One of the most frequently asked questions from our customers is "How many turnstiles do I need?" For obvious reasons, this is probably the most important question a customer can ask when it comes to purchasing or renting a Patented Modular Access Control (MAC) Portal from Modular Security Systems Inc. (MSSI). Not enough turnstiles can mean employees’ work time is wasted by traffic jams at the entrance to the plant or the project. When people are trying to access your project and are unable to do so in a timely fashion, a lack of respect for management may occur, and this may cause tension on the jobsite. In contrast, too many turnstiles can mean a significant waste of financial resources which could be saved or used on other aspects of your project or plant infrastructure.
In order to determine just how many turnstiles you will need in your patented MAC Portal, first and foremost you will need to calculate the number of employees that will be working on your project. Construction workers at industrial plants or on construction projects tend to work on a strictly organized and ordered shift basis. In order to comply with these strict schedules, employees must be accommodated with the highest possible throughput per turnstile per minute. At the same time that you are trying to get workers in and out of projects during shift changes, it's also important to be able to track their time for time-keeping and payroll purposes. This leads us to a second frequently asked question: "What kind of access control technology do I want to use?"
There are a wide range of access control solutions you can use in your Patented MAC Portal. Choices range from simple access card readers to RFID scanners, to biometric readers like hand-geometry units, IRIS eye scanning devices, and vascular readers that scan the vein structure in the back of an individual’s hands. Depending on the solution you choose, these access control technologies can generate reporting for time-keeping, payroll, and mustering reports in the event of an emergency.
In addition to knowing the number of employees and the type of access control technology you want to use, you will also need to figure out how much time you'd like to devote to your employees’ shift changes.
Once you know how many workers you will have on your project, the type of access control technology you want to use, and how long shift change will be, determining the number of turnstiles you will need in your patented MAC Portal is simple – as simple as inputting all of those data points into our Turnstile Flow Calculator.
The Turnstile Flow Calculator here at www.SecuredByMAC.com may be used to determine precisely the number of turnstile lanes you will need. As a demonstration, we will run through a couple of examples in this week’s Turnstile Blog.
Using the Turnstile Calculator is simple. All you have to do is enter the number of employees you'll have on your project and the amount of time you're allowing for shift change in the "shaded boxes" and the calculator does the rest.
In this first example we imagine a 500 person work force with a 15 minute shift change. Given that information and the speed with which access control technologies handle the number of people that they do in a "per minute" ratio, we are able to determine that five turnstiles (or a patented MAC-5) are needed for this example.
In the second example we picture a 1000 person work force with a 20 minute shift change. Given the new figures, we see that six or seven turnstiles would be needed depending on the access control technology you chose to use.
The third example shows that eight or more turnstiles will be needed.
We here at Modular Security Systems Inc. are determined to help you resolve any and all perimeter security concerns on your major industrial and commercial construction projects. We hope that the Turnstile Flow Calculator we've provided here is helpful and easy to use, but if it's not and you'd like some help from us determining how many turnstiles you will need, simply CONTACT US and we'll be happy to help!
