About this file
This document is an electrical engineering design sheet (E-512) for the United States Military Academy at West Point, NY, detailing various electrical infrastructure and lightning protection installation specifications. The sheet includes multiple technical diagrams covering ductbank conduit details, lightning protection installations for rooftop equipment (RTUs and exhaust fan air terminals), and a duct smoke damper wiring diagram. Key technical details include conduit schedules showing active and spare electrical service feeders, concrete envelope specifications (4000 PSI concrete, #4 deformed bar reinforcement), minimum burial depths of 36 inches, and specific requirements for conduit spacing and markers. The document is part of a project with solicitation number W912DS19C0034QPK, dated 13 May 2025, for repair of Building 606, with the US Army Corps of Engineers as the designing authority.

1. FIRE ALARM SYSTEM TO CLOSE SMOKE DAMPER UPON
ACTIVATION OF DUCT MOUNTED SMOKE DETECTOR, AND SEND
SIGNAL TO DDC SYSTEM SO BAS SYSTEM WILL SHUT DOWN FAN
SYSTEM.
2. BAS SYSTEM SHALL SEND SIGNAL TO FIRE ALARM SYSTEM WHEN FAN
SYSTEM IS TO BE ENERGIZED. FA SYSTEM SHALL OPEN ALL SMOKE
DAMPER. AFTER A TIME DELAY, DDC SHALL START FAN SYSTEM.
3. WHENEVER DDC SHUTS DOWN A FAN SYSTEM (IN A NON-FIRE
RELATED SITUATION), THE DDC SYSTEM SHALL CLOSE ALL SMOKE
DAMPERS.
