This is an electrical engineering drawing prepared by Buffalo Engineering, P.C. for the Buffalo Public Schools (BPS) fire pump replacement project at BPS 97 - Harvey Austin Elementary School, located at 1405 Sycamore Street, Buffalo, New York. The document provides electrical single line diagrams and fire alarm riser details for the fire pump replacement work. The project involves disconnecting and removing the existing fire pump system, including the existing 400-ampere main circuit breaker and MI cable feeder with three #2 AWG conductors, and replacing it with new equipment including a 450-ampere main circuit breaker and new fire pump feeder. Additionally, the work includes disconnecting and removing the existing jockey pump and controller, and installing a new jockey pump with associated controls. The scope also encompasses modifications to the fire pump controller and automatic transfer switch, with new wiring and supervisory signal requirements. All electrical work must comply with applicable codes and manufacturer specifications, and the fire alarm system modifications must meet NFPA 72 functional testing and system verification requirements.

The drawing is dated August 29, 2025, and was prepared by Buffalo Engineering, P.C. under firm authorization number 020076 with a license expiration date of August 31, 2026. The electrical modifications involve working with existing 480/277-volt three-phase four-wire systems, including coordination with a 250-kilowatt natural gas emergency generator and existing automatic transfer switches. The fire alarm riser detail indicates integration with the existing addressable fire alarm control panel with voice evacuation capabilities, requiring extension and reworking of existing conduits and installation of new wiring throughout. All modifications to initiating devices, notification appliances, and control equipment must be functionally tested in accordance with NFPA 72 standards, with revised records of completion prepared to document system changes and verify correct operation.
