How this tool helps

Use this to plan access control material quantities and power supply sizing before BOQ finalization.

Assumptions and limits

This tool provides a planning-level result. It does not replace detailed engineering design, approved software, manufacturer data, authority requirements, or project specifications.

Typical use cases

Early estimation and tender support.
BOQ sanity checking and technical review.
Site discussion before final engineering verification.
Comparison of alternatives using consistent assumptions.

Result interpretation

Read the recommendation, warning, and confidence sections together. A result without warnings is still not an approval; it only means the entered values did not trigger built-in planning alerts.

Calculation methodology

Door quantities are converted into controllers, readers, locks, power supply current, and backup battery Ah.

Inputs are treated as planning assumptions. The calculator shows warnings when entered values fall outside practical thresholds or selected standard-profile limits.

Version history

v1.3.6-prelaunch: Added methodology, standard profile support, version notes, and direct PDF report download.
v1.3.5: Calculator page added with sample data, warnings, and print-ready report layout.

Stage 2 roadmap: optional saved projects, dashboards, and shared calculation history without forcing login for free use.

Trust and verification

Every result includes assumptions, warning logic, and a downloadable report. Final engineering decisions still need qualified review, local authority approval, manufacturer data, and project specifications.
