The clause is a condition because it makes coverage dependent on the insured satisfying a specified obligation: having a sprinkler system installed and active in the kitchen at the time of a fire loss. Conditions are policy provisions that impose duties or requirements on the insured and may affect whether coverage applies if they are breached. Although the clause has a restrictive effect, it is not best classified as an exclusion. An exclusion removes coverage for a defined peril, cause, property, person, or circumstance. Here, the policy is not excluding all restaurant fires; it is requiring a protective safeguard as a precondition to coverage. “Subscription” refers to a situation where multiple insurers participate in a risk, not a policy clause of this nature. “Requirement” is a plain-language description, but the technical wording category is condition. Brokers must highlight these clauses to clients because failure to maintain protective systems can defeat an otherwise valid claim.
