Fontana FS-354AQ-DP Antique Commercial Automatic Sensor Faucet: Infrared Sensor Detection Zone Diagram

This infrared sensor detection-zone resource supports architects, plumbing engineers, specifiers, contractors, installers and facility teams coordinating the Fontana FS-354AQ-DP commercial automatic sensor faucet. The diagram identifies the active-infrared sensor window, sensor axis, hand-activation area, adjustable detection range, factory sensing distance, basin centerline, water-stream landing zone and potential reflective or interference areas that should be evaluated during installation and commissioning.

FS-354AQ-DP Active Infrared Detection System

The FS-354AQ-DP incorporates an active infrared sensing system within the faucet body to provide touch-free activation. The sensor projects a defined detection field toward the intended hand position beneath and forward of the spout. The detection range can be adjusted between 16 and 32 cm, while the supplied diagram identifies a nominal factory setting of approximately 25 cm. Final sensing performance should be confirmed after the faucet, basin and surrounding finishes are installed.

Required Infrared Sensor Detection Drawing Package

The sensor-detection drawing should establish the location and orientation of the infrared sensor window relative to the faucet body, spout, countertop and basin. Front, side and plan views should define the sensor axis, intended hand-activation envelope, adjustable sensing range, nominal factory setting and relationship between the detection field and water-stream landing zone. Reflective surfaces, accessories and other potential obstructions should also be considered before the final sensor setting is approved.

Infrared Sensor Detection Zone Diagram

Shows the complete sensing relationship for the FS-354AQ-DP, including the active-infrared sensor window, projected detection field, hand-activation area, adjustable detection distance, basin centerline, water-stream landing zone and reflective interference area.

Sensor Window Position

The infrared sensor window is integrated into the upper faucet body near the spout connection. Its orientation establishes the sensing direction and should remain unobstructed after installation.

Active Infrared Sensor Field

The sensor projects an active-infrared detection field forward and downward toward the user's intended hand position. Activation occurs when a suitable target enters the configured sensing zone.

Factory Detection Set Point

The supplied detection drawing identifies an approximate factory activation distance of 25 cm (10 in). This value serves as the initial sensing reference before site-specific adjustment and commissioning.

Adjustable Detection Range

The sensor range can be adjusted nominally between 16 and 32 cm (6.3–12.6 in). The final setting should provide reliable hand detection without creating unwanted activation from surrounding surfaces or nearby objects.

Hand-Activation Area

The intended hand position lies beneath and forward of the faucet spout within the projected sensing envelope. The detection field should permit natural hand placement while keeping the activation zone coordinated with the basin.

Sensor Axis & Plan View

The plan view establishes the sensor axis along the faucet and basin centerline and identifies the intended hand-position zone. Accessories or other obstructions should not project into this sensing path.

Basin & Water-Stream Relationship

Coordinate the faucet outlet, sensor axis and basin centerline so the user activates the faucet while the resulting water stream lands within the usable bowl area. Maintain sufficient clearance to limit unintended splash.

Reflective-Surface Interference Zone

Highly reflective basin surfaces or objects located within the projected sensor field may affect detection. The completed installation should therefore be tested with the actual basin, countertop and surrounding finishes before the sensor adjustment is finalized.

Engineering note: The infrared detection field shown is a coordination and commissioning reference and should not be treated as a fixed physical boundary. The nominal adjustable range is 16–32 cm, with approximately 25 cm identified as the factory set point. Confirm actual detection performance after installation using the completed basin, countertop, faucet position and surrounding finish conditions.

Sensor & Basin Coordination Considerations

Faucet-to-Basin Alignment

Align the faucet outlet and sensor axis with the intended basin centerline so user hand placement and water delivery occur within the usable sink area.

Hand Position

Position the active sensing zone where normal handwashing motions naturally enter the field without requiring the user to reach excessively toward the backsplash or drain.

Water-Stream Landing

Coordinate the detection field with the faucet outlet so activation occurs while the water stream lands within the bowl rather than against the backsplash, rim or countertop.

Reflective Surfaces

Verify sensor performance near polished, glossy or highly reflective basin surfaces. Adjust the sensing distance where necessary to avoid unintended activation or unstable detection behavior.

Sensor Obstructions

Keep soap dispensers, accessories, trim elements and other objects outside the intended sensor field and away from the direct sensing axis.

Final Commissioning

Test the faucet after the basin, countertop and surrounding finishes are complete. Confirm reliable hand detection, appropriate shutoff and absence of nuisance activation.

Infrared Detection System Components & Functions

Active Infrared Sensor The integrated infrared sensing system provides touch-free detection within the configured hand-activation range. Sensor Window The sensor window is positioned on the faucet body and establishes the origin and direction of the active detection field. Adjustable Detection Range The nominal sensing range can be adjusted between 16 and 32 cm to coordinate user activation with the installed basin and surrounding surfaces. Factory Sensor Setting The supplied technical drawing identifies an approximate factory detection set point of 25 cm (10 in) before final site adjustment. Basin Detection Relationship The sensor field should be coordinated with the basin centerline, intended hand position and water-stream landing zone for reliable touch-free operation. Reflective-Surface Verification Final installation testing should evaluate the effect of reflective basin and countertop surfaces on sensing performance before commissioning is completed.

Sensor Setup & Commissioning Requirements

  • Sensor Type The supplied technical diagram identifies the FS-354AQ-DP as using active infrared sensing for touch-free hand detection.
  • Factory Detection Distance The nominal factory sensing distance shown is approximately 25 cm (10 in), based on a standard detection target.
  • Field-Adjustable Range The detection range can be adjusted between approximately 16 and 32 cm (6.3–12.6 in) to suit the installed faucet and basin relationship.
  • Detection-Zone Clearance Keep permanent fixtures, accessories and obstructions out of the intended sensor axis and hand-position zone.
  • Reflective-Surface Check Commission the sensor with the actual basin and surrounding finishes installed, particularly where highly reflective surfaces occur within or near the sensing field.
  • Water-Supply Requirement The technical diagram identifies a G1/2 in (DN15) water-supply connection and an operating water-pressure range of 0.05–0.7 MPa.
  • Power Configuration The automatic sensor system supports DC 6V using four AA batteries or an AC 110–220V power configuration.
  • Automatic Timeout The supplied technical drawing identifies an automatic 30-second timeout to terminate continuous activation.

Project verification: The infrared sensor detection-zone diagram is a coordination and commissioning resource and should not be scaled. Before final installation, verify the active-infrared sensor orientation, 16–32 cm adjustable detection range, approximately 25 cm factory set point, faucet and basin centerline relationship, intended hand-activation area, water-stream landing zone, potential reflective surfaces, nearby accessories and obstructions, G1/2 / DN15 supply connection, 0.05–0.7 MPa water pressure, selected power arrangement and automatic timeout against the approved project requirements. Final detection performance should be tested after all countertop, basin and surrounding finish work is complete.
