Carbon Monoxide Detector Annotation Symbol

This Revit family is a standard 2D annotation symbol for a carbon monoxide detector, designed for clear electrical plan documentation. The symbol consists of a simple octagonal frame containing the letters CMD, identifying the carbon monoxide detector in architectural and electrical floor plans. It is a clean, minimalist 2D graphic designed to maintain legibility across various scales. The geometry is strictly flat, intended for use in documentation views rather than 3D modelling. This family uses standard Revit line work and text parameters, ensuring it remains crisp when printed or exported to PDF. It provides a consistent visual language for safety equipment placement throughout a project's technical drawing set.

The download is a 184 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.

Load this RFA file into your project as a generic annotation or electrical device tag. Once loaded, it can be placed directly onto floor plan views to indicate the location of detection hardware. Users can modify the family's text size or line weight within the family editor to match specific office standards or project-wide graphic overrides. It is ideal for MEP coordination and life safety plans where clear, unambiguous symbols are required for building code compliance and contractor reference.

This symbol is essential for residential, commercial, and hospitality projects during the construction documentation phase. It belongs on life safety, electrical, and reflected ceiling plans where detection devices must be clearly marked for building inspectors and site teams. Professionals typically pair this with fire alarm and smoke detector symbols to maintain a uniform documentation standard. Use this in any project requiring strict adherence to fire safety regulations, ensuring that all detection points are accurately represented in your final drawing submission.
