Thanks Wirenuts- Learn something new every day. I don't claim to be a fire alarm technician and the technology changes so fast in that field it's hard to keep up. Sounds like the big issue between Class A and Class B in the economics. The design professional will design the job as cost effective as he/she can.

The beauty of this Board is we all learn from others experiences. Nobody gets upset with being in error. (I hope)
