Frequently Asked Questions
What is a kitchen gas interlock system?
A gas interlock system prevents gas from flowing to appliances unless ventilation is running correctly — protecting against fire, fumes, and gas accumulation in kitchens.
Is a gas interlock system required in commercial kitchens?
Yes. In both New Zealand and Australia, gas interlock systems are recommended or required under AS/NZS 5601.1:2022 when there’s no flame failure device or where ventilation is critical.
What’s the difference between current monitoring and air pressure systems?
Current monitoring systems (like the Merlin CT1650+ and CT1250X) monitor fan power draw, while air pressure systems use switches to detect airflow. OGS offers both types depending on your fan setup and preference.
Are OGS systems easy to install?
Yes — our systems are designed for easy integration with existing extraction and gas systems. We provide technical support and can connect you with certified installers via All Controls.
How quickly can a system be installed?
Most systems can be delivered quickly and installed in a single day, depending on your kitchen setup and location. All Controls provides nationwide distribution and support in NZ and Australia.
