DETECTION AND ACTIVATION
- When the sensor detects a user, a slow-flashing
red light appears in the sensor window.
- After 1-2 seconds of detection, the light flashes
rapidly, the sensor immediately activates the
solenoid valve, beginning water flow.
- The valve remains open while the user is detected.
- The valve closes when the user is no longer detected.
- The sensor is set to activate the solenoid valve for a
maximum of 30 seconds before automatically
shutting off.
Note:
Sensor range is factory preset to 20";
Optional range adjustment remote available
to adjust range from 1" min. to 30" max.
(SEE FIG. 2)
