I would like to open up a topic to this amazing forum.
Preaction systems...types, cost, challenges, panel set-ups...I continue to see the vast lack of knowledge amongst the design and management community.
Which type is best? Which is more economical? Which is best for your company to install or to maintain? How does a double interlock system affect design/cost? Can a single interlock system be set up to operate the way you need and at a lower cost? Does the AHJ typically have any special requests?
Knowing these answers could only make everyone's lives easier. Thanks in advance!
