Now is a great time to review your property’s life safety system’s inspections!
Property management comes with great responsibility. One of those responsibilities is fire safety, and remaining educated about the fire protection systems in your facility. Some of the most common mistakes arise when your systems are not tested and inspected according to NFPA standards and/or your local AHJ (Authority Having Jurisdiction).
When properly maintained and inspected, fire protection systems are among the most reliable means to ensure the safety of your building and everyone in it. Trusting that your systems will optimally perform in the event of an emergency depends upon the quality of the service and inspections performed on them. When you work with Protegis Fire & Safety, you get the full-scale capability of one of the most established and experienced fire protection companies in the United States.

If you’re a general contractor, and your job is to provide fire protection to valuable equipment such as data centers, computer servers and computer rooms, then this post will help you understand why there is no definite price per square foot for a clean agent fire protection system.
First, we need to
understand how a clean agent system works, and how this will throw a wrench
into how much the system will cost.
Fire needs three elements to burn: heat, fuel and oxygen. By removing any one of these, the fire will not burn.
So, once a computer room starts sending signals of a fire (usually from smoke), the smoke detector will signal an alert for the clean agent system to start releasing its gas, which will eliminate the oxygen the fire needs to burn. The reason a computer room would use a clean agent system as opposed to a water-based system, is that water will damage the electronics.
So now the question
is, how much clean agent will I need for the system to work? And how much will
How much clean agent will you need?
Very different than a fire sprinkler system, where all you worry about is how much floor space you need to cover, the amount of clean agent you will need is determined by volume, not by area. But just because your computer room is 20×20 ft., doesn’t mean you need enough clean agent for 400 sq. ft.
There are plenty of variables that will determine the price of your clean agent system.
What variables will determine the price for a clean agent system?
If there is a
sub-floor, the height is added to room in factoring the total volume for agent
calculation. Additional detection devices are installed in the subfloor,
typically matching the ceiling layout.
2) Ceiling Void
If there’s a space
above a ceiling void being used as a return air path (without duct work),
additional agent and detection are required.
The number of doors
affects the area because you must account for additional manual pull stations
and abort switches, which not only includes cost in equipment, but also cost in
labor for installation.
Are dampers controlled
off of releasing panels with relays? If so, dampers must close shut at
discharge to maintain the integrity of the agent per volume.
5) Ceiling Height
This dimension is part
of the overall volume calculation. If the ceiling height increases, more
agent is needed. If it decreases, you may be over concentrating from your
One of the most asked questions our special hazard technicians get is “how much per square foot is a clean agent system?” After this post, I hope it’s clear there is no definite price per foot for a clean agent fire protection system. There are just too many variables that can apply.
