What? That should not increase the cost at all, and is required in most areas. All you need to do is get a shunt trip breaker and you are all set. I was able to build my colo in Atlanta with the shunt trip off the main 600 Amp 3 Phase panel. In doing this the USP still protected the load, but V/AC and lighting was shutoff. I think I spent $100 more for the shunt trip. The breaker is what cost us the big bucks, but not as much as the 800 Amp 3 Phase breaker on the UPS output. > I haven't looked at this recently, but another Fairfax County practice was > if you used halon, regardless if the room was also sprinklered, you had to > do a live test with halon before the inspector would approve it. The Ya, and you had to hold the test for a specified time without any air/halon leaking out. If you are building a new POP, HALON in ANY city is not legal any more. The bad news is there are still a few major areas that have not approved the HALON substitute. So you end up with a pre-action water system with high temp heads. -- Nathan Stratton Telecom & ISP Consulting www.robotics.net [email protected]
