INSTALLATION 

Ensure the power has been turned OFF at the circuit 

breaker. 
Prepare the wires with proper length (cut the excessive 

length, if necessary) and strip for connection. Connect 

the sensor wires to the wires of line voltage and load 

according to the above wiring diagram of desired control. 
Carefully bend the wires in the wall box after all wires are 

properly connected. Mount the sensor in the wall box 

with the screws provided. 
Conduct sensor operation test (refer to the TESTING 

section). Replace the wall plate cover after sensor testing 

and setting completed.

WIRING DIAGRAM

The sensor may be available with other control options, 

consult a qualified electrician or contact [email protected] 

for assistance.

NOTE: Connect the 
GREEN wire to the 
GROUND for safety.

OPERATION

The LDS-700 series dual-tech wall switch sensor employs two 

different sensing technologies (PIR & HFD) to detect the 

occupancy/vacancy status within its coverage, and controls the 

connected load as per sensor setting. A dual color LED indicates the 

status of sensor detection, BLUE is PIR and GREEN is HFD. Pressing 

the push-button will change the state of relay contacts manually. 

TIME setting determines the delay time that the sensor will 

hold the load ON after the last motion detected. Factory 

setting is 10 minutes, and it can be changed by pointing the 

arrowhead of potentiometer to the specific position.  

TIME - Delay time

LUX setting determines the threshold of ambient light level 

that the sensor will inhibit switching ON the load. The factory 

setting is ALS disabled (24 Hr) for testing convenience, and it 

can be changed by pointing the arrowhead of potentiometer 

to the specific position. 

LUX – Ambient light level 

TESTING

Restore the line power for sensor operation and wait for 

the sensor to warm-up (GREEN LED will blink during the 

warm-up period). 
Move within the desired range and observe the sensor 

detection. BLUE blink indicates the PIR sensor detected, 

and GREEN blink indicates the HFD sensor detected. 

Move outside of the desired range and observe if the HFD 

sensor can detect. If GREEN LED blinks, reducing the HFD 

sensitivity accordingly. 
Replace the wall plate cover after sensor testing and 

setting completed.

NOTE: 

The connected load will be switched ON as delay 

time set (factory default 10 minutes) after the power applied. 

The delay time can be set to the shortest (10 seconds) for 

test convenience.

 Ensure to set the TIME back to the 

desired delay for optimum operation after test. 

To program the sensor 

operation mode or change 

the settings, press the 

push-button cover and slide 

it down as shown.

Via DIP switch setting, the LDS-700 can be programmed 

to adjust the HFD sensitivity, operate as a single HFD 

wall switch sensor, control the load as an Occupancy 

Sensor or Vacancy Sensor, and set the push-button 

operation to turn ON/OFF manually or in Presentation 

Mode (PM).

Occupancy sensor switches the light 

ON automatically when PIR sensor 

detects the presence of an occupant. 

The sensor will switch the light OFF 

automatically if no occupant activity has been detected by 

either PIR or HFD sensor before the time delay elapses.

Vacancy sensor requires the user to manually press the 

push-button to turn ON the light. The sensor will switch the light 

OFF automatically if no occupant activity has been detected by 

either PIR or HFD sensor before the time delay elapses. 

NOTE: 

The sensor will automatically turn ON the light if it 

detects occupant activity within 30 seconds after time delay 

elapsed.

Pressing the push-button during 

occupied state will turn OFF the load 

of respective pole and hold OFF until 

the push-button is pressed again.

In Presentation Mode (PM), pressing the push-button will turn 

OFF the lights immediately, and the lights will remain OFF 

even if motion is detected. Pressing the push-button again will 

turn the light ON and the sensor will operate per its settings. If 

the time delay expires and no occupant activity has been 

detected, the sensor will return to its normal operation. The 

lights will turn ON with the next motion detected.
