FM approval for diesel fire pump controller

2017 NEC

695.15 Surge Protection. A listed surge protection device

shall be installed in or on the fire pump controller.


While doing a plan review, I wrote a correction requiring the surge protection as stated in NEC (above).  I'm being told by the general contractor that "FM approval" will not allow for surge protection on a diesel fire pump controller, and that this would void the FM approval.  Does anyone that is more familiar with FM approval agree with this, or am I being given another line of BS?


Thanks in advance.
