In the UK cables for fire alarm systems etc should be able to resist fire for long enough for people to evacuate, typically cable that can resist fire for 30 minutes is used.
I doubt that your systems are cheaper than fire resisting cable, so I can't see that most buildings would need your systems.
I doubt also that if some coyboy had installed a system without fire resisting cable, that the cheapest solution would be to then retrofit your system, the best thing to do would be to put in a system with the normal 30-minute resisting cable.
Depending on how long your systems can resist fire, places where the consequences of loosing a cable are very expensive - perhaps critical IT systems, might have a need for the system - but generally if there are mission critical IT systems, for example banks, they will have a separate hot start facility off site. The simple solution would be to avoid runing cables through high fire risk areas. Further to that, if a building has a large fire, it won't just be the cables that are damaged, it will be the structural integrity of the building and many other systems. The focus of risk management professionals will tend to be to avoid the fire in the first place (good housekeeping, elimnation of ignition sources, control of flammables etc etc) then reacting quickly to a fire (fire extinguishers, sprinklers, fire alarms to summon the fire service).
I expect there is a market for your product, but that it is limited. The typical factory or shop isn't going to need such a complex system.
I think the focus in petrochemical places will certaily be to avoid fires in the first place. A fire in such a place would be biger than 5MW. Likewise in a storage depot.
Good luck. I think you need to establish who you need to sell to. If you need to market your product, us folks tend to read Fire Prevention journal.
