Fire Alarm System Plan for Cheyenne Mountain A.F.S. Building 3000 - Node 3

This document is a comprehensive fire alarm system plan providing detailed engineering specifications and design documentation for Building 3000, Node 3 at Cheyenne Mountain Air Force Station. The plan includes ten pages of technical drawings, calculations, and system specifications required for installation and operation of a multi-loop fire alarm system. The system incorporates multiple building protection squeeze (BPS) power supplies, an emergency communications interface, and addressable detection devices distributed across the building on seven separate signaling line circuits (SLCs). The fire alarm control panel (EST3) serves as the central hub, coordinating signals from smoke detectors, heat detectors, duct detectors, and manual pull stations throughout the facility.

The technical specifications encompass battery calculations for multiple power supply configurations in rooms 3104B, 3207, and 3303; voltage drop calculations across extended circuit runs to ensure adequate power delivery; detailed device address lists for each SLC loop showing sensor locations and types; and complete wiring schematics with device identifiers and circuit routing. The plan specifies Class "A" wiring configuration with redundant signaling paths for enhanced reliability. Supporting documentation includes beam ceiling height information, operational matrices defining device response protocols, smoke detector spacing criteria, project-specific notes addressing system-specific requirements, and general notes covering installation standards and compliance parameters. The system is designed to meet federal fire safety standards for a critical military facility with comprehensive coverage across multiple floors and functional areas of Building 3000.
