A fire sprinkler head anti tamper canopy discourages hanging objects from a sprinkler head, or otherwise tampering or accidentally activating a sprinkler head. The canopy encloses the projecting portion of a sprinkler head, at least around the sides of the sprinkler head, and allows heat to enter and activate the sprinkler head, and water to escape from the sprinkler head for fire suppression. The canopy is magnetically secured to the wall or ceiling surface, without a requirement for physical attachment to the sprinkler head. Upon sprinkler head activation, water pressure dislodges the canopy, the latter returnable to an anti-tamper position once the fire sprinkler system has been reset.
