Examples of MR1500P and WMK application
Horizontal installation
For general applications where ceiling
mounting is not convenient and wide angle
coverage in the horizontal plane is desirable.
The WMK can be screwed to a hard surface
or the lid of a conduit stop-end box.

Vertical installation
Use this method of
mounting for racking aisle
applications and where
adjustment in the vertical
plane will give improved
control over the precise
point of entry detection.
Fixing
Commissioning
Only suitably qualified personnel should install this equipment.
CAUTION: Hazardous voltages inside the unit; take care and use an
insulated small terminal screwdriver to adjust the controls.
1. The Mid Range LightSpot is an extremely sensitive movement
detector; it is essential therefore that it be installed on a rigid surface
that will not itself be subject to movement or vibration.
2. Before isolating the circuits to be switched, check that all lighting is
fully operational and that there is no moving equipment or machinery
within the monitored area which may cause nuisance switching.
3. Position the detector where it has a good “view” of the area to be
controlled. Ideal mounting location is normally in a corner by the
entrance or at one end of a corridor at a height of 2.5 to 4m. Do not
mount within 0.5m of a fluorescent fitting.
Please note that this product uses microwave technology to detect
occupancy and is not recommended for applications where there are
large areas of metal, e.g. metal ceiling or floor tiles, as unpredictable
sensitivity may result. The detectors are extremely sensitive to
movement; they must be mounted on a solid surface which has no
movement whatsoever.
4a. MR1500P - Surface version
Separate the detector from its back-box by loosening the locking
screw so that approximately 3mm of thread is visible and then twisting
the detector off the back-box. Note the arrow symbol moulded into the
bottom of the back-box. The fixing holes allow for mounting on a
BESA box or direct to a rigid surface. Secure the back-box firmly to a
rigid surface so that the arrow points into the controlled area.
4b. MR1500PF - Semi-flush version
Use a hole saw to drill a 76mm hole into the ceiling tile. The flush ring is
designed to clamp the tile between its two halves. Loosen the locking
screw so that approximately 3mm of thread is visible and remove the
bottom half of the flush ring. With the detector in the ceiling, pointing
towards the area to be controlled, fit the bottom half of the flush ring to
the assembly. Depending on the thickness of the ceiling tile, screws
longer than those supplied may be required to hold the two halves of the
flush ring together.
Slide open the controls door on the side of the detector and set the
photocell control fully clockwise. Set the other three controls fully anticlockwise. Ensure that any heating/ventilation plant, which may cause
interference due to their vibration, is switched ON. Apply power to the
detector and commission strictly in order as follows.
1. Check that the detector has a good “view” of the controlled area.
2. ON RANGE Sets the detector range when the lights are ON. When
fully anti-clockwise, the green LED flashes in response to movement
and the range will be only a few metres. Move the control clockwise
so that the LED flashes in response to typical movements expected in
the controlled area. Always adjust to the lowest setting consistent
with required performance to minimise nuisance switching.
3. OFF RANGE Sets the detector range when the lights are OFF. When
set fully anti-clockwise, the range is the same with the lights ON or
OFF. Wait outside the area for the lights to go OFF. Re-enter the area
and check the point at which the lights come back ON. Increase the
setting until the lights come ON only as the area is actually entered
and not sooner.
4. PHOTOCELL The photocell holds lights OFF when the area
becomes occupied in bright conditions. It will not switch lights OFF in
an occupied area. Anti-clockwise adjustment makes the photocell
more active so that lights will be held OFF until it is darker. A mid
setting is generally suitable. The photocell may be overridden by
switching the manual light switch OFF then ON.
5. DELAY Sets the delay from the last detected movement after which
the lights will switch OFF. When fully anti-clockwise, the delay is
about 10 seconds which is used only for walk-testing as in the earlier
commissioning procedures. The maximum delay is 20 minutes. For
most applications set to mid position to give 10 minutes delay.
6. Slide the door closed.
It is recommended that Mid Range detectors be ceiling mounted.
Where this is not possible, the wall-mounting kit (WMK) must be used.
Electrical Connections
R1 and R2 are the terminals of a single pole, normally open, volt-free
contact. To use the incoming supply to power a load, one of these
terminals must be linked to the incoming supply. Terminal 3 has been
provided to facilitate this connection. Fit the supplied external link
between terminals 2 and 3. Terminal 1 will now become live when the
relay operates.

Connection
The method of connection will depend upon the application. Most
commonly, a single 4-core cable is used to connect the detector to the
nearest luminaire in the group to be controlled. The cable should have a
cross-sectional area of 1.5mm2. Use the 20mm hole in the back-box
(MR1500P only) for cable access and connect as shown below.

Note that L and L are internally joined, there is no internal connection to
the earth terminal and the two unmarked connections are not used.
Check that the wiring is correct and that the terminals are securely
tightened. Carefully offer the detector to the back-box, aligning the arrow on
the detector label with the arrow on the back-box, push home and twist to
click into position. Lock in place by tightening the locking screw. Do not
over-tighten.
Note: A means for disconnection must be incorporated in the fixed
wiring in accordance with the current wiring regulations.
