The Sparco 4.25 litre plumbed in electrical fire system. Part number 014772EXL.
This is the largest of the Sparco plumbed systems we carry, and capacity is the reason to choose it. More extinguishant means a longer discharge, and in a big cabin or a car with a large engine bay that is what you want. Some regulations also specify a minimum capacity by vehicle type, so read the wording rather than assuming a smaller bottle will do.
Specification
A steel bottle filled with AFFF foam based extinguishant, electrically activated, approved to FIA Technical List 16 and to MSA standards, for closed cockpit saloon cars.
AFFF is effective on fuel fires, which is what you are actually protecting against in a competition car. It leaves a residue that needs cleaning up, which is a problem you would be glad to have.
What to check first
Technical List 16 systems are accepted in a great many series and not in all of them. A number of championships now require FIA 8865-2015, which sits on Technical List 52 instead. Read your own regulations before you order, because this is the most expensive thing to get wrong in a build.
Check the packaging as well. A 4.25 litre bottle is a substantial thing and it has to be mounted where a belted in driver can reach the actuator, with an external pull for a marshal. Both are scrutineered, and so is bottle orientation.
Most regulations that require a plumbed system also require a hand held bottle. Tell us the class and we will make sure you have both.
What is the difference between mechanical and electrical systems?
How you set them off. A mechanical system fires by pull cable from the cockpit, an electrical system fires from a button that can sit anywhere and adds an external trigger point for marshals more easily. This is the electrical version. Both plumb into nozzles around the engine bay and cockpit.
Is it accepted by scrutineers?
It carries FIA Technical List 16 Approved, MSA Approved status. Extinguisher requirements are set per discipline, including capacity and whether a plumbed system is required, so check your regulations for the exact requirement and ask us if you want us to match a system to your series.
Does it need servicing?
Yes. Extinguishers carry a service date and need periodic servicing to the manufacturer schedule, which scrutineers do check, so factor a service into your running costs and note the date on the bottle when it arrives.
Can I install it myself?
A competent home builder can: the work is mounting the bottle securely, routing the plumbing to the nozzle points, and rigging the trigger. The instructions cover the layout, and we can advise on nozzle placement for your car if you tell us what you are building.
