Detection loop voltage drops below required minimum due to high resistance, despite all devices being online and no apparent faults.

Existing diagnostics tools don't pinpoint the cause of high loop resistance; technicians rely on trial-and-error (splitting loops) or time-consuming manual testing.

Workarounds Described

splitting the loop into two to improve resistance
brute force meter testing (hella time consuming)

Implied Software Gaps

Automated loop diagnostics tool that identifies specific high-resistance sections without trial-and-error splitting
Mobile app for rapid fault localization without manual meter testing

App Concept

LoopMapper Pro

LoopMapper Pro is a diagnostic tool for fire alarm technicians that automatically analyzes detection loop resistance and voltage drop, pinpoints fault locations, and suggests corrective actions. It integrates with major panel brands and provides a step-by-step troubleshooting guide, saving hours of manual meter testing.

Key Features

Automatic loop resistance and voltage measurement
Fault localization to specific branch or device
Integration with major panel APIs (Mircom, Notifier, etc.)
Step-by-step corrective action recommendations
Mobile app with report generation

Target Users: Fire alarm technicians and service companies in the electrical industry, especially those maintaining large commercial or residential systems.

Revenue Model: $49/mo per technician subscription with a free basic tier, or $299/year with advanced analytics and multi-site support.
