Your Enterphone is secured to the wall by four screwson concrete. For maximum strength, choose a location where all four screws can be anchored in wall studs. If this is not possible, at least two screws MUST be anchored in wall studs, with the remaining two screws using the supplied drywall anchors. If your installation site does not permit at least two screws to be anchored in wall studs, please contact your Identiv sales rep to discuss alternative solutionsconcrete or the substrate the panel is being mounted on. There are 4 x 1/2" holes in the base of the Kiosk and all 4 should be used to secure the panel to the ground. Typical installation is in concrete; use a 1/2" x 5" (minimum 4" depending on the thickness of the concrete) concrete anchor.
Use an anchor suitable for the material they are mounting it on, and make sure they use all 4 mounting holes.
