Fontana Freestanding Brushed Nickel Finish Commercial Automatic Sensor Faucet
25 cm Infrared Calibration, 0.5-Second Response & 60-Second Safety Cutoff Engineering
Engineered for commercial washrooms, this solid-brass sensor faucet combines automatic infrared control, 6V battery operation, and built-in filtration for reliable touch-free performance.
How does the factory-set 25 cm sensing distance affect basin coordination?
The sensor is factory configured for an approximately 25 cm detection zone. During commissioning, installers should verify that the completed basin does not continuously reflect infrared energy into the receiver while ensuring normal hand positions remain reliably detectable throughout the intended washing area.
What is the engineering significance of the 0.5-second activation delay?
The specified 0.5-second delay provides a controlled interval between valid infrared detection and valve response. This helps prevent extremely brief disturbances from initiating unnecessary flow while maintaining sufficiently rapid activation for repetitive handwashing cycles in high-traffic commercial environments.
How does the 0.05–0.6 MPa operational pressure range influence plumbing design?
The operating range corresponds to approximately 7.3–87 PSI. Dynamic pressure should be checked at the DN15 (G1/2-inch) connection during representative simultaneous demand because branch-line friction, filters, and isolation valves can reduce pressure available to the automatic valve.
How does the 60-second automatic cutoff protect against abnormal continuous activation?
If the sensor remains continuously activated, electrical power automatically cuts off after approximately 60 seconds. This limits unattended water discharge caused by prolonged obstruction or abnormal detection while providing an additional water-control safeguard for high-use public and commercial installations.
