Fontana DSFD0024GS Vessel Sink and Chrome Touchless Sensor Faucet: Sensor Detection Zone Drawing

This sensor-detection resource is intended to support architects, plumbing engineers, contractors, installers and facility personnel coordinating the Fontana DSFD0024GS vessel sink and chrome touchless sensor faucet combination. The drawing package communicates the touchless sensing zone, recommended hand position, infrared sensor axis, activation band, no-drip release area, water-delivery path, basin alignment and automatic shutoff sequence required for reliable hands-free operation.

Fontana DSFD0024GS Touchless Sensor Operating Zone

The DSFD0024GS uses an infrared motion sensor positioned beneath the chrome spout near the water outlet. The sensing field projects downward toward the intended hand position so the faucet can activate without physical contact. Proper alignment between the faucet, sensing field and vessel basin helps maintain reliable operation and controlled water delivery.

  • Model: DSFD0024GS

Required Sensor Detection & Activation Drawing Package

Each sensor coordination drawing should use a consistent faucet centerline, basin centerline and sensing-axis reference. The package should clearly identify the infrared sensor location, activation zone, recommended hand position, no-drip release area, water-delivery path, detection range and automatic shutoff sequence before final installation and commissioning.

Sensor Detection Zone Drawing

Provides the complete operating relationship between the touchless sensor, hand target area, water stream, vessel basin and automatic shutoff sequence.

Side Elevation — Sensor Activation Zone

Shows the infrared sensing field beneath the spout, the recommended hand position and the typical 60–100 mm (2.4–3.9 in.) detection range.

Sensor Location

Identifies the infrared / motion sensor on the underside of the spout near the water outlet, positioned to monitor the user's hand below the faucet.

Sensor Axis

Defines the central detection line projecting downward from the sensor and provides the primary reference for coordinating the hand-use area.

Recommended Hand Position

Shows the user's hand positioned beneath the water outlet and within the sensing field for comfortable, hygienic and reliable hands-free activation.

Activation Zone

Identifies the sensing envelope where hand presence triggers the faucet control system and initiates water flow.

No-Drip Release Zone

Shows the lower release area beneath the spout intended to reduce unintended reactivation and dripping as the user's hand leaves the sensing field.

Plan View — Sensor Coverage Alignment

Shows the faucet centerline, basin centerline, sensor coverage area and hand-target zone aligned over the usable vessel-basin wash area.

Automatic Shutoff Sequence

Summarizes the operating sequence as hand enters zone → sensor detects → water turns on → hand removed → flow stops, with a 30-second adjustable maximum shutoff reference.

Engineering note: The detection range, activation area, sensor axis, hand position and automatic shutoff behavior shown are nominal coordination references. Final sensing performance should be verified on site because environmental conditions, reflective surfaces, basin geometry, faucet mounting position, power configuration and control settings may affect operation.

Sensor, Basin and User Coordination Considerations

Sensor Alignment

Keep the infrared sensing field centered beneath the spout and oriented toward the normal hand-use area above the vessel basin.

Hand Target Zone

Position the faucet so users can place their hands naturally within the sensing field without touching the spout or reaching awkwardly over the vessel rim.

Water-Stream Alignment

Coordinate the sensor zone and outlet so water reaches the user's hands while remaining fully inside the vessel sink.

Reflective Surface Control

Avoid highly reflective accessories, polished objects or other surfaces immediately adjacent to the sensor window that may affect detection behavior.

No-Drip Performance

Keep the lower sensing area clear so the faucet can recognize when the user's hand leaves the active field and shut off without unnecessary retriggering.

Power & Control Setup

Verify the AC or DC power source, control connections and sensor wiring before commissioning so activation and automatic shutoff operate consistently.

Sensor Operation and Commissioning Best Practices

Verify Detection Range

Test the faucet after installation and confirm that normal hand movement is detected reliably within the intended 60–100 mm operating zone.

Clean Sensor Window

Keep the sensor window free from fingerprints, soap film, mineral deposits and construction debris that could reduce detection performance.

Test Activation

Confirm water begins promptly when a user's hand enters the sensing field and remains stable during normal washing.

Test Shutoff

Remove the user's hand from the detection zone and confirm that water flow stops correctly without repeated activation.

Verify 30-Second Limit

Confirm the adjustable maximum automatic shutoff operates as intended if the sensing condition remains active for an extended period.

Final Basin Check

Verify that the sensing field and water stream both remain within the usable basin area and do not conflict with the vessel rim or nearby accessories.

Professional Engineering and Accessibility References

Project verification: Sensor detection drawings are coordination tools and do not replace approved project submittals. The architect, plumbing engineer, contractor and licensed installer should verify sensor location, detection range, hand-entry zone, faucet centerline, basin geometry, power configuration, controller setup, automatic shutoff timing, water-stream alignment and locally applicable plumbing or accessibility requirements before final installation and commissioning.
