Microwave with Photocell
Onlysuitablyqualifiedpersonnelshouldinstallthisequipment.
The K4025 is a high-performance, communicating presence detector. The
K4025 is equipped with a regulating photocell to control digital DSI ballasts
(whenusing theK4025’s Digital Output) and a volt-free output for control of non-
dimmable lighting loads. The K4025 incorporates OneSwitch Dimming, local
manual operationofanycontrolledlightingload.

Location
TheK4025is an extremelysensitivemovementdetector;itis essentialtherefore
that it be installed on a rigid surface that will not itself be subject to movement or
vibration.
Please note that K4025 is not recommended for applications where there are
large surface areas of metal, e.g. metal ceiling or floor tiles, as unpredictable
sensitivitymayresult.
The units are graded according to four variations in operating frequency. Each
typecanbeidentified bydifferentcolour-codingonthedetectorlabelandcarton.
For reliable operation it is essential that units of the same colour code do not
occupyadjacentpositionsinopen-planareas(seeexamplebelow).

K4025 is designed to control up to25 DSI luminaires, aswitched load of up to6
Ampsora combinationofthetwo.TheDSIinputterminalsontheballastsshould
be connected in parallel with each other and to the Polarity-Free Digital Output
terminals on the rear of the K4025. Each DSI luminaire is controlled completely
byitsdigitalinputandthereforewouldnormallyhaveapermanentpowersupply.
Turningthepowerofftosome lightswithinacontrolcircuitwillnothaveaffectthe
operation of those lights that remain powered up and under the control of the
K4025.
When switching via the volt-free output multiple K4025s may be connected in
parallel provided the controlled load does not exceed 6Amps. If digital ballasts
are also being controlled the digital outputs from each detector must not be
mixedeveniftheyareofthesametype.
OneSwitch Dimming affords local control to the end-user whereby a simple,
momentary, push-to-make wallswitch can be used to raise orlower the lighting
level or toggle the output of the unit ON or OFF. A short press (less than
1second)togglesalloutputsfrom OFFto ONorfrom ONto
OFF.A long press will ramp the digital outputeither up or down with no effect on
the volt-free output. If the output prior to pressing the switch is above 90% the
output will ramp down; if below 90% it will ramp up. If the latest press and the
current press are within 5 seconds of each other it will ramp in the opposite
direction. Alatching switch can be used to override the outputs OFF or ON at
maximumoutput.

Commissioning
Sensitivity to Movement
Factory Default Settings
The units are supplied with the factory default settings shown below which
render commissioning unnecessary in many applications. To make use of the
programmable settings, an infrared commissioning tool is required
(K4053/K4050).A ten-second time delay is selectable from either programmer
toaidcommissioning.
While the factory settings will be correct for many applications, the sensitivity
can be adjusted if required. There are four basic levels of sensitivity (MAX,
HIGH, MED and LOW) - called the ON RANGE. When the lights go off, the
sensitivity can be programmed to reduce to a proportion of the ON RANGE in
order to make the unit more resistant to unwanted triggering due to peripheral
activity. The optionsare 100% (no change in sensitivity), 75%or 50%. Like all
programmable parameters, the sensitivity setting willbe retained in the event of
apowerfailureandcanbere-programmedanynumberoftimes.
These are the settings to which the units have been programmed before
they leave the factory.
Setting the Photocell
The regulating light level is set using either a hand-held controller (K4052 or
K4051)orviatheinfraredprogrammerK4053/K4050.
Using a light meter, set the required light level and choose Set Light Level in the
USERREMOTEmenuon theK4053(orpresstheSTOREbuttonontheK4050.
Asnapshot of the current conditions is taken by the detector and stored as the
regulating set point. When used with regulating ballasts, the photocell may hold
lights off upon entry should sufficient natural light be available. It will only turn
lightsoffinanoccupiedareaifBright-Outissettoyes.
UsePassivemodeinapplicationswherelightlevelregulationisnotrequired(eg,
when controlling non-dimmable ballasts) but it is desirable to hold off the
controlledlightingwhennaturallightissufficient.
The parameter ‘Threshold’ on the K4053 menu is designed to programme the
K4025’s passive photocell set point, which determines whether the lights will be
allowed to turn on as an unoccupied area is entered. The threshold is
programmedasanumberbetween1(darkest)and254 (brightest).Thisnumber
is not scaled to correlate with ‘lux’ measurements made using a light meter, but
neverthelessisatruerepresentationofthelightlevelperceivedbytheK4025.
Inordertoassistwithselectionoftheappropriatethresholdsetting,thelightlevel
currently perceived by the detector (in terms of a number between 1 and 254)
can be viewed on the K4053 screen briefly following a download operation. The
number represents the light level immediately before the download took place.
When setting the regulating level as described in the previous section the
threshold is also set to the current measured level. The K4025 will ensure that
lights remain on whilst an area is occupied regardless of ambient lighting
conditions. However, when controlling a regulating load and with Bright Out set
to YES, if the ambient level increases sufficiently, then the regulating load will
turnoff.

ii) SwitchingPhotocellOnly(PASSIVE=YES)
Note:
Tip: Turn the lights off first (using user-remote found in utilities) if you want to
measure the perceived light level with no contribution from the controlled
lighting.

User Overrides
The end-user can configure a number of lighting scenes that can be recalled
using a hand-held override. With a K4052 hand-held controller lighting can be
overridden OFFor ON, or a set level can be chosen. Regulating and switched
loads can be adjusted independently through a combination of OneSwitch
DimmingandtheK4052.

2. Ameansfordisconnectionmustbeincorporated in thefixed wiringin accordancewiththecurrent

4. Thedimmingcontroloutputshouldbeconnectedonlytothecontrolinputoftheballasts-neverto

5. Due to the fact that the photocell is on the ceiling looking down, it is not possible for
measurements made with a lux meter on the working plane to remain constant when daylight

6. 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
manufacturerof the luminaires to ensure that they are compatible with automaticcontrols in this
respect.
7. The detectors are extremely sensitive to movement; they must be mounted on a solid surface
