Emergency Shutdown Solution

Manual Shutdown Relay With Added Gas Detection

AGS Mini Merlin

If there is a dangerous build-up of gas or unsafe levels of carbon monoxide at the sensor, this device can shut off the gas supply via a gas safety valve and/or a gas fire appliance. A code requirement in Florida, Georgia & Texas.

This device has additional features for resetting systems, as well as audible and visual alarms – it can also be integrated with a Building Management System (BMS). For further information on our Mini Merlin refer to our datasheets or alternatively contact our offices today.
