Mike-
Try to convince your company officer/inspector to include the power room in any future tours, if only for "familiarization" purposes.

We make it a point to require labeling on the outside of the doors of the rooms containing the Main electrical D/C, main gas valve (if inside), the fire pump (if equipped), sprinkler system shut-off and drain, and the main fire alarm panel.

In addition, we require the occupant to provide zone maps for their alarm system to be posted by the annunciator, and have the above indicated on the map.

Just my $0.02
