I hate to make a decision or recommendation without knowing the whole picture, and on a forum such as this it's impossible. But a sprinkler system is such an integral part of the evaluation of a building, and occupancy, that it would be unlikely that the business would be allowed to stay open while the sprinkler system way out of service.
In addition to fire control, and usually invisible to the spk company, often fire alarm is required, independent of spk requirements. The flow switch required for spk monitoring is often in lieu of an automatic detection system. But this is an architect or project manager question.
