Editorial brief and template specification — draft. Explain that symbol meaning comes from the visible project legend, not from shape alone, and that local/customer standards may differ.
Reference structure
- General symbol rules: distinct geometry, readable size, contrast, orientation, and identifiers.
- Discipline tables for cameras, access, fire/life safety, intrusion, cabling, network, AV, home theater, POS, VoIP, and smart systems.
- Legend fields: symbol, name, abbreviation, mounting/location note, count rule, schedule key, and revision.
- Examples of ambiguous symbols and corrected alternatives.
Original evidence
Extract and verify the actual 43-symbol Plan Studio inventory before presenting product symbols. Create a printable neutral legend and an annotated plan showing how legend, label, and schedule connect.
Safety control
Fire/life-safety examples require qualified review and must not be presented as a universal code legend.
