Ultrasonic Motion Detector Installation Instructions
1.0 Introduction The Clipsal 752/225CU Motion Sensor uses ultrasonic technology to perform the ultimate task of sensing.
2.0 How it Works 2.1.Ultrasonic Detection The 752/225CU consists of a transmitter and receiver transducer to provide total volumetric sensing with no blind spots. The sensor operates on 24V d.c. and is designed to work with the 752PR power and relay switching module (supplied). When someone enters a room in which the sensor controls the lighting, the lights are turned on automatically, and in this manner the load can be controlled. 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 and load 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.

Warning It 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. 6 of 12

11.0 Troubleshooting Problem
The power is restored and the red and LED does not blink when making motion.
Solution A
Adjust sensitivity and set level to a higher setting as required by observing red LED.
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).
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
Turn sensitivity adjustment to a lower setting.
