CMAFS Inter Tunnel FA As-Builts.pdf

This document is a Fire Alarm System Plan for Cheyenne Mountain Air Force Station, specifically for the Inner Tunnel - Node 1 facility. The plan provides comprehensive technical specifications and design details for the fire alarm system installation within Building 1000.

The document includes seven pages of detailed engineering drawings and calculations covering the complete fire alarm infrastructure. Key components detailed in the plan are: SLC (Signaling Line Circuit) loop address lists for four separate loops within Building 1000; fire alarm panel battery calculations; amplifier load calculations; APS (Auxiliary Power Supply) battery and voltage drop calculations for the chamber and inter-tunnel areas; and typical mounting elevations for various fire alarm devices. The system incorporates multiple detection zones with addressable devices, manual pull stations, speaker circuits, and interconnected wiring schedules. Technical details include Class "A" wiring configurations for redundancy and fault tolerance, device identifiers and symbols legend, correct wiring methods for single input monitor modules and signal modules, and smoke/heat detector wiring details. The plan specifies equipment mounting locations, power supply requirements with 4" x 4" gutters for the APS, and comprehensive device addressing protocols across the four SLC loops. Calculations confirm adequate battery capacity and voltage delivery for all operational scenarios. The document serves as the complete technical blueprint for implementing the fire alarm system at this Air Force facility location.
