Fontana’s sensor-operated flushing systems are classified as spec-grade because they are engineered for continuous operation in high-traffic commercial environments such as airports, hospitals, and office complexes. These systems utilize solid brass valve bodies, high-cycle solenoids, and pressure-compensating diaphragm assemblies to ensure consistent performance across a wide range of water pressures. Unlike light-duty systems, they are designed to withstand hundreds of thousands of flush cycles without performance degradation. Additionally, they comply with key industry standards such as ASSE 1037 and ADA requirements, ensuring reliability, safety, and accessibility in demanding installations.

The infrared sensing system in Fontana flush valves operates by emitting continuous IR signals and measuring their reflection from nearby objects. When a user enters the detection range, the reflected signal is processed by a microcontroller that confirms presence based on signal strength and duration. Once the user leaves the area, the system initiates a controlled delay before triggering the flush, preventing premature activation. Advanced filtering algorithms are used to ignore transient reflections from moving objects or changes in ambient lighting, ensuring accurate detection and minimizing false flush events even in high-traffic or variable lighting environments.

The solenoid valve acts as the critical interface between the electronic sensor system and the mechanical flushing mechanism. When the sensor detects that a user has exited the fixture area, it sends a signal to energize the solenoid coil, which generates a magnetic field that lifts an internal plunger. This action allows water pressure to act on the diaphragm assembly, initiating the flush cycle. The solenoid is designed for rapid response, low power consumption, and long operational life, making it suitable for continuous use in commercial restroom environments where reliability is essential.

The diaphragm mechanism regulates water flow by maintaining a controlled pressure differential between two chambers inside the valve. When activated, the diaphragm lifts due to pressure imbalance, allowing water to flow into the fixture. The system includes calibrated bypass orifices that control how quickly pressure equalizes, which determines the duration and volume of the flush. This design ensures that flush performance remains consistent regardless of fluctuations in supply pressure, providing reliable operation in buildings where water pressure may vary throughout the day.

Fontana systems are available in battery-powered, hardwired, and hybrid configurations, each designed to suit different installation requirements. Battery-powered units are ideal for retrofit projects because they eliminate the need for electrical wiring and offer long battery life, often lasting several years depending on usage. Hardwired systems provide continuous power from the building’s electrical supply, making them suitable for high-traffic environments where uninterrupted operation is critical. Hybrid systems combine both approaches by including battery backup, ensuring the system continues to function during power outages and enhancing overall reliability.

Fontana sensor-operated flush systems are designed to optimize water usage through precise control of flush volume and duration. By using calibrated diaphragm assemblies and electronic timing controls, the systems deliver only the necessary amount of water per flush, significantly reducing waste. Many models support low-flow configurations and optional dual-flush functionality, which further enhances efficiency. These features help facilities meet EPA WaterSense standards and contribute to LEED certification by reducing overall water consumption without compromising performance.

Yes, advanced Fontana systems can be integrated into building management systems (BMS) and smart facility platforms, allowing for centralized monitoring and control. These integrations enable the collection of operational data such as flush counts, usage patterns, battery status, and system diagnostics. Facility managers can use this data to implement predictive maintenance strategies, optimize restroom usage, and reduce operational costs. This level of connectivity transforms the flushing system into an intelligent component of a larger smart building infrastructure.

Sensor-operated flushing systems significantly enhance hygiene by eliminating the need for users to physically touch flush handles, thereby reducing the spread of germs and cross-contamination. Fontana systems also support programmable automatic flush cycles that prevent water stagnation in pipes, which can reduce the risk of bacterial growth. These features are particularly important in healthcare facilities, laboratories, and other environments where maintaining high sanitation standards is critical.

Installation of Fontana sensor-operated flush systems requires proper alignment with both plumbing and electrical specifications. The systems are designed to operate within standard commercial water pressure ranges, typically between 20 and 125 PSI, and must be connected to appropriately sized supply lines. Battery-powered units require minimal electrical setup, while hardwired systems must be connected to a low-voltage power source with proper waterproofing. Additionally, sensor placement must comply with ADA accessibility guidelines to ensure usability for all individuals.

Although the initial investment in spec-grade sensor-operated systems may be higher than traditional manual flush valves, the long-term benefits include reduced water consumption, lower maintenance costs, and extended component lifespan. The modular design of Fontana systems allows for quick replacement of parts such as solenoids and diaphragms, minimizing downtime and labor costs. In high-traffic facilities, these efficiencies can result in a return on investment within a relatively short period, making the system a cost-effective solution over its lifecycle.
