The detection range of the unit may also alter 

with temperature change. Before selecting a place 

to install your PIR lantern you should note that 

movement across the scan area is more effective 

than movement directly towards or away from the 

sensor (refer to Fig. 2 below).

If movement is made walking directly towards or 

away from the sensor and not across the apparent 

detection range will be substantially reduced (refer 

to Fig. 3 below).

INSTALLATION:

Please refer to Fig. 4 below.

1)  Remove the two screws at the top and bottom of 

the fitting and lift off the front housing.

2)  Position the fitting on the surface where it is to be 

installed and mark the mounting hole positions.

3)  Drill and plug the wall at the marked positions 

ensuring you pass the cable wire through rubber 

grommet.

4)  Screw and fix the back housing to wall with 

suitable mounting screws (supplied).

5)  Remove PIR terminal cover and expose the 

connector block and make connections according 

to the relatives symbols:

(L)  Brown wire  

(N) Blue wire.  

 
Make sure that terminals are tightened securely and 

that no strands of wire protrude.

6)  Replace and secure the plastic PIR cover.

7)  Insert suitable ES energy saving lamp.

8)  Replace the front housing and tighten the screws.

9) Restore the power and switch on.

 

INTRODUCTION:

The half lantern incorporates a PIR (passive Infrared) 

sensing device which continuously scans a preset 

operating zone and immediately switches the light 

on when it detects movement in that area.

This means that whenever movement is detected 

within the range of the sensor the light will switch 

on automatically to illuminate the area you have 

selected to light. While there is movement within 

range of the unit the light will remain on.

 

READ THIS FIRST:

Check the pack and make sure you have all of the 

parts listed on the front of this booklet. If not, 

contact the outlet where you bought this product.

This product must be installed by a competent 

person in accordance with the current building 

and IEE wiring regulations.

As the buyer, installer and/or user of this product it 

is your own responsibility to ensure that this fitting 

is fit for the purpose for which you have intended 

it. Eterna lighting cannot accept any liability for 

loss, damage or premature failure resulting from 

inappropriate use.

This product is designed and constructed according 

to the principles of the appropriate British Standard 

and is intended for normal domestic service. Using 

this fitting in any other environments may result in a 

shortened working life.

Switch off the mains before commencing installation 

and remove the appropriate circuit fuse or lock off 

MCB.

This unit is suitable for outdoor use.

This product is designed for permanent connection 

to fixed wiring: this must be a suitable circuit 

(protected with the appropriate MCB or fuse).   

Before making fixing hole(s), check that there are no 

obstructions hidden beneath the mounting surface 

such as pipes or cables.

Make sure that the fixings are strong enough to 

support the considerable weight of the fitting and 

hold it rigidly.

The lamp must be positioned so that there is at least 

0.5m (500mm) between the bulb and any illuminated 

surface.

When making connections ensure that the terminals 

are tightened securely and that no strands of wire 

protrude. Check that the terminals are tightened 

onto the bared conductors and not onto any 

insulation.

WARNING: 

This prodct becomes hot! 

This product is not intended to be used by children 

and persons with sensory, physical and/or mental 

impairments that would prevent them from using it 

safely.

IMPORTANT - Always switch off the mains power 

before changing the lamp.

You are advised at every stage of your installation to 

double-check any electrical connections you have 

made. After you have completed your installation 

there are electrical tests that should be carried out, 

these tests are specified in the current IEE wiring and 

building regulations. 

This product is double insulated, do not connect any 

part to earth.

 

WHERE TO FIT YOUR PIR HALF LANTERN:

To achieve best results we suggest you take the 

following points into consideration:

Do not mount on a surface that has vibration.

Ideally the PIR half lantern should be mounted 1.8 

to 2.5 metres (6 to 8ft) above the area to be scanned 

(refer to Fig. 1 below).

 

To avoid damage to the unit do not aim sensor 

towards the sun.

Avoid positioning the sensor unit adjacent to a 

bright light source which may prevent the unit from 

operating when the lux control is set to operate in 

dark conditions.

Avoid nuisance false triggering by directing sensor 

away from: 

    

Trees and shrubs 

Reflective surfaces such as smooth white walls 

Swimming pools  

Heat sources such as boiler flues

The PIR sensor scanning specifications 

(approximately 12 metres at 120°) may vary slightly 

depending on the mounting height and location.
