The interesting thing about the EPO and data centers is it wasn't orginally for life-safety, but came out of a recommendation by IBM to the NFPA for property protection.<<

Fwiw, the EPO on IBM's mainframes back in those days, had to be -pulled- and had a mechanical 'latch' that kept it from being pushed back in. Took both hands to reset it. --Michael
