NOTE:

 Wires should be 

stripped 13-14.5mm 

for best fit with the 

push-fit terminal block.

The PIR sensor scanning specifications 

(approximately 8 metres at 120°) may vary slightly 

depending on the mounting height and location.

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:

01)  Undo the screws at the top and bottom of the 

fitting and lift off the front.

02)  Undo the screw in the plastic cover at the bottom 

of the fitting and remove the terminal.

03)  Using the back of the fitting as a template, mark 

the location of the fixing holes.

04)  Pierce the rubber grommet in the back of the 

fitting. Make the hole as small as possible so that 

a good watertight seal is maintained when the 

cable has been threaded through.

05) Thread the cable through the grommet.

06)  Secure the fitting to the wall using fixings 

(supplied). If the fixings supplied with your fitting 

are not appropriate to your installation, select 

suitable alternatives.

07)  Make the connections to the terminal block 

according to the colour code.

08)  Replace the cover and tighten the screw.

09)  Replace the front of the fitting and tighten the 

screws.

10) 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.

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.

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.

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.

 

CLEANING:

To avoid dust build-up and ensure proper 

functioning of the half lantern light, please wipe the 

sensor lens lightly with a damp cloth every 3 months.

Disconnect the power and clean the exterior only of 

this fitting with a moist (not wet) cloth.

Do not use any chemical or abrasive cleaners.

 

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
