| Zusammenfassung: | A smoke detector for an air duct includes a photoelectric detection system and an air flow pathway in fluid communication with the air duct. The air flow pathway includes an inlet, an optic tube, and an outlet. The photoelectric detection system includes a circuit board having at least one light emitter and at least one light receiver mounted thereon. The optic tube passes through the circuit board and between the at least one light emitter and at least one light receiver. |
