Security

For details of securing the product and system see the General Security Best Practice for Ex-Or Products Information Sheet – D6004.

Determine Position

The Mxx3421 & Mxx3500 sensors are extremely sensitive movement detectors. They must be installed on a rigid surface that will not be subject to movement or vibration. They 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. Microwaves can penetrate lightly built partitions, glass, etc. Movement in adjacent spaces may cause spurious triggering if the orientation and sensitivity setting of the detector is not managed carefully.

Mxx3421

Do not mount within 0.25m of a luminaire. Max distance between sensors = 5m

Recommended maximum mounting height	3m
Range	Cone-shaped detection pattern, diameter (at floor level) = 2.8 x

mounting height

Determine Position

Mxx3500

Position the detector where it has a good ‘view’ of the space to be controlled. An ideal location is in a corner adjacent to the entrance of a room or at one end of a corridor. Do not mount within 0.25m of a luminaire.

Recommended maximum mounting height	3.5m
Range	Adjustable up to 20m

Plan DALI Cable Runs

DALI Topology

DALI permits a free topology which means wiring can be done in daisy chain, star or a combination of these. Do not close the loop or ring connections.

Attach Conduit Fittings & Cable Glands to Lower Housing (if required)

$Attach Conduit Fittings & Cable Glands to Lower Housing $if required$$

Prepare Mounting Location and Run Cables

The sensor may be mounted to any suitable surface, but is most commonly fixed to a conduit stop-end (BESA) box or bushed to trunking. change image

Make Electrical Connections

Make the electrical connections to the sensor – see “Make Electrical Connections”

Fix to Ceiling

8 segments on the collar allow up to four different rotational positions for the sensor, when inserting the tabs into slots (1-8).

DALI Bus Connections – DALI variants

To prevent loose strands being outside the terminal a tool, e.g. a screwdriver, must be used to push the button on the terminal when stranded conductors are inserted.

Warning: Do not connect to 230V.

Warning: The DALI Bus is not classified as SELV. The same procedures and safeguards must be applied as when working with mains voltage.

Perform Walk Test

In order to verify correct installation, walk testing is recommended. Follow the instructions provided with the QuicksetPro (QSP). During the walk test the connected lights will be switched off until movement is detected.
Perform Walk Test
Stand out of the unit’s viewable footprint or remain motionless within the viewable footprint and wait for the lights to go out.

Wait a further 2 seconds for the unit to stabilize then make a movement, the lights should come back on. Observe that the detection / non-detection is as expected.
