Fontana touchless faucets are designed to accommodate both AC (alternating current) and DC (direct current) power sources, offering versatility and flexibility in installation options. AC-powered faucets are ideal for locations with readily available electrical outlets, providing continuous and reliable power without the need for battery replacements. On the other hand, DC-powered faucets operate using batteries, making them suitable for areas where wiring for AC power may be challenging or costly.
Choosing the Right Power Source for Touchless Faucets
Power configuration is more than “battery vs hardwired.” It directly impacts sensor accuracy, shutoff timing, and
long-term water conservation. In high-traffic restrooms, stable voltage improves response consistency, reduces
nuisance activations, and helps prevent extended run times that waste water.
Battery Powered Touchless Faucets
Battery-powered sensor faucets are ideal for retrofit projects and areas with limited electrical access. They
reduce installation complexity, but should be specified with a maintenance plan (battery replacement interval,
low-battery warning, and service access) to avoid weak-voltage behavior that can reduce conservation performance.
Hardwired / Transformer Powered Touchless Faucets
Hardwired power is the standard for continuous-use spaces (airports, schools, hospitals, corporate HQs). Stable
power supports faster solenoid response and more predictable shutoff behavior, which improves both user experience
and long-term water savings.
Hybrid (Hardwired + Battery Backup)
Hybrid systems combine the stability of hardwired power with backup resiliency. They reduce disruption during
outages and allow facilities to maintain touch-free operation even when maintenance cycles slip.

FAQ Technicals: Power for Sensor Faucets
Which is better for high-traffic restrooms: battery or hardwired?
For high-traffic restrooms, hardwired power is usually preferred because it provides stable voltage that keeps
sensor response and solenoid timing consistent. This helps prevent delayed shutoff and nuisance activation, both
of which can increase water waste in continuous-use environments.
Do batteries affect water conservation over time?
Yes. As batteries decline, some faucets can experience slower valve actuation or inconsistent sensing, which can
lengthen run times or increase repeated activation cycles. Specifying low-battery indicators and a defined
replacement schedule protects performance.
When should I specify a hybrid configuration?
Hybrid is ideal when uptime is critical and maintenance resources are constrained. It reduces operational risk
during outages and helps maintain contact-free operation without performance drift.

Power Source: Battery, Hardwired, or Hybrid?
Power configuration determines stability, uptime, and conservation precision. Use this page to select the right
approach for your environment and to avoid weak-voltage issues that can cause delayed shutoff and water waste.
Best for retrofit zones and fast installs. Specify a replacement plan and low-battery alert for reliability.
Hardwired / Transformer
Best for airports, schools, hospitals, and corporate sites. Stable voltage supports consistent shutoff timing.
Hybrid + Backup
Best for mission-critical uptime. Reduces outages and maintenance risk while keeping performance consistent.
Specifier Coordination Checklist
Confirm power availability at each lavatory bank (cabinet, wall chase, or above-ceiling routing).
Define service access for transformers and control modules (no “buried” boxes).
Group fixtures per circuit for faster troubleshooting and fewer downtime events.
Commission shutoff delay for conservation (avoid long run-on) without nuisance cycling.
If battery or hybrid: set the replacement interval based on traffic level and planned PM schedules.
Power Source Requirements for Touchless Faucet Families
Compare battery, hardwired, and hybrid configurations. Choose the best power setup for your project’s traffic level, service access, and conservation goals.
Sensor Technology (Power Impact)
Stable power improves detection accuracy and reduces false triggers caused by weak voltage and noisy lines.
Transformer placement, access panels, and battery swap intervals should be specified—not left to chance.
In BIM coordination, power is not “a note.” It’s a modelable requirement that impacts rough-in scope, service access, and long-term performance. Use this spec-style guidance to coordinate battery, transformer, and hybrid power configurations during design development and submittals.
Model + Schedule Parameters (Recommended)
Power_Source: Battery / Hardwired / Hybrid
Voltage: (e.g., low-voltage transformer) / N/A for battery
Maintenance_Interval: battery cycle or inspection cycle
Coordination Notes (Put in Specs + Drawings)
Provide service access to transformer/control module without removing countertops.
Group fixtures by circuit to limit downtime and simplify troubleshooting.
Commission shutoff delay for conservation; verify sensor stability under final lighting.
Where battery is used, include low-battery alert + planned replacement interval.
Sample Spec Language
1. Power configuration shall be selected per fixture group based on traffic level and service access.
2. Hardwired or hybrid power shall be used for continuous-use lavatory banks unless retrofit constraints apply.
3. Provide accessible transformer/control module locations for maintenance without demolition.
4. Battery-powered fixtures shall include low-battery indication and a defined replacement interval.
5. Commission sensor activation + shutoff timing under final lighting conditions to prevent nuisance activation and water waste.
These faucets automatically switch to battery power during power interruptions, maintaining operation without interruption until power is restored. Fontana also offers hybrid options that allow users to switch between AC and DC power as needed, adding convenience and adaptability to installations. Regardless of the power source, Fontana touchless faucets are engineered for energy efficiency, incorporating features like automatic shut-off timers and low-power modes to conserve electricity. Battery backup options ensure uninterrupted operation during power outages, further enhancing reliability. This comprehensive approach to power sources ensures that Fontana touchless faucets deliver consistent performance, convenience, and sustainability in a range of settings.
