RFI IDs 33-36 Images_Compressed.pdf

This document set consists of photographs of HVAC (heating, ventilation, and air conditioning) equipment and control systems, supplemented by technical specification documentation.

The images depict industrial HVAC infrastructure including: a gray metal electrical control panel with a "Danger - Electrical Hazard" warning label mounted on corrugated metal decking; internal wiring diagrams and control components featuring Siemens temperature sensors and control modules; Ebtron digital transmitters with "EB-Link Inside" capability mounted in stainless steel enclosures with caution labels; fire protection system piping and valving; a Nailor Industries single duct terminal unit rated at 24 volts with a diamond flow sensor calibration chart dated September 4, 2001 (Model D20RW, Serial No. 147055-114); and various pressure gauges, transformers, and interconnected electrical components. Technical documentation includes equipment specification sheets showing control voltage of 24 volts DC, 60 Hz operation, and dimensional specifications for inlet sizes of 14-12 inches. The equipment incorporates multiple Siemens monitoring devices, terminal units with analog displays, and integrated fire protection systems marked with appropriate safety warnings. The infrastructure appears to be part of a larger building mechanical system with both supply and return air handling capabilities.
