Emergency Utility Isolation Systems for Critical Environments

OGS utility shut-off systems are designed to automatically or manually isolate gas, water, and electrical supplies in the event of an emergency or fault. Whether triggered by a fire alarm, gas leak, or panic stop button, these systems help prevent accidents, mitigate risk, and keep facilities compliant with AS/NZS 5601.1:2022 safety requirements.

Commonly installed in school laboratories, hospitality venues, aged care kitchens, and boiler rooms, our utility shut-off panels are built to perform under pressure — with rapid activation, clear system feedback, and seamless integration with other Merlin safety products.

Supplied across New Zealand and Australia via our trusted distribution partners, OGS offers compliant solutions backed by expert support and a 3-year warranty.
