EPO's

[mshields]

Having been convinced by several on the site that EPO's are not required, I have the following question. 645 requires a disconnecting means for all electronics and another for all HVAC. We always tie in the pre-action and ansul system to the EPO circuit. Is this interlock required anywhere?

Thanks,

Nope, unless the clean agent requires fan shutdown to maintain concentration in a particular area.
