Prerequisites and tools needed for a compliant audit
Successfully completing an IEC 62305 compliant audit requires, first and foremost, a thorough understanding of the IEC 62305:2024 and NF C 17-102:2011 standards. These standards define the protection levels (LPLs), the areas to be protected, the electrical continuity requirements, and the mandatory inspections. Without this knowledge, it is impossible to validate the critical criteria during the inspection. Each installation must also comply with the IEC 50164 standard for individual components.
In terms of equipment, you will need specialized hardware tools. For communicating installations ( Paraton@ir ), the Contact@ir + Rout@ir system allows you to manage up to 999 devices in real time with alerts and historical data. This architecture offers a range of 300 meters using 868 MHz RF and stores data locally before uploading it to the cloud. For spot checks, Contact@ir + Dongl@ir covers 80 meters without requiring internet access, ideal for remote sites. Contact@ir MD uses an international eSIM for monitoring via 4G/3G/2G cellular networks, sending alerts immediately and data every 12 hours. For non-communicating Ellips , Test@ir performs wired diagnostics.
The LPS Manager application centralizes all management. It logs diagnostics, generates compliant reports, triggers real-time alerts, and archives data for regulatory traceability. Editions vary: Free for basic folder creation and alerts, Data (€2.99/month) for detailed history, Pro (€9.99/month) for unlimited reports, Expert (€29.99/month) for branding, and Enterprise (price upon request) for API and BMS/SCADA integration. The 2026 Lightning Protection Criteria, Architectures, and Recommendations guide details these architectures.
Before any intervention, verify physical access conditions. Secure high-risk areas (roofs, pylons), prepare appropriate PPE, and identify site constraints. For multi-site industrial installations, map the equipment to be audited. Understand the fundamental difference: Contact@ir Ready communicating equipment allows for continuous remote monitoring, while traditional lightning rods require systematic physical intervention. To secure lightning protection infrastructure , combine field inspection and telemetry.
Pro tip: Prepare a summary table before each audit listing equipment reference, date of last verification, number of recorded impacts, and status of the last diagnosis. This speeds up the identification of anomalies in the field.
| Tool | Main use | Range/Connectivity | Recommended Architecture |
|---|---|---|---|
| Contact@ir + Dongl@ir | On-the-spot mobile diagnosis | 80m RF, USB Android | Isolated sites, scheduled inspections |
| Contact@ir + Rout@ir | Continuous multipoint monitoring | 300 m RF, Wi-Fi/Eth/mobile internet | Industrial sites, multi-building |
| Contact@ir MD | Cellular autonomy without infrastructure | 4G/3G/2G eSIM | Multiple dispersed sites, restricted IP network |

Practical steps for auditing a lightning protection system
1. Document preparation and device configuration
Begin by gathering installation plans, compliance certificates, maintenance history, and previous audit reports. Create or update the file in LPS Manager by registering each Contact@ir Ready device with its serial number and certificate of authenticity. This step activates warranties and history tracking. Configure Rout@ir receivers or mobile applications according to the chosen architecture. Verify RF or cellular network coverage in critical areas.
2. Detailed visual inspection of lightning rods, conductors, and grounding
Physically inspect each lightning rod. Check for corrosion, deformation, loose connections, or signs of impact. Verify the continuity of the down conductors along their entire length: fixings, welds, and fittings must comply with minimum distances and standard cross-sections. Examine grounding connections, equipotential bonding, and recent soil resistivity tests. A visual inspection is necessary but insufficient ; a functional diagnosis is required for complete verification according to IEC 62305.
Consult the detailed guide to lightning protection components to identify critical parts.
3. Wired testing with Test@ir for non-communicating equipment
Ellips installations without a communicating module, use Test@ir with a direct wired connection. This tool checks the functional status and detects internal electronic faults. Record the results immediately in LPS Manager with photos and observations. For residential sites seeking to protect their homes against lightning , this periodic check ensures effective protection.
4. Real-time diagnostics with Contact@ir + Dongl@ir, Rout@ir or Contact@ir MD
Activate diagnostic reading via the LPS France app (Dongl@ir) or Rout@ir. Contact@ir transmits a self-diagnostic status every 100 seconds. Rout@ir displays real-time multi-transmitter status when connected to the internet; otherwise, it displays it via Bluetooth on-site. Contact@ir MD sends data every 12 hours plus immediate alerts with no latency. Verify product authenticity, photovoltaic battery status, system temperature, and last communication. Any anomaly triggers an immediate alert.
5. Analysis of impact counters and alerts with Compt@ir and Alert@ir XT
Record the number of lightning strikes logged since the last audit. Compt@ir displays a 6-digit cumulative total of positive and negative impacts. Alert@ir XT operates without a display but transmits alerts via Contact@ir System as soon as an impact ≥ 1 kA is detected. Compare LPS Manager historical data to identify abnormal increases indicating equipment degradation or increased exposure. The NF C 17-102 standard mandates verification after each impact.
Ensure protection of installations against overvoltages by also checking associated surge arresters.
6. LPS Manager logging and generation of normative reports
Record all observations, measurements, and photos of defects in the LPS Manager folder. The application automatically generates IEC 62305 compliant reports with timestamps, geolocation via Google Maps, and a complete event history. Export to PDF/HTML depending on the recipient (client, insurer, certification body). Share read access with rodholders.
7. Next proactive maintenance planning
Set the date for your next annual regulatory audit. Activate LPS Manager proactive notifications for early warnings. If impacts are detected, schedule immediate targeted verification. Establish a maintenance log with scheduled interventions, replaced parts, and ongoing compliance validation.
Pro tip: For multi-site installations, deploy Rout@ir in a mesh architecture to cover large areas. Position the receiver in an unobstructed location to maximize the 300-meter RF range and reduce obstructions from concrete structures.
Common errors and solutions during an audit
Post-impact audit omitted
The most critical error: ignoring mandatory verification after a lightning strike. Compt@ir and Alert@ir XT, equipped with Contact@ir System, send automatic alerts as soon as an impact is detected, triggering a verification workflow in LPS Manager without any human delay. Installing these meters eliminates this oversight.
Confusion between local diagnosis and extended supervision
Many auditors use Dongl@ir thinking they can obtain historical data and remote alerts. Dongl@ir only offers spot readings within an 80-meter radius, without recording. For continuous monitoring, Rout@ir or Contact@ir MD are required. Clarify your architecture before the audit. The 2026 Lightning Protection Guide: Criteria, Architectures, and Recommendations compares these options.
Lack of security for accessing data and devices
LPS Manager implements access control based on owner rights for folders and secure redundant servers. On the ground, secure Rout@ir on a dedicated VLAN segment with outbound filtering. Contact@ir MD uses eSIM with an encrypted cloud connection. Require complete security documentation (TLS, certificates, IAM) for sensitive enterprise deployments.
Lack of systematic logging in LPS Manager
Neglecting systematic logging in LPS Manager can compromise traceability and invalidate evidence of compliance. Establish a strict procedure: all interventions, measurements, and observations must be recorded immediately with timestamps and photos. Enable automatic cloud synchronization to prevent local data loss. See lightning protection compliance steps for recommended workflows.
Underestimation of log and associated maintenance plan
Auditing without updating the maintenance plan renders the audit pointless. LPS Manager includes a planning module with automatic reminders for annual checks, post-impact inspections, and certification renewals. Link each piece of equipment to a preventive maintenance schedule. For critical installations (telecoms, data centers), schedule semi-annual audits.
Pro tip: Create a custom digital checklist in LPS Manager that includes all IEC 62305 control points specific to your installation types. Check them off in real time on your field tablet to ensure completeness.
Expected benefits and success indicators of an audit
