1.0 IntroductionThe Clipsal 752/225CUI automatic sensing device is a dual technology motion detector.

The significant feature of the 752/225CUI is that it uses both ultrasonic and passive infrared (PIR) technologies to perform the ultimate task of sensing, employing a programmable DIP switch for the actual environmental conditions.

This means that combinations of both ultrasonic and infrared can be programmed to suit the actual conditions of the environment resulting in ultimate performance.

2.0 How it Works

2.1 Ultrasonic DetectionThe 752/225CUI consists of a transmitter and a receiver transducer to provide total volumetric sensing with no blind spots.

2.2 Passive Infrared DetectionThe 752/225CUI consists of four PIR detectors which are specially aimed to all four corners of the room to ensure the farthest distances of the room are covered. The 752/225CUI can detect an area up to 15m x 15m (225m2).

The sensor operates on 24V d.c. and is designed to work with the 752PR power pack and relay switching module (supplied).

When someone enters a room in which the sensor controls the lighting, the lights are turned on automatically. The signal derived activates an adjustable timer (30 seconds to 30 minutes), which in turn activates an electrical relay in the power pack, turning the lights on.

If no movement or presence is detected for the time selected, the relay de-energises, turning the lights off.

The 752PR device has a C-Bus auxiliary unit connection terminal which is to be connected only to a C-Bus L5504AUX or C-Bus bus coupler unit.

5.0 Detection Pattern

Detection patterns are based on 3m ceilings and tiled floors. In large carpeted areas, a higher sensitivity for ultrasonic may be required to overcome the absorption of the ultrasonic waves by the carpet.

6.0 Eliminating Unwanted Detection




7.0 Mounting Procedure1. Fit power supply in ceiling space within 1m of sensor position. (Fit surface mount

socket or similar for supply from lighting circuit.)

a. Fix base of power supply to beam.

b. Fix PCB to base using screws provided.

c. Fit 752LD (1m lead) to connector on PCB at extra low voltage end.

d. Fit load cables to terminals on PCB, stripped to length as shown.

e. Cut out cover as required to suit load cables.

f. Screw cover to base.

2. Fit sensor to ceiling in (a predetermined) position.

a. Fix mounting flange to ceiling.

8.0 Wiring Diagram

WarningIt is recommended that this product should be hard wired as per the wiring diagram.

When connecting multiple 752PR modules to control the same load, 3 pin plugs or similar must not be used, as this can result in the plugtop pins becoming ‘live’ under certain conditions.

For safety reasons, it is recommended to always shut down power to all relevant circuits before undertaking any installation or maintenance of this product.

9.0 CommissioningOnce power has been installed, determine which program selection schedule best suits the application.

Program Selections Schedule

#1 PROGRAM SELECTION is used in common office areas. Multi-sensor application using this program selection will enhance the detection that is needed in partitioned office areas.

Note: This program uses only ultrasonic detection.

#2 PROGRAM SELECTION is used in areas in which turbulence, such as air draft or high air flow, is a problem.

Note: a) This program uses only passive infrared detection.

b) If environmental conditions are too severe for this program selection, use program selection #5 instead.

#3 PROGRAM SELECTION is used in areas in which high sensitivity is needed and no turbulence or adverse environmental conditions exist.

Note: This program selection permits maximum sensitivity for dual sensor technology.

#4 PROGRAM SELECTION is used in rooms and areas that demand high sensitivity once the room has been occupied, but cannot be falsely triggered by the high turbulence, (hanging mobiles, etc.) such as in classrooms.

Note: Sensitivity increases after lights are switched on.

#5 PROGRAM SELECTION is used in areas where turbulent conditions exist in which no other program selection can satisfy.

Note: This program selection requires both ultrasonic and passive infrared detection simultaneously to occur in order to trigger the timing circuit that will ultimately keep the lights on.

9.1 Time Delay TableSet the timer delay to suit, as per the table below:

Example of timer settings in minutes

Stock Room = #15Hallway = #10Restroom = # 7Office = # 8Classroom = # 9

Note: For areas larger than 10m2, set timer adjustment to #5 and perform walk testing using the actual light fixtures. After the walk testing is completed, set timer adjustment to #15.

Note: When logic key or paper clip is inserted into the slot, lights will always be on. There is no shock hazard present when using a logic key or a paper clip.

This bypass function is for emergency use only.

9.2 Approximate Sensitivity AdjustmentSet sensitivity adjustment to suit as per size of the room, shown below:

12.0 Troubleshooting

Problem The power is restored. Both the red and green LEDs do not blink when making motion.

Solution A Adjust sensitivity and set level to a higher setting as required by observing red and green LEDs.

Solution B Remove sensor and measure if 24V d.c. is present between red and black leads. If no voltage is present, check power connection and power/switch pack. If voltage is present, replace sensor with new one and send defective sensor to Clipsal Australia Pty Ltd.

Problem Lights are on continuously and do not shut off when no one is present.

Solution Re-check all your connections then disconnect sensor while power is still on. If lights remain on, this indicates that there is a short in the 752LD Lead connecting the sensor and the power/switch module. Solution to this problem is to replace the 752LD Lead. Check also for external causes such as excessive turbulence (hanging mobiles, etc). Refer to Program Selection schedule on page 8 for detector options.

Problem Lights will not switch on even after sensor is disconnected and red and blue wires are shorted.

Solution This could indicate a broken wire in the 752LD Lead. Next, disconnect the 752LD Lead at the power/switch module and short the pins where the red and blue wires connect. If lights still do not switch on, replace power/switch module after checking if all connections were made correctly.

Problem LED blinks but lights will not switch on.

Solution Check if sensor is working when bypassing all electronics. This can be done by inserting the key provided with each unit. If lights switch on, replace defective sensor.

Problem After all connections are verified, lights stay on when no one is present, and from time to time LED blinks.

Solution A Red LED blinks. Check for hot air turbulence and mask lens for PIR detection in accordance with figure on page 6 (6.0).

Solution B Green LED blinks (ultrasonic). Turn sensitivity adjustment to a lower setting and/or physically rotate sensor by 90o. (Refer to page 8).
