A duct detector may include a detection chamber and a control circuitry stacked vertically on top of the detection chamber. A sealing gasket may seal a contact between a substrate of the control circuitry (e.g., the seal may be at the bottom surface of a printed circuit board containing the control circuitry) and the detection chamber such that particles analyzed the detection chamber may not damage the control circuitry. Therefore, by providing a sealed barrier between the control circuitry and the detection chamber, the sealing gasket allows for stacking the control circuitry and the detection chamber. As the seal does not create a barrier (the barrier is for the detection chamber) for a repair personnel to access the control circuitry, repairs to the duct detectors may be easier because the seal may not have to be broken and resealed during the repair process.
