"Whether a contractor, AHJ, insurance guy- we ALL have to keep up with what is available to us- and the restrictions on them-"
ROFLMAO - good luck with that. Even those that try I think are falling behind quick. Especially, on the AHJ side. Not because they can't but because they have alarms, building code, hazmat etc. to also stay on top of. Alarms probably change twice as fast as sprinklers. Not to say one shouldn't try. As fast as things are a changing I sure wish I was 60 not 40. Chris Cahill, P.E.

Sounds like threaded pipe and standard spray heads are all that would be allowed due to the ability to screw up all the other stuff that in many cases is either required (unless you design your building away from needing them) or has demonstrably proven better fire protection (Attics, CMSA, ESFR). Whether a contractor, AHJ, insurance guy- we ALL have to keep up with what is available to us- and the restrictions on them- in order to provide the best protection levels and most economical installations for our customers. Dumbing down because of the reality we face is defensible- I understand you build for a multi-generation building that will have dozens of sprinkler guys <and plumbers, maintenance men> working on the systems over the decades- but isn't necessarily the answer outside your market niche in the other 90% of the industry. The vast majority of our customers are very price sensitive and in most cases, the bang for the buck is what gets called as the play to run. glc _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field)
