When a hazardous gas level is detected, the controller processes sensor signals and triggers alarms, notifications, and safety actions to protect people, equipment, and facilities.<\/p><p data-start=\"1195\" data-end=\"1535\">At Instrava, we offer a versatile range of gas alarm controllers designed for accuracy, reliability, and integration with advanced gas detection systems.
