System for magnetic mounting and registration of sensors to grid ceilings

A system comprising:

• a detachable registration element:
• configured to couple to a grid segment of a grid ceiling;
• and
• comprising an engagement surface;
• and
• a mounting member:
• comprising:
• an upper face;
• an engagement feature;
• and
• a magnetic element extending above the upper face by a first height greater than a protrusion distance between a grid segment of the grid ceiling and an outer surface of a ceiling tile extending below the grid segment;
• and
• operable in:
• an installed configuration with the detachable registration element located on the grid ceiling, the engagement feature coupled to the engagement surface to orient the mounting member on the grid ceiling, and the magnetic element magnetically coupled to the grid ceiling to retain the mounting member on the grid ceiling in the installed configuration;
• and
• a service configuration with the detachable registration element located on the grid ceiling, the engagement feature decoupled from the engagement surface, and the magnetic element magnetically decoupled from the grid ceiling.
