How to install and connect the unit Be absolutely sure to read through the "Read this first!" (page 5) and "Installation precautions" (pages 6 to 7). The procedure given here is for the kind of installation where the unit is suspended from an overhead surface, but the same steps are followed for a stand-alone installation. If the ceiling panel is not strong enough to bear the unit's weight, use the kind of mount bracket that is supported by anchor bolts between the concrete ceiling and ceiling panel. The unit supports the WV‑Q105A direct ceiling mount bracket which is used solely for combination cameras. Use this bracket to install the unit. (See page 12.) In a case like this, the holes (ø 60 mm [ø 2-3/8 inches]) for installing the direct ceiling mount bracket on the ceiling must be drilled in the ceiling panel. It is also recommended that you provide an inspection space or opening for access purposes in the area near where the equipment is installed in order to facilitate installation and the wiring connections work. See page 36 for details of the accessories. 1 Check the mounting space. ●● Refer to the illustration, and determine where the unit is to be installed and in which direction it should be mounted.
