8.Catch(Design shade for function adjustment, folding)

 

9.Twilight setting 2 - 2000 lux

 

10.Time setting 10 sec. - 30 min.

  

 

The desired duration of illumination of the connected light can be continuously adjusted from approx.

 

10 sec. to max. 30 min. Adjusting screw left stop position means: shortest time approx. 10 sec. (factory setting)

 

Adjusting screw right stop position means: longest time approx. 30 min.

 

The timer is restarted by any motion detected before this time elapses.

 

 

 

(1) 10 second fixed time-out used for performing a walk-test.

 

(2) 2 minute time-out

 

(3) 15 minute time-out

 

(4) 30 minute time-out

 

The “time-out” is factory preset to two (2) minutes.

 

 

 

The Sensor Switch basically operates in sensor mode. The light is switched ON To the preset time in response to movement within the detection zone

 

 

 

NOTE: The Motion Indicator LED will blink every 2 seconds while motion is detected.

 

 

If the lights are OFF, the lights will turn ON when the button is pressed, and remain ON in the presence of occupation. In the absence of motion/sound, the Sensor Unit will time-out and turn the lights OFF. If the lights are ON, the lights will turn OFF when the button is pressed. The lights will stay OFF regardless of motion detected, until the time-out expires. After the time-out expires, the lights will turn ON with the next detected motion. This is useful for slide or film presentations.

 

Manual on/auto off mode

 

 

 

In this mode the lights need to be manually turned ON by the push-button, and will turn OFF with the absence of occupation. If Manual-On mode is desired, keep the Light knob in the fully counter-clockwise (CCW) position. In this mode, the unit will not turn lights ON automatically when motion is detected. Lights can only be turned ON by manually pressing the push-button. The lights will remain ON as long as the unit detects occupancy in the sensor zone. The SK903A will shut lights OFF automatically after the space becomes unoccupied and the OFF delay time has expired. Lights can also be turned OFF manually at any time by pressing the push-button. This mode is ideal for areas where manual ON switching is required but automatic OFF switching is desired for energy savings.

 

 

 

 

 

Press and hold button 3 seconds until the LED flashes rapidly, Release button. The Sound sensor is inhibited from working but the PIR sensor continues to operate. This mode is ideal for areas where there are high ambient sound levels, such as outside near busy roads and busy shopping centres. To re-engage the microphonics system: Press and hold the button until the led flashes, sound detection is again in operation.

 

NOTE: Sensor must detect motion using Passive Infrared (PIR) FIRSTLY and then microphonics( sound sensor) will engage to hear sounds that indicate continued occupancy. If PIR does not sense, sound alone will not operate the switch.
