Who should maintain a mechanical smoke extraction system?

Maintenance of a mechanical smoke extraction system (MRA) must only be carried out by qualified technicians and authorized specialist companies. They must possess the necessary technical expertise, manufacturer-specific training, and knowledge of the relevant guidelines (such as VDMA 24186-1) to ensure safe operation and proper documentation.

What documents are required for maintenance?

For a complete inspection and maintenance, you need the object-specific fire protection concept, the functional matrix (cause-and-effect matrix), the system's operational logbook, and the manufacturer's specific maintenance and operating instructions. Only then can target and actual states be correctly compared.

What measured values and functions are documented?

The MRA functional check specifically records the startup times of the fans, volume flows, motor current consumption, triggering via smoke detectors and manual release buttons, and the automatic switchover to the emergency power supply. Feedback from the smoke extraction and fire dampers to the control unit is also logged.

How are identified defects tracked?

Identified defects are prioritized in the log, documented with photos, and linked to specific repair measures. The maintenance supervisor defines deadlines and responsibilities for resolution. After the repair is completed, a documented re-inspection is performed to approve safe operation.

1. Capture Order and MRA System Data

Professional documentation begins with the clear assignment of all property and system details. Before you start maintaining the mechanical smoke extraction system, record the specific key data of the installation as well as the legal and operational foundations.

This includes manufacturer details, system types, and assignment to the respective smoke extraction zones. By comparing this data with the fire protection concept, the functional matrix, and the existing inspection logbook, you ensure that the functional check is tailored precisely to the object-specific requirements.

Recording of object, system area, and individual inspection number
Documentation of manufacturer, control type, and smoke extraction zones
Verification of the presence of the logbook, functional matrix, and maintenance instructions

2. Inspect Control and Power Supply

The control unit is the brain of any smoke extraction system. If the power supply fails or the control unit reacts incorrectly, the entire system remains ineffective in an emergency. Therefore, this area forms a core part of the MRA maintenance log.

Check all housings, cable routes, visual and acoustic operating indicators, and the switching equipment for the emergency power supply. Seamless documentation of these system components provides operators with the assurance that the system will be reliably triggered in the event of a fire.

Inspection of cable routes for damage and proper installation
Testing of the emergency power supply (battery systems, emergency generators) for functionality

3. Document Fans, Airways, and Interfaces

The heart of mechanical smoke extraction is the fan system. During the smoke extraction fan inspection, all mechanical and electrical measured values must be precisely recorded. The template allows you to input repeatable measurement data for each fan and smoke extraction zone in a structured format.

This includes documenting flow velocities, volume flows, startup times, and electrical current consumption. At the same time, the interaction with the supply air routing, manual release buttons, and interfaces to the fire alarm system (FAS) is evaluated in detail during the functional test.

Inspection of airways, damper positions, and supply air replenishment
Functional check of interfaces to the FAS and manual triggering devices

4. Evaluate Defects and Track Repairs

If deviations or defects are detected during the maintenance of the smoke extraction system, they must be documented and evaluated immediately. Structured defect management is crucial to minimize liability risks for operators and service contractors.

Use the integrated photo documentation to provide direct visual proof of defects. Each required repair measure is assigned a priority, a clear deadline, and a responsible person, ensuring that the status remains fully traceable until a successful re-inspection.

Prioritization of repair measures based on urgency and safety relevance
Definition of deadlines, responsibilities, and documentation of the resolution status

Was ProtocolHero zusätzlich für dich übernimmt

Eine Vorlage allein ist erst der Anfang – ProtocolHero macht aus jedem Protokoll einen durchgängigen digitalen Workflow mit KI-Unterstützung, Workflow-Freigaben und revisionssicherem Archiv.

HERO Assistant – KI-Chat für Dokumentenerstellung

Der HERO Assistant ist der eingebaute KI-Chat von ProtocolHero. Du kannst per Spracheingabe ein komplettes Dokument anlegen lassen oder ein bestehendes PDF, Foto oder Word-Dokument hochladen – die KI liest die Struktur aus und baut eine wiederverwendbare Vorlage daraus.

Auto-Fill aus Sprache, Foto und Datei

Beim Ausfüllen kannst du das Dokument per Sprachsteuerung diktieren – die KI ordnet die Inhalte automatisch den richtigen Feldern zu. Oder du lädst Fotos, Scans, Verträge, Datenblätter oder Ausweise hoch: Der HERO Assistant extrahiert die Daten und befüllt das Formular vor – du prüfst und unterschreibst.

Foto- und Video-Upload direkt im Dokument

Zu jedem Bauteil, Messpunkt oder Schadensbild kannst du Fotos und Videos direkt aus der App anhängen. Videos sind besonders nützlich, wenn ein Schadensbild dynamisch ist – ein einzelnes Standbild würde den Befund nicht ausreichend dokumentieren.
