
Thanks and I hope you have a great week!
When I initially set up a hydraulic calculation for a tree-style sprinkler system, there are a few key points I have to consider. All of these points today and the tool are specifically for tree systems (not gridded).
First, we need to determine what the remote area actually is. In NFPA 13, for instance, there are multiple adjustments (quick-response sprinklers, dry systems, sloped systems, high-temperature, etc.). Even if we start with a 1,500 sqft remote area, it could look a lot different after multiple adjustments.
Second, we need to determine the minimum length of the remote area along a branch line. This is a relatively straightforward at 1.2 x √ (remote area size), but it's still another hand-calculation that needs to take place.
We then round up to determine the sprinklers along the first branch line, then expand by branch lines to figure out how many sprinklers are actually in a calculation.
The tool I'm introducing today (which is also now available on the Toolkit) is a schematic-level remote area analyzer that will apply multiple adjustments and quickly estimate the important parameters associated with a remote area.
With only a few quick inputs, you'll see an initial remote area laid out with a live schematic of your situation. Click either of the images below to give it a try:
A new remote-area analysis tool which incorporates adjustments and gives a live schematic layout. See it here.
If you already have the toolkit, you can download this and three other recently added tools in today's Toolkit update here. If you're interested in giving this tool a try, check it out here. I'll have it up without any login credentials for a couple months.
In time, I'm looking forward to expanding this tool to have some powerful estimating abilities.

A Hurting World at Large
Just like I don't ask hollywood to be my moral compass, you don't come here for my my personal opinions. I get it. That said there has been a tremendous amount of unrest here locally, nationally, and worldwide this past week.
I think there's a major feeling that our collective perspective has to improve. I want to do better and be part of a better future for everyone. I want you to know that whoever you are and wherever you are, I very much care about you and your well being. You have tremendous value. Hope you and yours are safe, healthy, and doing well.
Thanks & I hope you have a great week.
Did you know there are over 1,500 variations of sprinkler models which are actively on the market today?
Around three years ago we began development on one of the largest research projects we've ever undertaken - organization of all the fire sprinklers available on the market today. It took several hundreds of hours to finely comb through all the k-factors, pressure listings, spacing distances, model numbers, responses, and links to websites and product data.
The Comprehensive Fire Sprinkler Database
In late 2018, we finally released it - a comprehensive Fire Sprinkler Database. With it you can search by SIN, k-factor, type, spacing distances.... most any parameter you need to in order to find the sprinkler that's the best fit for your design.
The introductory video to it is here (forgive the terrible voice narrator... it was me): https://www.youtube.com/watch?v=DsLPg4GKaCU
Updates from This Week
Just this week we've updated the database to include recent releases for new sprinkler models from Tyco, Viking, and Reliable, including new window sprinklers, concealed sprinkler options, MRI sprinklers, institutional sprinklers, and corridor sprinklers.
Use It Today
If you haven't checked it out - here's an opportunity to do so. I've opened it up for everyone just for the next couple weeks. Just go to this link - www.meyerfire.com/sprinklerdatabase - and login using firstname.lastname@example.org as the username and sprinklerdatabase as the password if you're not already a Toolkit subscriber.
The Fire Sprinkler Database is the most current and comprehensive database of available fire sprinklers across all manufacturers we know about. Click the image to login and try it out.
For those in the inspection department - it's been asked how we can take this to the next level.
Can we get obsolete and recalled sprinklers into the database as well, so that we can quickly search to find information on recalls? That answer is yes, but I need your help. I'm not regularly involved in inspections, but I know many of you are.
If you have a good understanding of where all the various manufacturers recall information (old and current companies) and how I could best showcase that material, please reach out to me at email@example.com. I'd be happy to get some input on how I can tackle this next phase of the database and make it that much more useful for us all.
Thanks & have a great week!
While couped up in our house I've been binging on creating cheatsheets instead of Netflix. Sorry Tiger King.
This week I'm debuting an overview of the components for seismic bracing in fire sprinkler systems. Seismic bracing is a nuanced and complex topic, but my hope with this overview cheatsheet is that you'll have a starting point for reviewing all the different requirements that go into seismic bracing.
As always, be sure to check the code, the commentary, and any other information you can find on these topics to make sure your work or your reviews are top notch.
That being said, here's the two-page introductory cheatsheet for seismic bracing in sprinkler systems under NFPA 13. If you find this content helpful, please considering sharing with colleagues and subscribing to resources like this here: www.meyerfire.com/subscribe.
Thanks and have a great rest of your week!
A couple weeks ago I sent a sprinkler obstructions cheatsheet for the options with standard spray sprinklers and ceiling-mounted obstructions where the sprinkler cannot throw over the obstruction.
Thanks to some great suggestions, I've now incorporated some visuals that might help. As always, thanks for the feedback! You can download the updated cheatsheet here:
A New, Free, Fire Protection App
In case you missed it last week - there's a new free fire protection app on the market.
It's free and was developed by Michael Swahn and the helpful engineers over at Sebench Engineering out of Atlanta. It's now live on both Google Play Store and the Apple App Store. Here's links to get it:
Google Play: https://play.google.com/store/apps/details?id=al.pragmatic.sebench.android
The app has quick-calculations for Fire Pump Tests, Hydrant Flows, Equivalent K-Factors, Flow/K-Factor/Pressure Calculations, and Friction Loss. Download it today with the links above.
NFSA Expert of the Day Handbook Coming Summer 2020
One of the major projects I've been working on since last fall is development of the National Fire Sprinkler Association's Expert of the Day Handbook. It is a two-volume hardcover compilation of thousands of informal interpretations by NFSA's Experts, spanning 2004 through 2018.
The set will be available through NFSA later this summer (likely by July). I'm thrilled to be a part of compiling these in a searchable, organized manner that could very well be the go-to resource for suppression design, inspection & testing outside of the standards themselves. There will be plenty more on this as the book becomes available for sale, but wanted to share a little of the good news on this exciting undertaking.
Thanks & I hope you have a safe and great rest of your week!
There are a handful of rules in NFPA 13 covering how sprinkler protection works in and around obstructions. It's for good reason; we don't want objects getting between a growing fire and our best method of suppressing it.
The PDF cheatsheet this week covers options for throwing water below obstructions, where the top of the obstruction is at or above the sprinkler deflector, for standard pendent and upright sprinklers.
If the sprinkler deflector has the ability to throw over the top of an obstruction - different rules apply - which we'll get to in the coming weeks.

Today is a very big day for me. I am finally launching the start of an idea I've had and brainstormed and discussed and revisited for a number of years now.
Finally. I could not be more excited about it.
Ever since the COVID-19 pandemic began impacting the world around us I've been pressed to rethink my own operations and what I'm contributing to the world. Articles, design content, PE Prep, and trying to find ways to help the knowledgebase of the fire protection community is good, but I started the website around the idea of impacting the community in a real and tangible way.
Today's new project is the start of what I hope could be a major positive impact for AHJs, designers, and installers.
What is it? A Code Call Database.
What is CodeCalls.org?
CodeCalls.org is a free website that is bringing together local jurisdictions, fire protection designers, engineers, and installers to clarify and collaborate local code requirements.
We're taking the areas of code in fire protection design that need local input, and helping jurisdictions get what they need to help first responders do their work.
When we're done, we plan to have a searchable, filterable database where you can find local requirements based on a project's ZIP code, city or county name.
Where to Start? Indiana!
There tens of thousands of jurisdictions in the United States alone, how is all this data going to come together?
First, we're starting with our test case. If you work in the State of Indiana or have contacts who do, pay close attention today.
Our Goal is to gather jurisdictional requirements for 70% of Indiana's population by May 8th. That's in 30 days.
Indiana has a healthy mixture of urban, suburban and rural jurisdictions, so it presents a great test case to validate the concept. If we get enough momentum for Indiana, we feel confident in pursuing the project for larger coverage.
If we find that we can get enough momentum to clarify requirements for Indiana, then we feel that the project could be viable to expand to new areas beyond Indiana and beyond just the United States, too.
Why a 70% Coverage Goal?
In order for the database to work, the user experience has to be great. Both for jurisdictions and for designers & installers. We feel that if we can cover jurisdictions that account for at least 70% of the area's population, that we'll have enough data for a great user experience and a very helpful resource.
Is it Free?
Yes, the database will always be free for anyone to access. We're funding the development efforts as a joint project by MeyerFire.com and BuildingCode.Blog.
Why Should I Help?
If you're an engineer, designer or installer, why should you contribute?
For one - this is a way to clarify local requirements that will help in more fair and consistent bidding.
Second - we'll thank you by crediting your contribution with a link from the local listing directly to your company's website. If someone is looking for a local contractor or design outfit, they can search a ZIP code and immediately have contact information to you, the person who they know is already familiar with the local requirements.
If you're a jurisdiction, why should you contribute?
Simple - get your needs met. Are you tired of providing the same plan-review comments? Tired of answering the same basic questions in phone calls and emails? This platform is an easy way to clarify the gray areas of code and simply make your requirements more clear to those who are seeking them.
I Have Some Information for Some Areas in Indiana. How Can I Help?
You can contribute information for jurisdictions you're familiar with here. We'll thank you with a promotional link to your company's website and help get the information verified by the jurisdiction.
