The video says that MLSD increases the cost of solar systems. Does this even matter when it comes to the safety of our first responders?
The video goes over a range of unintended consequences of the MLSD requirement, one of which is increased cost. However, the major portion of the video talks about the safety issues caused by the requirement, which increase the risk of fire in the first place. It also highlights that current solutions are unreliable because of electrical noise levels, so fire fighters cannot even rely on them, putting them at actually higher risk. Thus, if cost would be the only unintended consequence while actually increasing the safety of systems, then we would not have to fix the code. However, the current situation has too many unintended safety consequences and thus needs to be fixed. This is what the video highlights.
