Ultrasonic Sensor

The sensor has two

Detection sensitivity
can be adjusted using
the trimpot under the
ON/OFF buttons.
When only one minute is left in the time delay, the load
connected to the relay turns OFF for one second. This
provides a one minute warning before the load(s) are
turned OFF by the sensor.
No visual alert for delay expiration warning.
Unit will beep at one minute*, at 30 seconds and at 10
seconds before turning OFF load. When Walk-Through
is active, the unit beeps three times at 10 seconds
before the load goes OFF.
*If Visible Alert is also ON, the one-minute time-out
warning beep is replaced by the visible alert.
No warnings provided.
