How did we come up with those percentages? Look at Figure 2 (above right). With Panel Inter- face Modules (PIM) that average 12 doors per PIM, note all the blank spaces versus a wired system. With a wireless system, you avoid such hardware as the reader, lock, DPS, REX, electronic strike, reader interface module, door wiring and other equipment, replacing all with wireless access control cylindrical locks with proximity system and the PIM. Wired cost is $12,216.73 versus $12,923 for the wireless system.
ACCESS CONTROL EXPERT By Jennifer Toscano 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 tems to work from the get-go instead of having to and other equipment, replacing all with wireless tinker with them. When it comes to access control, access control cylindrical locks with proximity there are typically two options: wireless or hard- system and the PIM. Wired cost is $12,216.73 wired. Nowadays, the combination of wired and versus $12,923 for the wireless system. That’s wireless implementations is also quite common. close but wired looks like the better investment. For instance, in new construction, it is cost-effective Or does it? to install the wiring as the building is be- ing built. However, for vehicle entrances or 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 it takes to wire the building, the amount of sounding difference. To implement the wired sys- time saved runs between 75 to 95 percent. tem would cost $5,440 in lab
