Editorial brief — draft. Start with how intrusion sensors detect different events and why a symbolic coverage shape is only a planning assumption.
Required method
- Mark perimeter openings, assets, approach/movement paths, interior boundaries, pets/processes, HVAC sources, glass conditions, and environmental risks.
- Select a preliminary detection method and mounting zone for each objective.
- Draw coverage or protected-point notation with model/height/orientation assumptions.
- Document cable path, conductor, panel/module, power, service access, and zone schedule reference.
- Plan walk testing, adjustment, false-alarm review, acceptance, and as-built updates.
Original evidence
Create a plan showing distinct perimeter, volumetric, and point-detection examples, plus a cable/zone schedule and a corrected false-alarm risk.
Review
Use current manufacturer data and qualified field verification; avoid guaranteeing detection from a generic coverage graphic.
