Wissens-Bereich: zehn Fach-Artikel zu Normen und Planung

Der Wissens-Bereich führt neben den Ortsseiten jetzt frei zugängliche Fach-Artikel: Überwachungsfläche und Melderabstand nach DIN VDE 0833-2, Rauchwarnmelder in Wohnungen (DIN 14676-1), Meldergruppen der BMA und der EMA, Feuerwehr-Laufkarten, Schutzumfang-Kategorien, Deckenhöhe und Melderwahl, Dachschräge und Wandmontage, SAA-Schalldruck sowie EMA-Überwachungsarten und Grade — jeweils mit häufigen Fragen und dem Hinweis, dass alle Werte Planungsorientierung sind.

NEW
Rauchmelder-Rechner: Wie viele Melder pro Raum?

Neuer kostenloser Rechner unter /rechner/rauchmelder: Breite, Tiefe, Deckenhöhe und Dachschräge eingeben — Melderanzahl und Positionen werden nach den Vorgaben der DIN 14676 berechnet und live auf einem Grundriss gezeigt, mit offen erklärtem Rechenweg.

IMPROVED
Navigation: Rechner statt IFC & BIM, mehr Platz auf dem Telefon

Die Hauptnavigation der Website führt jetzt direkt zum kostenlosen Rauchmelder-Rechner (neuer Punkt „Rechner“ hinter „Wissen“); die Seite IFC & BIM bleibt über den Footer erreichbar.

Funk-Geräte auf einen Blick: Funkwellen-Kennzeichen im Viewer
