Do you have to do a hydrostatic test of an automatic dry standpipe based on the 2017 or 2020 edition of 25? 6.3.2.1 calls out the hydrostatic test of manual stadpipes and semiautomatic dry standpipes; no mention of automatic dry standpipes. Under the definitions, the difference is that the semiautomatic uses a deluge valve with pull stations or some control device to activate the system. The automatic uses a dry valve and opening the valve operates the system. It doesn't make sense that you would test one type but not the other. What am I missing?
