I have an owner that has a large Data Center that is a co-location facility (multiple tenants lease the space in a Data Center). Some of the tenants are concerned about the EPO button being accessible to other people in that come in to work on their equipment.
I am trying to think of any way that an AHJ would allow a change to this and wanted to know if anyone has had any luck in the location of the EPO.
My idea is to install and EPO in the Main Security Office (Manned 24 hours a day) that basically has the has the functionality of the EPO for each computer room.
You could also make the EPO buttons in the Computer room only operational after a fire alarm event in the area has happened.
Looking for any thoughts on the above before I present it to the local AHJ.
645.10 Disconnecting Means A means shall be provided to disconnect power to all electronic equipment in the information technology room. There shall also be a similar means to disconnect the power to all dedicated HVAC systems serving the room and cause all required fire/smoke dampers to close. The control for these disconnecting means shall be grouped and identified and shall be readily accessible at the principal exit doors. A single means to control both the electronic equipment and HVAC systems shall be permitted. Where a pushbutton is used as a means to disconnect power, pushing the button in shall disconnect the power.
Thanks,
