Bank interlock system saves dollars - literally


Securitron has teamed up with a number of companies on a high-security bank interlock system that makes life hard on bank robbers and ensures that a bank’s money stays where it should – in the bank.

The interlock system allows the bank to control who enters and exits its premises. There are usually two side-by-side compartments with two doors at opposite ends of each compartment. One compartment allows customers entry into the bank, and the other permits them to exit.

To get into the bank, customers first walk into the entrance compartment, passing through the outer door then standing on a specialized electrified door mat, which detects their presence and locks the inner door into the bank.  Customers then pass through a metal detector – with both compartment doors locked – before they are allowed into the bank.

Exiting is accomplished using a standard two-door interlock, in which customers cannot unlock the outside exit door until the inside exit door is locked behind them. Bank employees can lock all the doors in order to either prevent access to the bank or to trap a subject in the exit compartment.

The bank interlock system is commonly used in environments where bank robbery is a common problem, such as South America. But in the last decade, the technology has migrated north and is now used in several large cities in the United States, as well as in Europe.

The interlock doors are locked using Securitron M62 Magnalocks with TSB touch sense bars for egress. “The mat system, metal detector, Magnalocks and Touch Sense Bars all tie into a Bank Interlock Panel,” explains Mark McBroom, Securitron Exhibit Coordinator. The entire system is powered by a Securitron BPS series power supply.

Bill Diaz, president of NovaComm, which provides the security panel technology, says: “Partnering with Securitron allowed our company to provide a much needed solution for our South American customers. This innovative solution allowed our companies to solve a customer problem and maintain a high level of security and life safety in the process.”
