```

```

5.1 General Performance Requirements

Provide commercial touchless faucet systems engineered for reliable activation, controlled water delivery, automatic shutoff, serviceable operation, and stable performance within the published hydraulic, electrical, and environmental limits of the selected model.

Performance shall be evaluated as a complete system consisting of the faucet body, sensor, controller, solenoid, power source, flow-control device, supply arrangement, and related accessories.

Individual component ratings shall not be used to represent complete-system performance unless compatibility and assembled-system operation have been verified.

5.2 Minimum Performance Schedule

5.3 Hydraulic Performance

Faucet assemblies shall provide controlled discharge within the published operating-pressure range without leakage, uncontrolled flow, unacceptable pulsation, excessive splash, or unstable stream formation.

Hydraulic performance shall be coordinated with the selected outlet device, lavatory geometry, supply pressure, water temperature, mixing arrangement, and system demand.

5.4 Rated Flow Performance

Provide the flow rate shown in the approved fixture schedule and product submittal.

Flow shall be controlled by a factory-supplied or manufacturer-approved aerator, laminar outlet, spray outlet, or pressure-compensating device.

Field modification of the rated outlet device is not permitted unless approved in writing and verified against applicable water-use, certification, splash-control, and performance requirements.

5.5 Pressure Performance

Faucet systems shall function within the model-specific published operating-pressure range. Unless otherwise documented, use 10 to 100 psi as the project design range.

Maximum static pressure at the faucet connection shall not exceed the published product limit or the maximum permitted by the plumbing design.

Where pressure exceeds the product limit, provide pressure regulation upstream. Where pressure is insufficient, correct the system condition before commissioning the faucet.

5.6 Pressure-Compensating Performance

Where pressure-compensating flow control is specified, provide an outlet device designed to limit excessive flow variation across the published operating-pressure range.

Pressure compensation shall not be represented as eliminating the need for proper system pressure control, adequate pipe sizing, or hydraulic balancing.

5.7 Sensor Activation Performance

Sensors shall detect normal hand presence within the intended hand-washing zone and initiate water flow without requiring contact with the faucet.

Under approved installation conditions, activation response should occur within 100 to 300 milliseconds, with a specified maximum response time of less than 300 milliseconds where supported by the selected model.

5.8 Detection Range

Detection range shall be factory-set, self-calibrating, or field-adjustable according to the selected model.

Where adjustable sensing is provided, the available range may extend from approximately 1.2 to 10 inches.

Final adjustment shall place the sensing zone within the basin and normal hand-washing area without extending unnecessarily toward the backsplash, drain, adjacent fixture, room circulation path, or reflective surface.

5.9 Detection Stability

Sensor performance shall remain stable under anticipated restroom conditions, subject to the limitations of the selected sensing technology.

Where highly reflective materials, direct sunlight, mirrored surfaces, black fixtures, unusually deep basins, or closely spaced electronic products are present, verify suitability through model-specific review or mockup testing.

5.10 Anti-Ghost Activation

The sensing system shall be configured to reduce unintended activation caused by stationary objects, basin reflections, drain movement, cleaning equipment, or adjacent-user activity.

Anti-ghost performance depends on correct faucet placement, sensor alignment, basin selection, adjustment, and environmental coordination and shall not be treated as independent of installation conditions.

5.11 Automatic Shutoff Performance

Water flow shall stop automatically when the user’s hands leave the intended sensing zone.

The control system shall include a maximum-run safety shutoff where supported by the selected model.

After a safety time-out event, normal operation shall resume according to the product’s programmed reset sequence.

5.12 Continuous-Flow Protection

The faucet shall be designed so that loss of normal sensor input does not intentionally command uncontrolled continuous water flow.

A normally closed solenoid is preferred where compatible with the selected product architecture and project requirements.

5.13 Solenoid Performance

The solenoid shall open and close in response to valid controller commands and remain compatible with the specified voltage, pressure, temperature, and flow range.

5.14 Battery Performance

Battery-powered models shall use the manufacturer-specified battery voltage, chemistry, pack, or holder.

Where documented for the selected model, battery endurance shall be approximately 300,000 to 500,000 activations under stated laboratory or estimated-use conditions.

Actual battery service life may vary according to traffic, activation duration, sensor adjustment, battery quality, temperature, maintenance, and standby power demand.

5.15 Low-Battery Performance

Where supported by the selected model, provide visual, diagnostic, reduced-operation, or other low-battery indication before complete loss of normal service.

The project maintenance plan shall not rely solely on low-battery indication; battery replacement intervals shall be based on documented facility usage and inspection.

5.16 AC and Hybrid Power Performance

Hardwired and hybrid-powered units shall operate from the manufacturer-specified low-voltage transformer, power supply, or central power system.

AC/DC hybrid models shall transfer to backup power according to the selected system design without requiring manual reopening of the water supply.

Power interruption, restoration, and backup behavior shall be verified during commissioning where critical to facility operation.

5.17 Electrical Performance

• Operate at the voltage identified in the approved product submittal.
• Use manufacturer-approved transformers, power modules, wiring, and connectors.
• Protect connectors from accidental separation and moisture exposure.
• Avoid exposed energized conductors within accessible service areas.
• Coordinate power demand where multiple faucets share a central supply.
• Provide accessible isolation or disconnect means where required by the electrical design.

5.18 Temperature Performance

Components exposed to water shall remain suitable for the published operating-temperature range of the selected model.

Where documented, specified component temperature capability may extend from 39 to 176 degrees F.

This temperature range does not establish the permitted hand-washing delivery temperature. Final outlet temperature shall comply with the plumbing design, project criteria, code requirements, and approved temperature-control system.

5.19 Environmental Resistance

Electronic components and enclosures shall be suitable for the anticipated restroom environment and installed location.

5.20 Ingress Protection Limitations

An ingress-protection rating applies only to the rated component, enclosure, and test condition identified by the manufacturer.

An IP rating shall not be interpreted as permission to submerge components, pressure-wash control boxes, expose connectors to standing water, or disregard installation instructions.

5.21 Finish Durability

Visible finishes shall withstand normal handling, approved cleaning, and commercial restroom use without premature peeling, blistering, cracking, or unacceptable discoloration.

Where corrosion or salt-spray testing is documented, submit the test method, exposure period, substrate, coating type, and acceptance criteria.

Testing of a finish sample or representative component shall not be represented as proving identical performance for every finish, substrate, geometry, or manufacturing process.

5.22 Mechanical Durability

Faucet bodies, mounting assemblies, outlets, sensor windows, and exposed components shall withstand normal commercial use when properly installed.

5.23 Vandal-Resistance Performance

Where vandal-resistant construction is specified, exposed components shall incorporate model-specific measures such as concealed fastening, tamper-resistant outlets, protected sensors, reinforced mounting, or restricted service access.

Vandal-resistant construction reduces ordinary tampering risk but does not make the product immune to deliberate abuse, tools, impact, or destructive force.

5.24 Water-Efficiency Performance

Water-use performance shall be based on the approved rated flow-control device and automatic shutoff sequence.

Do not calculate expected savings from rated flow alone. Project water use also depends on activation frequency, run duration, user behavior, pressure, maintenance, and false-activation control.

Where water-efficiency certification is required, submit documentation for the exact faucet and outlet configuration.

5.25 Hygiene-Oriented Performance

Touchless activation shall reduce the need for users to contact conventional faucet handles during normal operation.

Where a laminar outlet is specified for a healthcare or other controlled environment, verify that the selected outlet configuration aligns with the facility’s infection-control, maintenance, and water-management requirements.

Touchless operation does not replace cleaning, water-management planning, temperature control, flushing, maintenance, or infection-control procedures.

5.26 Noise and Water-Hammer Control

The faucet system shall operate without objectionable chatter, repeated solenoid cycling, or abnormal vibration under approved operating conditions.

The plumbing system shall provide suitable pressure control, pipe support, air chambers, water-hammer arrestors, or other measures where rapid valve closure may create unacceptable hydraulic shock.

Faucet replacement alone shall not be assumed to correct building-system water hammer.

5.27 Serviceability Performance

The installed system shall allow common service procedures without destructive access or removal of unrelated fixtures.

5.28 Reliability Verification

Where project-specific reliability documentation is requested, provide available model-specific test summaries, cycle data, quality-control records, or manufacturer declarations.

• Sensor activation testing.
• Solenoid cycle testing.
• Leak or pressure testing.
• Power-consumption or battery-life evaluation.

• Within approved thickness limits.
• Provided with correctly sized mounting openings.
• Free from cracks, chips, delamination, and unsupported edges.
• Accessible below the mounting location.
• Compatible with required gaskets and support hardware.

7.14.4 Deck Thickness Verification

Measure total deck thickness at the faucet opening, including surface material, substrate, reinforcement, build-up, liners, and attached backing.

Confirm the measured thickness permits full engagement of the approved mounting shank, washer, support plate, and mounting nut.

7.14.5 Mounting-Shank Engagement

Verify sufficient threaded shank remains below the deck for complete and secure engagement of required mounting hardware.

Do not omit washers, support plates, or reinforcement to obtain additional thread engagement.

7.14.6 Excessive Deck Thickness

Where deck thickness exceeds the approved mounting range, stop installation and obtain an approved corrective detail.

Corrective measures may include:

Do not grind, thin, or remove structural deck material without authorization from the responsible fabricator and design authority.

7.14.7 Thin or Flexible Decks

Provide approved reinforcement where the deck may flex, deform, oil-can, or crack under normal faucet loading.

Reinforcement shall distribute mounting forces without interfering with the basin, countertop supports, hoses, wiring, or service access.

7.14.8 Hollow Deck Assemblies

Where the deck contains a hollow core, air space, cellular structure, or unsupported build-up, provide approved compression support or reinforcement.

Mounting hardware shall not crush the deck or pull surface layers together in a manner that damages the finished assembly.

7.14.9 Basin-Flange Coordination

Verify the basin flange, overflow channel, clips, anchors, adhesive, and support frame do not obstruct the faucet shank or mounting hardware.

Do not cut or modify basin flanges, overflow components, or manufacturer-installed basin supports without approval.

7.14.10 Basin-Cutout Clearance

Confirm adequate material remains between the faucet opening and basin cutout to support the faucet and resist cracking.

Report inadequate edge distance, fractures, weak seams, or unsupported material before mounting.

7.14.11 Opening Verification

Confirm the mounting opening is correctly sized, round or shaped as required, clean, smooth, and free from sharp edges.

7.14.12 Opening Edge Protection

Provide grommets, sleeves, bushings, or smooth edge treatment where hoses or wiring pass through openings that may cause abrasion.
