Brahma Photocell FC11/A 18209003

The Brahma FC11/A is a flame sensor that uses a photocell to detect the presence of a flame in burners and air heaters. It has a cable length of 800 mm and is designed for use in specific Master models, including 4033.246, B230, B360, BV110, BV170, and BV290, from 2013 onwards. This component is essential for flame monitoring and safety shutdown in combustion systems.

When selecting a replacement flame sensor of this type, ensure that the detector type (photocell) and cable length match the original part. The sensor must be compatible with the burner model and control system. Installation typically involves disconnecting the power, removing the old sensor, and connecting the new one, ensuring proper positioning to detect the flame accurately.

Common failure modes for photocell flame sensors include a dirty or damaged lens, which can cause false flame detection or failure to detect the flame, leading to burner lockout or shutdown. Symptoms may include the burner failing to start, intermittent operation, or the system repeatedly resetting. Check the sensor for soot or debris and verify its electrical continuity.
