RE: [EXTERNAL] Re: Captive Aire Systems

[Phil Stoehr via Sprinklerforum]

Every few months we get a GC asking us to hook up to these systems, we 
“politely” refuse.

The manufacturer’s literature is vague, installation requirements can be 
expensive (reduced pressure backflow, low maximum pressure limit, pipe sizing?, 
inspection/testing requirements?), and we’ve had Captive Aire submit these for 
permit under our contractor number without permission.  After trying to 
facilitate installation on a couple projects, we’ve determined it’s not worth 
the hassle.

In a roundabout way, that sort of answers your question. If they aren’t allowed

stands to reason that they shouldn’t connect to sprinkler systems that are

I’ve run into these on multiple projects. They go by the name Captive Aire, 
Core and Pirhana.

They have a pressure demand of 32-70 psi and a flow rate of about 40 gpm 
depending on the number of nozzles. We see these in Marriott properties often.

They can be off domestic or fire as I see it. They are supposed to be direct 
line as was described to me yesterday. So they can’t have sinks or other 
fixture coming off the line supplying them. Doesn’t make sense why it can 
attach to sprinkler then. But none of the suppliers will state if we have to 
flow this simultaneously with sprinklers.

Re: [EXTERNAL] Re: Captive Aire Systems

[AKS-Gmail-IMAP via Sprinklerforum]

It is definitely a challenge to get down to the details for these systems to 
determine the implications for “supply its water from the automatic sprinkler 
system”. I don’t think the system nuts and bolts details are easily available 
online for inquiry. I have seen the installation and controls diagrams for such 
an existing system, which probably was tucked into the control cabinet or 
pasted to its access door. It had two water supply connections. One was for 
cold water and one was for hot water. 

These hot and cold supplies connected to electrically operated valves. The 
control panel switched the water supply between cold and hot as needed for the 
suppression mode and the wash down mode. In this part of the country connecting 
the cold supply to the automatic sprinkler system meant there are two possible 
water supply cross contamination avenues. One is the automatic sprinkler system 
crossing into the kitchen hot water system which may not have had an RPZ back 
flow preventer on its supply line. The other avenue is the wet chemical 
suppression agent somehow backing into the sprinkler system, thus requiring an 
RPZ back flow preventer between the sprinkler system and its water supply. 

New Zealand sounds like it may be sophisticated in its rules regarding these 
systems so that the question regarding supply from the automatic sprinkler 
system is not one that opens a can of worms.

Further to Nicky’s comments I would add that the systems installed as tail end 
to fire sprinklers do not have the hood washing feature that the Captive Air 
appear to have. 

Pressure reducing is needed in some cases.

In New Zealand, we frequently connect them to a sprinkler system as the 
installation of an approved ‘restaurant system’ permits sprinklers to be 
omitted from ducts and hoods in our standard.

We do not allow a cumulative demand.  Although our standard does not explicitly 
state what you should do.

When connected to a sprinkler system they are treated much like a ‘tail-end’ 
pre-action or dry system.  Because sprinkler system compliance is dependent on 
that system, they are connected with a supervised/monitored valve to warn if 
closed and they also usually have a flow or operation switch on them that 
indicates on a fire alarm panel.

Our suppliers also do the calculations.

I was told that they can’t have the connections to toilets or sinks upstream 
because it could take water away from the system when needed.  But, in this 
case they finally came back and just took it from the domestic.  So I won’t 
worry about it until the next one comes up.

Travis,

Like Bruce, I may be a few years out of date also but I've never seen one of 
these connected to a sprinkler system. They are for a special hazard and so 
independent of the life safety and building protection definition for a 
sprinkler system. These are designed to smother the fire with the saponifying 
agent and then use the water to cool down the appliances to avoid reflash. Way 
back in the nineties, this system was a way that Ansul came up with to meet the 
new requirements of UL 300. requirements that commercial cooking operations had 
to comply with even in unsprinklered buildings (think stand-alone McDonald's, 
Red Robins, etc, under 5000 or 6000 sqft that weren't required to be 
sprinklered then). Note that NFPA 13 isn't even referenced as an applicable 
code/standard.

CODES AND STANDARDS
The PIRANHA hybrid wet agent system and its components meet the following 
codes, standards and recommended practices:

Extinguishing Systems for Protection of Restaurant Cooking Areas.

2. Underwriters Laboratories, Inc. (UL): Standard 2092 – Pre-Engineered Wet

4. National Fire Protection Association (NFPA): Standard 17A – Wet Chemical 
Extinguishing Systems.

5. National Fire Protection Association (NFPA): Standard 96 – Ventilation 
Control and Fire Protection of Commercial Cooking Operations.

6. American Society of Sanitary Engineers (ASSE): Standard 1001 – Cross 
Connection Protection Devices: Guidelines for Selection of the Proper Type of 
Backflow Preventor – Piped Applied Atmospheric Vacuum Breakers.

7. International Association of Plumbing and Mechanical Officials (IAPMO): 
Installation, Material and Property Standard PS 108-98 – Grease Fire 
Suppression Systems.
