: The difference between an upright head and a pendent head is, an upright sprinkler is designed to be installed upright in the branchline piping of a sprinkler system. The pendent is designed to be in the pendent or 6 o clock position, with the deflector facing downward. It is important that you always install sprinklers in accordance with their designed listing; you cannot install an upright sprinkler in the pendent position, for example. you can usually find this information with the data sheet supplied with the sprinkler. If in doubt, contact the sprinkler manufacturer. Sprinkler installation is regulated by National Fire Protection Association or NFPA for short, document number 13.. This standard gives the codes for proper location, selection, and installation of fire sprinklers.

It depends on the use of "pendent"you are refering to. In biology, "pendent"means loose or hanging in refering to a structure or organ so the antonym may be "rigid" or "erect". In law, "pendent" means "forthcoming" so the antonym may be "complete" or "past".
