Calculate the Savings—Wired versus Wireless
                  INTEGRATORS WANT SIMPLIFIED offerings                  hardware as the reader, lock, DPS, REX, electron-
               that are easy to use and install. They want the sys-      ic strike, reader interface module, door wiring

               there are typically two options: wireless or hard-        system and the PIM. Wired cost is $12,216.73

               buildings on the perimeter, it would be ad-
               vantageous to use wireless access control. In
               aftermarket applications, an integrator may
               combine wired openings for the perimeter
               and wireless access on the interior openings.
                  From a dollars and cents standpoint, it’s
               easy to determine whether you should be
               promoting wired, wireless or a combina-
               tion of the two for your upcoming job.
                  By analyzing Figure 1 (below), let’s de-
               termine costs for an 11-story building of
               830,000-plus square feet with 15 access
               points per floor. In the fourth column are the
               savings with wireless. For instance, there are
               83 percent less SKUs, 99 percent less wire
               and 91 percent less connections. Depending on the           Looking at the labor, you will discover a re-

               time saved runs between 75 to 95 percent.                 tem would cost $5,440 in lab
