1. General Information
These instructions should be read carefully and retained for further
reference and maintenance.
2. Safety
• Before installation or maintenance, ensure the mains supply to the
sensor is switched off and the circuit supply fuses are removed or
the circuit breaker turned off.
• It is recommended that a qualified electrician is consulted or used for
the installation of this sensor and install in accordance with the
current IEE wiring and Building Regulations.
• Check that the total load on the circuit including when this sensor
is fitted does not exceed the rating of the circuit cable, fuse or
circuit breaker.

4. Installation
• Ensure the mains supply is switched off and the circuit supply
fuses are removed or the circuit breaker turned off.
• An isolating switch should be installed to enable the power to be
switched ON & OFF for maintenance purposes.
• Open the unit by gently prying the “ears” on each side of the unit
(See diagram “A”). This can be done without a tool, but if you prefer use
a flat blade screwdriver, but be careful not to damage the clips. The front
cover is hinged at the top and the front cover will swing open upwards.
• Mark the position of the fitting holes using the unit as a template.
Drill out the mounting holes taking care to avoid any joists, electrical
cables or water/gas pipes that may be hidden beneath the surface.
Insert the rawl plugs into the holes.
• Pass the 230V 50Hz mains supply and load cables through the cable
entry points on the unit, ensuring the grommet(s) is used to maintain
the IP rating of the sensor.
• Fix the unit to the wall using the correct screws for the
rawl plugs installed.
• Terminate the cables into the terminal block ensuring correct polarity
is observed and that all bare conductors are sleeved (See section 5.
Connection Diagram).
• Attach the supplied cable clamp ensuring not to overtighten.
• Close the front cover.

6. Testing
• The adjustment knobs located on the side of the sensor head
(see diagram “D”) are factory set to “Daylight Mode” i.e. LUX set
to the ‘Sun’ symbol.

• The Dusk setting determines at which light level the NSLD1000 will turn
its connected load “ON”. Turning this setting fully clockwise allows you
to test the circuit during daylight.
• Connect the unit to the mains and switch power ON.
• After a short delay, the unit will switch ON. This is indicated by the
red LED (See diagram “C”). Any attached lights will also illuminate.
7. Setting up for Automatic Operation
• The TIME control determines how long the lamp remains illuminated
after activation. There are 4 designated “time on” settings 2, 4, 8 hours
and dusk until dawn.
• The DUSK (LUX) control determines the level of darkness required
for the unit to start operating. The setting is best achieved by the
procedure below;
1. Set the Dusk control knob fully clockwise and the Time control to the
required number of hours or dusk/dawn.
2. When the ambient light level reaches the level of darkness at which
you wish the lamp to become operative (i.e. at dusk) SLOWLY rotate
the control in an anti-clockwise direction until a point is reached
where the lamp illuminates.
3. Leave the control set at this point.
• At this position the unit should become operative at approximately
the same level of darkness each evening.
• Observe the operation of the unit. If the unit is starting to operate too
early (i.e. when it is quite light) adjust the control slightly anti-clockwise.
If the unit starts to operate too late (i.e. when it is very dark). Adjust the
control slightly clockwise.
• Continue to adjust until the unit operates as desired.

8. Troubleshooting
Problem
• PIR sensor will not
operate at night.
Solution
The level of ambient light in the area may too
bright to allow operation at the current DUSK
setting. During the hours of darkness first turn
the Time Delay knob to minimum then adjust
the DUSK control slowly anti-clockwise until the
lamp illuminates. Refer to previous section for
more details.
Adjust the setting anti-clockwise to lower the
level of ambient light required for activation.
• PIR activates during
the daytime.
