I just recently dealt with a similar situation. We took over an account that contained a preaction system in a computer server room that had not to the customers knowledge ever been tripped (thus the reason they left the competitor). The customer had no idea of what a preaction system was or how it functioned. After explaining it to them they asked that we not do a trip test for the same reason your customer is. All we did was make a note on the tag that all switches were tested but valve was not tripped. We noted it on the report and made sure the customers request was written down in the report also. After the request was recorded i had the customer sign by the request verifying that they made the call. Then we shut the system down and did the internal inspection. I believe that this was the most logical solution that would minimize the liability to the company in which i work for. After this was all done I asked our attorney and he concurred that even though code says one thing, we have to look at the customer needs and liability. The customer was very happy with the way this situation worked.
Hope this helps a little. Jeremy S.

We do limited trips on a quarterly basis and full trips once a year. Tom For those of you doing inspections, how do you handle preaction systems? 13.4.3.2.3 says that they should be trip tested fully open every three years similar to dry systems. We don't inspect a lot of preaction systems, but all of the owners have not let us do a full trip, they are afraid of water leaking out of the system on to their equipment.
