At NDT Electronic Services we design and manufacture X-ray & Gamma Enclosure Safety Systems.
Our safety systems comply with industry standards, IRR1999, EN13849 & EN62061

The ISIS safety system is a radiographic compound monitoring system. Its role is to inhibit/cease X-ray/Gamma radiography in the event that: The compound access doors are opened, an emergency stop is activated or a warning sign (Annunciator) has malfunctioned and display the status of the X-ray/Gamma machine connected to the system.

The ISIS Safety System features dual safety circuits and complies with the following standards:  EN ISO 13849 with an achieved performance level Ple, BS EN 62061, SIL3, Iionising Radiation Regulation 1999.

Its constituent parts are:

The central point and ‘brains’ of the system, all peripheral devices connect to the Interlock Unit.

NDT-safety-system-interlock-unit

Three stage LED illuminated warning sign displays the status of the X-Ray/Gamma system connected to the Interlock Unit. Each Annunciator features LED failure detection circuitry and an automatic test function. Up to 5 signs can be fitted to the system.

NDT-safety-system-annunciator

A waist height “grabwire” emergency stop that runs along the inner perimeter of the compound that allows personnel to manually stop the X-Ray/Gamma system from within the compound. Up to 5 Lifeline Emergency Stops can be fitted to the system.

NDT-safety-system-emergency-stop

A magnetically coded, non-contact, maintenance-free switch to be fitted to the compound doors. The door switches fail to safe in the event that the connecting cables are short or open circuit. Up to 4 ISIS Door Switches can be fitted to the system.
