Auto Fan Control System
The Larkin AFC, A smart microprocessor based automatic fan activation system
  • Larkin’s third generation Auto Fan Control System (AFC) is a ETL listed, self-contained, full feature kitchen fan control center. The AFC system was designed specifically for compliance to the IMC code which requires the automatic activation and interlock of the exhaust and make up air systems. The Larkin AFC is designed for easier installation, less maintenance, and reliable performance. The newly redesigned system operates from a digital microprocessor control; its architecture is optimized for the continuous measurement of real-world analog signals from hood mounted sensor. the microprocessor uses an advanced smart logic model and sensor inputs to determine the state of cooking under the hood instead of simply relying on preset start/stop temperature setpoints and timers as most systems on the market do. The AFC’s advanced logic is capable of sensing and adjusting to temperature swings and can determine if the cooking equipment has been de-energized or just turned down to an idle state. This logic prevents unintended shutdowns, or the issue where some systems would shut down only to be re-energized by residual heat rise from de-energized cooking equipment. The microprocessor board is built with onboard means of field adjustment if needed. The temperature sensor is placed in the hood canopy for faster activation and easier cleaning. The AFC comes standard with a light control circuit relay capable of a 15amps (approx. 1800watts) of power, two sets of 15amp spare dry contacts for auxiliary equipment control and one 120v circuit for shunt trip breaker activation in fire mode. The system is shipped completely pre-wired in a self-contained wall mounted stainless steel enclosure with hinged access
