This document is a detailed labeling guide for fire alarm device installation, specifying device numbering conventions for wall-mount and ceiling-mount configurations. The guide provides systematic device identification methods using abbreviations like WM (wall mount), CM (ceiling mount), SP (speaker), MSP (mass strobe/speaker), and F (fire strobe), with corresponding device numbers starting at 1 for each device type and location. The notation includes various mounting and device combination scenarios such as wall-mounted speakers, mass strobes, and fire strobes, with a clear instruction that each device type number shall start at 1. The document appears to be a technical reference for standardizing fire alarm system device labeling across different installation types and locations.
