System Sensor ETX Tube
The System Sensor ETX Tube is a vital metal exhaust duct tube engineered for precise smoke and gas detection within HVAC air handling systems. Designed specifically for smaller applications, this duct smoke detector accessory is compatible with duct widths up to 1 foot (12 inches), ensuring proper airflow transition to the sensing chamber. Integrating a System Sensor exhaust tube into your duct smoke detector installation is essential for maintaining NFPA 72 compliance, as it allows air to exit the detector housing back into the ventilation stream after sampling. Fabricated with durable metallic construction to resist high-velocity turbulence, the ETX exhaust tube provides a reliable, rigid path for sampling air. This component is compatible with standard System Sensor InnovairFlex series detectors, including the D4120 and DH100ACDC models. For contractors handling HVAC fire safety upgrades, using the correct exhaust tube length ensures accurate sensor readings and prevents false alarms caused by improper pressure differentials.
Key Benefits for Technicians- Durable Construction: Heavy-duty metal build prevents vibration and structural failure in high-velocity HVAC ductwork.
- Precision Fitment: Optimized for duct widths up to 1 foot, eliminating the need for field modifications or cutting in tight spaces.
- Airflow Efficiency: Facilitates correct pressure drops across the sampling chamber for accurate smoke and gas detection.
- System Compatibility: Seamlessly integrates with the System Sensor InnovairFlex line for rapid field replacement.
Can the ETX tube be used with any duct size? No, the System Sensor ETX is specifically designed for ducts 1 foot or less in width. For larger spans, an ST series sampling tube must be selected based on the duct diameter.
Is this tube required for the detector to function? Yes, a discharge or exhaust tube is necessary to create the pressure differential required to pull air through the detector’s sensing head.
Does the ETX require a specific orientation? Yes, the exhaust tube should be installed downstream from the sampling tube to ensure a consistent flow profile through the sensor housing.
