Commissioning
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 (HP2000).
A ten-second "Walk Test" time delay is selectable to aid commissioning
Factory Default Settings
These are the settings to which the units have been programmed before they
leave the factory.
Gold Series LightSpot for use with Analogue 1-10V Ballasts
Only suitably qualified personnel should install this equipment.
This high-performance presence detector forms a stand-alone lighting control
unit. It is equipped with a regulating photocell to control analogue 1-10V
ballasts (when using the detector’s Dimming Output) and a volt-free output to
fully extinguish analogue dimmable loads or for control of non-dimmable
lighting loads. The detector incorporates Ex-Or’s OneSwitch Dimming,
allowing local manual operation of any controlled lighting load.
Electrical Connections
The detector should be connected in accordance with the diagrams opposite.
Each luminaire to be controlled must contain an analogue regulating type
ballast with the appropriate analogue input. Ballast types must not be mixed.
The analogue input terminals on the ballasts should be connected in parallel
with each other and to the analogue 1-10V output terminals on the rear of the
detector, observing the polarity. Also each of these analogue regulating
ballast Live inputs (maximum load 6 Amps) must be provided by the Volt-free
output (see 1st Wiring Example) from the detector.
When switching via the volt-free output multiple MS2421A detectors may be
connected in parallel provided the controlled load does not exceed 6 Amps.
(see 3rd Wiring Example).
DO NOT CONNECT DIMMING OUTPUTS TOGETHER .
OneSwitch
OneSwitch Dimming affords local control to the end-user whereby a simple,
momentary, push-to-make wallswitch can be used to raise or lower the lighting
level or toggle the output of the unit ON or OFF. A short press (less than
1 second) toggles the relay output from OFF to ON or from ON to OFF. A long
press will ramp the analogue output either 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.
Sensitivity to Movement
While the factory settings will be correct for many applications, the sensitivity
can be adjusted if required.
ON Sensitivity (ON Range):
This sets the detector’s range when the lights are
ON. (i.e. the space is Occupied) Choose setting from 1-100 where 1 is lowest
and 100 is maximum. (Note: Choose the lowest level possible to give
adequate detection.)
OFF Sensitivity (OFF Range):
This sets the detector’s range when the lights
are OFF. (i.e. the space is Unoccupied/Vacant) Choose % setting from 10% to
100% where 10% = 10% of ON Sensitivity and 100% = same as ON Sensitivity.
This is an approximation and should be tested on site during commissioning.
Generally the OFF Sensitivity should be significantly less than the ON
Sensitivity as in the ON/Occupied state small movements of e.g. seated
persons must be detected while in the OFF/Vacant state only the gross
movements of persons entering the space need to be detected. This
differential sensitivity prevents false triggering of the Presence Detection logic.
Like all programmable parameters, the sensitivity settings will be retained in
the event of a power failure and can be re-programmed any number of times.
Commissioning the Photocell
Commissioning the setpoints for Photocell based control requires the HP2000
Hand-held Programmer.This tool should be used aimed squarely at the front of
the Detector/Photocell at a distance of 1m although it can work at substantially
greater distances if aimed carefully.
Regulating Only:
For this mode the PCELL RLY action should be set to
“DISABLED” and the lights will be on continuously during periods of
occupancy. The Analogue 1-10V output dims the ballast(s) in the luminaires.
It always tries to maintain a programmed light level on the working plane. It
aims for the level stored in the parameter Set-point Low.
Sometimes it is convenient to limit the extent to which the presence detector
with photocell is allowed to dim the light output of the luminaire(s). This can be
done by setting the "DIMMING" parameter. This setting determines the range
over which dimming can be operated e.g. setting 80% allows the lumiaires to
be dimmed down to a minimum of 20% of its possible output as natural light
strengthens.
If it is desired to operate the lighting without any automatic photocell based
control over the dimming process, (e.g. only manual control of dimming, by
OneSwitch, and/or scene setting by HC5 Infrared Hand-held Controller is
required) then the default values of 1023 should be retained in the parameters
Set-point Low and Set-point High.
Programming the Regulating level:
Place a light meter on the working
plane underneath the presence detector with photocell. Adjust the light output
of the luminaire up or down manually by infrared. (On the HP2000, select
“UTILITIES” from the Main Menu and then “SET LIGHT LEVEL” from the
UTILITIES Menu. The up and down Arrow keys allow adjustment of the light
level up and down whilst pointing the handset at the presence detector with
photocell.) When the light meter reads the desired level, press and hold the
central “OK” button until the lights “blink” to acknowledge that the

Location
This
it be installed on a rigid surface that will not itself be subject to movement or
vibration.
Please note that microwave detectors are not recommended for applications
where there are large surface areas of metal, e.g. metal ceiling or floor tiles, as
unpredictable sensitivity may result.
The units are graded according to four variations in operating frequency. Each
type can be identified by different colour-coding on the detector label and
carton. For reliable operation it is essential that units of the same colour code
do not occupy adjacent positions in open-plan areas or in adjoining rooms (see
below).
is an extremely sensitive movement detector; it is essential therefore that
Note:
Should it be necessary to order additional detectors for an existing
installation and specific colour-coded detectors are needed, please add the
following suffixes to the part number: Y = Yellow, B= Blue, G= Green, R = Red.
(There is normally no need to specify the colour codes, as orders are
dispatched with a suitable colour code mix.)
Fixing
MS2421ASM - The housing may be secured to a hard surface or a BESA box.
The unit fits into the housing with a simple bayonet action.
MS2421AF - Depth required behind ceiling: 62mm from front flange plus an
allowance for the minimum bend radius of the cable. Sinking box fits into a
89mm diameter hole in ceiling tile or plasterboard ceiling. To avoid damage to
ceiling tile, do not overtighten. No access above the ceiling is necessary.
Please note: Do not position this product on a pitch narrower than 5m.
Do not mount within 0.25m of a luminaire.
