3 PIR Coverage

The MLB/WPRO500C should be installed within the height range 2.0m to 2.5m.

(See Fig. 2).

The unit has an adjustable lens with two detection zones.

• The outer zone covers an angle of 240º to a distance of approx. 3m to 16m at an

installation height of 2.3m. (See Fig. 3).

• The inner zone covers an angle of 360º which allows detection immediately

behind the MLB/WPRO500C. (See Fig.4).

• Fig. 4 also shows the variation of sensitivity with angle of approach for a person

moving within the detection area.

A Installation Procedure

a. Read the instruction manual before installing the MLB/WPRO500C.

b. Make sure the mains power supply has been disconnected.

c. Decide the best location to install the unit bearing in mind the most sensitive

direction of movement shown in Fig. 4.

Then ensure that the top of the ﬂoodlight is no closer than 200mm to the surface

above it and it is no closer than 500mm to the surface at the side of it.

(See Fig. 6).

Also ensure that any surface directly illuminated by the ﬂoodlight is at least 1m

away from the front glass. (See Fig. 8).

Do not mount the unit base on a horizontal surface such as a sofﬁt,

(See Fig. 7) or on an inﬂammable surface such as wood or plastic.

Cautions in use:

• If the ﬂoodlight glass is cracked, replace it immediately before further use.

• The surface of the ﬂoodlight cover and glass get extremely hot when the lamp

has been on for some time. Do not touch and keep combustible materials away.

• Additional lighting of up to three 500W class C ﬂoodlights or 1.5kW of other

approved ﬁlament lighting may be connected. (See Fig 12).

d. Install bulb:

1. Remove the lamp cover screws retaining front glass frame (See Fig. 9) and swing

the glass frame away from the ﬂoodlight cover.

2. Check that the bulb and ﬁtting contacts are all clean, ensuring that you hold the

bulb with a clean dry cloth during this and subsequent procedures.

3. Locate one of the bulb contacts onto one of the ﬁtting contacts and push back

the contact spring at the other end inserting the bulb contact into its ﬁtting

contact. check that the bulb contacts at each end are properly located and that

there is reasonable pressure on the bulb contacts. (See Fig. 10).

4. Tighten the ﬂoodlight cover screws ﬁrmly to ensure weatherproof rating.

e. Make backplate holes and cable up:

Decide which of the four 20mm dia. cable entry holes on the back plate you wish to

use (there are 2 rear entry and 2 bottom entry).

if you wish to use additional lighting a second entry point will be required (a manual

override switch can be accommodated by a single entry of 4 core cable). Firstly cut

undersize holes as required in the blind grommets supplied. This way sealing against

moisture inﬂux is maintained. Then score around the outside edge of the circular

groove marking the hole with a sharp knife and gently tap out the centre. Do the same

to the second entry point if necessary and ﬁt the grommet(s) supplied and push the

cable(s) in to give sufﬁcient length to make a connection for all the cable wires.

f. Fix backplate:

Fix the backplate onto the wall with the large pan head screws supplied using

wall plugs if necessary (See Fig. 11) remembering the cable entry holes are on the

bottom. connect cable wires as necessary. (See Fig. 12).

g. Insert the sensor light onto the backplate (See Fig. 13). Then ﬁx with the two

small c/sk head screws supplied. (See Fig.14).

Fig. 12a

B Installation of Corner Mounting

Adapter (Option)

a. Make hole(s) in the wall plate as required and insert grommets.

b. Make hole(s) if any in the corner mounting adapter (none will be required if only

the bottom entry hole(s) are in use on the backplate).

c. Fix the backplate to the corner mounting adapter using the 3 large pan head

screws supplied (used to ﬁx the backplate to the wall when the adapter is not

in use).

d. Proceed as for (Ae) above, ﬁnally ﬁxing the

corner mounting adapter and backplate

assembly onto the corner using the 2 pan

head screws supplied and wall plugs if

necessary. The holes used are on the outside

edges of the corner mounting adapter.

(See Fig.15).

C To Avoid Nuisance Triggering

Your motion sensor may be activated by animals, light reﬂective surfaces, heat

sources, or movement of objects. The following guidelines will help you avoid

nuisance triggering.

• Do not aim the sensor toward lights of any kind. (See Fig. 16, 17). Aim the sensor

and light in a different direction.

D The Adjustments of MLB/WPRO500C:

a. Adjustment of the sensor head

The bottom part of the sensor head can be horizontally rotated 60º to right or

left. (As shown in Fig. 20).

b. Adjustment of the ﬂoodlight

You can adjust horizontally right or left 45º. (See Fig. 21).

c. The Adjustment of LUX, METER and TIME

The MLB/WPRO500C has three adjustable knobs, LUX, METER and TIME on the

underside of the sensor head.

• The LUX knob can be set to allow the MLB/WPRO500C to operate at any light

level between full daylight and almost complete darkness.

• The METER knob reduces the forward PIR range from around 16m to around 3m.

• The TIME knob can adjust the time (a period between 6 seconds and

approximately 12 minutes) for the light to remain “ON” after the last detection.

Following the adjustment procedure below, you can adjust the ﬂoodlight vertically

up 50º and down 35º. (See Fig. 22).

1. Loosen plastic light head screw by hand (See Fig. 23).

2. Adjust ﬂoodlight to the desired elevation.

3. Tighten the plastic light head screw ﬁrmly.

• Avoid aiming the sensor towards objects which may move in the wind, such as

bushes. (See Fig. 18).

• Avoid mounting the sensor near heat sources, such as heating vents, air

conditioners, dryer vents or lights. (See Fig. 19).

• Avoid directing the sensor toward areas or objects whose surfaces are highly

reﬂective such as pools or are subject to rapid temperature change.

5 Function and Operation

A Lens Shield - function

The lens shield contains 13 segments each of which can be broken in half. Each

segment can block 10º detection angle within the ﬁeld of view by pressing it onto

the outer ring of the sensor head. (See Fig. 25).The segments only work on the

outer 240º zone. The inner 3m radius zone is unaffected.

• How to use:

1. Take the outer ring off the sensor head. (See Fig. 24).

2. Decide on the detecting zone (or zones) that you want to be reduced or blocked.

3. Insert the lens shield segments into the slot of the outer ring as following

illustration (See Fig. 25). Then put the outer ring back into position on the sensor

head. The example shown will have blocked a 30ºdetection angle within the

outer 240º zone.

4. By breaking the outer section of a segment or group of segments the range at

that position in the outer zone will be reduced from 16m to 7m and not 3m.

B Walk Test

The MLB/WPRO500C will start working automatically approx. 3 minutes after the

power is switched ON.

Set the TIME knob to “6 sec.”, the LUX knob to “ ” and the METER knob to

“+” (Factory Presets).

You can start the “Walk Test” in any ambient light level and the light will go on

for about 6 seconds after each detection. While the light is ON and for 2 seconds

afterwards the person carrying out the walk must remain stationary before

continuing on the path shown in Fig. 25.

• How to adjust your desired detecting area(s):

1. Follow Fig. 25 and start the Walk Test across the detection zones to check that the

light under control comes on when entering or leaving a zone. Repeat it and adjust

the METER knob or sensor head until you are satisﬁed with the detection area.

2. To eliminate unrequired detection zones you need to use the lens shield (see 5A

Lens Shield - function).

Notes:

• When using the lens shield or adjusting the knobs, be careful not to damage the lens.

• Conditions below may cause reduction in sensitivity of the sensor.

a. On very foggy nights, sensitivity may be less due to moisture on the lens.

b. On very hot days, sensitivity may be less due to the temperature of the human

body being close to the temperature of the surroundings.

c. On very cold days little heat will be emitted from the body with heavy clothing

and head covering. This may reduce the sensitivity of the sensor.

d. Soap or polish may damage the sensor lens and can cause reduced sensitivity.

Clean with a soft damp cloth only.

6 Troubleshooting

Each MLB/WPRO500C has undergone rigorous testing under ISO9002 quality

control procedures before it leaves the factory. Malfunctions are most often due to

incorrect installation or adjustment of the unit. If you are experiencing problems,

please check the following ﬁrst.

Possible Solution

1. Check if all wiring connections are correct.

2. Turn off power for at least 10 seconds, then on again.

3. Check if all light ﬁxtures are working properly, and the power is

connected correctly to the MLB/WPRO500C.

4. Check if the bulb is seated ﬁrmly with good contacts.

5. Check if the LUX knob is adjusted to the desired light level.

6. Check if the detection angle is right and aimed at the desired area.

1. Set the TIME knob to minimum and check again.

2. Make sure that the unit is not installed looking towards objects

which may move in the wind, such as bushes and that the unit is

mounted securely.

3. Stay away from the detection zone to avoid activating.

4. Make sure that the unit is not looking toward any areas or objects

which have surfaces that are highly reﬂective or are subject to rapid

temperature change, such as pools, air conditioners or heating vents.

5. Check if all wiring connections are correct, or if the main power

supply has been inadvertently connected to the L1 (Switched Live)

terminal.

1. Check if there are any white or reﬂective surfaces in the detection

area and adjust the sensor to a different direction or adjust the lens

shield.

2. The sensor is more sensitive in winter. Please check again when the

temperature gets back to normal.

Rain, snow and storm can create big temperature changes that

activate the sensor. False triggering can be minimised by installing the

sensor in a protected location or to minimise the detection distance

using the meter control.

Fig. 27

C Setting of LUX, METER and TIME Knobs

for Automatic Operation (See Fig. 27).

When Walk Tests are complete, the unit can be set up for Automatic mode.

The TIME setting controls how long the unit remains illuminated following activation

and after all motion ceases.

The minimum time (fully anti-clockwise) is approx. 6 seconds, whilst the maximum

time (fully clockwise) is approx. 12 minutes. Set the control to the desired setting

between these limits.

The DUSK (LUX) control determines the level of darkness required for the unit to

start operating. The DUSK adjustment knob is indicated by the “Moon” and “Sun”

legends. We suggest an initial DUSK setting of between 2/3 and 3/4 of the way

round from the “Sun” towards the “Moon” setting.

The METER control will allow you to set the detection distance from 3 meters up to

a maximum of about 16 meters.

Adjust the METER knob as necessary to reduce the coverage until it meets the users

preference.

Note: Up to a radius of approx. 3m from the ﬂoodlight sensor there is 360º

detection coverage which is not adjustable..

• A small ﬂat blade screwdriver is applicable for all the above knobs.
