Kirk Key Interlock Company

Trapped Key Interlocks for Perimeter Guarding - Monitoring and Testing

Our access interlock product range provides solutions to guarding applications by only permitting access once a specified operation has been completed, most commonly shutting off the power. An optional time delay unit adds functionality through denying access to the equipment or area until any residual power has completely stopped, ensuring safe access. Our access interlocks integrate seamlessly with any other KIRK®interlocks already in place, providing you with a complete system. Perimeter guarding has many different uses and advantages, from protecting against dangerous live machinery to enabling access to multiple components at once, as long as they have the same prerequisite sequence. An example of this would be a capacitor bank.
