N2 Bldg 2000 Phase 6 Drawing FA.pdf

This document is a Mass Notification Upgrade specification for SAXC 14-1006 at Cheyenne Mountain Air Force Station, Colorado, specifically for Building 2000 - Node 2.

The scope encompasses the design and installation of a comprehensive fire alarm and mass notification system for Building 2000. The project includes upgrading the existing fire alarm control panel (BLD 1600, N11) and installing BACnet-integrated amplifier loads, backup power supplies, battery calculations, and speaker circuit configurations across multiple rooms (2103, 2101, 2211, 2309, 2301, 2203, and other designated spaces). The system incorporates Signaling Line Circuit (SLC) loop integration with detailed address lists for all connected devices. Technical specifications include intelligibility and auditability testing baselines, correct wiring methods for Class "A" wiring standards, and device identifiers for proper installation. The documentation provides comprehensive battery calculations for multiple Battery Power Supplies (BPS #1 through #14) with associated voltage drop calculations for each room location. Detailed acoustically distinguishable space diagrams illustrate coverage areas, and general notes address fire alarm system operational requirements, ADS declaration legends, equipment mounting elevations, and symbols legend with bill of materials. Architectural and electrical coordination drawings show Building 2000 roof plan and cross-section details including cable routing and system interconnections across the facility's first and second floors.
