Moitoring controllers (not the FINs) are required for all Independent parallel approach operations, i.e. where traffic may become side by side. (As opposed to Dependent Parallel approaches, where they don't).
Where the runway spacing is less than 1310m but not less than 1035m,
"...suitable SSR equiment, with a minimum accuracy of 0.06 degrees (one sigma), an update period of 2.5 seconds or less and a high resolution display providing position prediction and deviation alert..." must be available.
That is PRM.
So, you must always have monitoring controllers, and must also provide a PRM if the spacing between the centrelines is less than 1310m.
