Note:
The K4010 is a high performance presence detector with photocell. The photocell can be programmed to hold
lights
when areas become occupied (if the daylight contribution is sufficiently high) - it will not turn lights OFF
when an area is occupied regardless of natural light levels.
The K4010 is suitable for flush mounting in a suspended ceiling tile, maximum 54mm thick and with a minimum
clearance of 125mm between the front surface of the tile and the hard ceiling behind. The K4010 should be
mounted in the centre of the group of luminaires to be controlled.
Cut a 50mm diameter (64mm if using an
K4055 flush ring or K4054 plasterboard fixing kit) circular hole in the tile, feed the flying lead and detector through
the hole and secure into position with the locking ring. Twisting the locking ring will release the detector should th is
be necessary.
Do not position within 25cm of a luminaire.
The K4010 is supplied with a flying lead which should be taken into the first luminaire on the circuit to be
controlled, from where it will pick up its 230V supply. Control of a group of luminaires is achieved by connecting all
the luminaires in the group (typically 4) in parallel with the switched live out put of the K4010.
Setting the Photocell
1.
Wait until the time of day when the ambient light level is equal to the level at which you want the photocell to
become active.
2.
Using the K4053, select ‘Set Light Level’ from the Utilities menu and press OK while pointing at the detector
to store the current light level - the lights must be on prior to starting this process.
The detector stores the perceived light level value in the Upper Threshold.
3.
If required, the Upper Threshold value can be edited manually via the K4053. Please note, these are not Lux
levels but a representation of the light levels perceived by the detector at the time of the store command.
If a K4053 is not available,
the light level may be set by pressing the Store button on an K4050 whilst pointing the programmer at the
detector.

Walk-test Mode
Walk-test mode is used to check that the range of the presence detector is appropriate for the application. The
short off-delay enables the installer to check that lights are switching on when movements are made at the edge
of the detection zone.
1. Walk Test mode can be initiated either with the K4053 or by pressing the ‘A’ button on the K4050. Note that
when using the K4050 the position of the 12 DIL switches has no effect on the preset settings in the K4010.
2. Once in Walk Test mode, move around the area that is being controlled, stopping for 10 seconds to allow the
lights to switch off, before moving and triggering the lights back on.
3. Once walk testing is completed, the K4010 will automatically return to the 20 minute time delay after a period
of approximately 5 minutes.
Important Additional Notes
1.
A means for disconnection must be incorporated in the fixed wiring in accordance with the current wiring regulations.
2.
This equipment switches lights no more frequently than would a responsible human occupant. However, manufacturers of
some lighting types (e.g. ‘2D’ luminaires) may specify a maximum number of switching cycles in order to achieve a
predicted lamp life.
Please check with the manufacturer of the luminaires to ensure that they are compatible with
automatic controls in this respect.
