Has anyone come across a dual riser (dual-feed) sprinkler system in an office tower, with only a single inspector's test?
What is the proper method of testing each flow switch?
In most cases, only the flow switch nearest the inspector's test will operate in a timely manner. Some inspectors will isolate and test, others believe the system should be tested under normal conditions with both control valves open.
Is the deficiency the lack of a second test connection, or that the flow switch doesn't operate within 90 seconds (or even 5 minutes)? Alternatively, is there no deficiency at all?
