2.0 Description
The Clipsal 753 Series 360 Degree Infrascan is a highly reliable, state-of-the-art
passive infrared (PIR) occupancy sensor. The unit utilises an advanced quad-
element sensor array allowing instantaneous detection of movement and features
a massive 14 metre detection range.
The unit also features a slimline, fully recessed mounting facility, making it one of
the world’s most sleek and unobtrusive 360°sensors available.
The unit is designed to monitor the immediate environment, and detect people
moving within its field of view. When movement is detected, the unit will activate an
electrical load, such as a light, in response to that movement.
Designed and developed in Australia, the unit offers benefits in security, energy
management, hospitality and true ‘hands-free’ switching convenience in a wide
range of applications.

4.0 How it Works
With power applied and a suitable load connected, the Infrascan can detect any
moving infrared source (for example a person) that may intrude upon its field of view.
BoththeLight-LevelandTime-Onsettingsareuseradjustablebyremovalofthe
frontsurround.Simplytwisttoremovethecoverandadjusttrimpotasrequired.
TheLight-Leveladjustmentactivatestheloaddependentontheambientlight
levelintheeldofviewofthesensor.Thisadjustmentcanbesettoallowthe
Infrascan to operate the load at any light level between full daylight and almost
complete darkness. For example, the user can ensure the load is only activated
when movement is detected at night time. During the day time, when there is
adequate natural light, the unit can be set so it does not activate the load, as it is not
necessary to do so.
TheTime-Onadjustmentvariesthetimespanthattheloadwillremainonafter
the infrared source moves out of, or stops moving within the field of view. The
loadwillautomaticallybeswitchedoffaftertheTime-Onperiodhaselapsed.Any
period between 5 seconds and approximately 20 minutes may be set by the time
adjustmentscrew.

6.0 Installation Location
An Infrascan must be positioned correctly to ensure effective operation. The field
of view is optimum when the sensor head is mounted in a vertical position at a
height of 2.4 metres and the approach path is across the face of the sensor.
Note
• DonotmounttheInfrascanclosetoobjectswhichcancreaterapidtemperature
changes, e.g. air conditioning vents, heater flues, moving water (i.e. fountains
and sprinklers). Avoid locations where condensation is likely to form on the lens.
• DonotmounttheInfrascanonanysurfacethatissubjecttomovementdueto

8.0 Mounting Procedures
Step 1
Using a hole saw or otherwise, cut a 50mm (2”) circular hole in the ceiling
(or ceiling tile). Draw cable through hole.
Step 2:
Remove terminal cover screw and terminal cover to expose terminals. Remove
cable entry tear-away(s) from the terminal cover as required, to suit incoming
cable.
Top Cable Entry
Punch out the top cable entry hole, then fit the cable clamp to the terminal cover.
Push the two halves so that it snaps together, and clip onto the terminal cover
entry hole. The cable clamp wraps around the incoming cable. Feed cable through.
Side Entry
DONOTUSESIDEENTRY.
Step 3
Strip cable. Terminate
incoming wiring on the
appropriate terminals as
marked. Refer to Section
9 Wiring Diagrams
for further information
about wiring for different
applications.
Step 4
Fit the terminal cover,
and secure using the
terminal cover screw.
Step 5
Depress the outer
ends of the spring clips
towards the centre of the
unit and push the unit
through the hole until it
rests flat on the ceiling.

14.0 Warning- Using the 753 with Special Loads
Small Loads (<40W)
The 753 product can only drive loads greater than 40W. If you wish to drive a
smaller load, the 31CAP Load Correction Device is required to be fitted in parallel
with the load. For example: when driving a single contactor, be sure to use the
31CAP.
Loads which are Sensitive to Leakage Currents
The 753 is a two-wire device. Two-wire devices draw their power through the load.
Ifthisdeviceisusedinconjunctionwithaload,whichcannotprovideenough
continuous load current in the off-state, or the load is sensitive to a high off-
state leakage current (for example: relays, contactors, various loads with built-in
electronic control, etc.) a 31CAP Load Correction Device must be connected in
parallel with the load.
Small(Non-PowerFactorCorrected)FluorescentLoads
When a 31CAP is fitted, some small non-power factor corrected fluorescent
loads may be controlled using the 753. Success varies from manufacturer to
manufacturer. Recommend testing before installation. Installation must be
compliant with local wiring rules.
