Which cable type is specified for two hours of direct fire exposure?

Explanation:
Cables used in fire alarm circuits have fire-resistance ratings that specify how long they can withstand direct flame exposure. When a requirement calls for survive two hours of direct fire, you need a cable that is explicitly rated for that duration. The FPLP-CI variant is designed for a two-hour direct-fire exposure, making it the appropriate choice to meet that requirement. The other variants carry different ratings or are intended for different conditions, so they wouldn’t satisfy the two-hour criterion. Always verify the exact rating from the manufacturer or the applicable standard, but for a two-hour direct exposure need, this variant matches that spec.
