In many industrial settings, a standardised procedure for operating, maintaining or accessing systems is necessary. One way to ensure correct and safe operation on a site is by using the RONIS trapped key interlocking system by DOM Security.
For more than 50 years, RONIS Trapped key interlocking system helps companies to regulate safe operation on-site. This system, in form of a series of keys, are intended to enforce the safety regulation in high and medium voltage installations. These regulations are made not only to protect the personnel while working in a high and medium voltage environment but also to protect the installation from any false maneuvres which could lead to damage.

No limits & designed to last
RONIS Trapped Key Interlocking System is designed to last for generations to come. Our products offer no limits on combination or sequence.
Isolating is the first step of the trapped key interlocking system. Mechanical locks are used in this first step. In this important step, the power supply is switched off by turning the key from a latch bolt lock to the "power off" position. A system like this prevents staff from making accidental errors or taking unauthorised shortcuts around the established safe procedure. The same key will be used to execute the second step: exchange.
The second step is in the trapped key interlocking system is called "Exchange". In this step, the key obtained from the first step (Isolate) is used to start a customised sequence of trapped and released keys. This step is used to open more devices, and sometimes this step may cover up to 24 cylinders, depending on the complexity of the system.
