accordance of the current IEE Wiring Regulations

• The DX4130 is designed to be used in conjunction
with Dimplex heaters up to 3kW electrical loading.

• Only to be used on a 220-240Volt A.C. ~ electricity
supply

• Electricity supply must be isolated before
commencement of installation

• Always isolate the detector switch and the heater
from the electricity supply before undertaking any
maintenance work

• Must not be installed and used in the vicinity of a
bathroom or swimming pool

Installation

(Please also refer to the IMPORTANT SAFETY ADVICE)
Before undertaking installation work, ensure the electricity supply is disconnected from any relevant fixed wiring.

Supply cable is not provided with this product, and it should therefore be installed by a competent person or electrician
This PIR detector must be used on an A.C. ~ supply only
Dimplex Quartz and ceramic heaters operate by emitting radiant heat within a specific area or zone.

The beam of radiant heat will interfere with the correct performance of the PIR detector unless the PIR detector is mounted outside the ‘throw’ of
radiant heat. It is therefore essential that the PIR detector is mounted as outlined below:

1. For installation of Quartz and ceramic heaters, please refer to the relevant installation instructions.

2. The PIR should be positioned to cover the desired sensing area without obstruction, avoiding the direct ‘throw’ of the heater.

3. The PIR should be wired directly back to a type C MCB or 13 amp re-wireable fuse. The cable should not exceed 2.5mm².

4. Remove screws and disconnect the plug connecting the detector to the key box. When removing the detector head, the latch on plug
should be released as indicated. (see Fig.1.)

enable Dimplex Quartz and ceramic heaters (or any other heater up to
3kW) It automatically switches the heater on and off, depending on
whether the area below the heater is occupied.

Features

• Time delay adjustment

• Full 180º coverage over 15m if required

• Size of detection area can be reduced

• Approved to VDE 0632 and IEC 669-2-1

• Separate wall-box and plug in detector lead to simplify installation

• IP54 rated

7. Mark position of remaining fixings, remove box and complete fixing.

8. Fix the wall box to the wal l, ensuring the drain hole is at the bottom.

9. Cable entries are made to the base of the box, using the holes provided.

10. Connect circuit wiring to terminal block. (see Fig.2.)

11. Plug detector head into the back box socket.

Secure detector to wall box with screws provided and cover screws with screw caps.

Adjusting PIR Range

Limit the range and angle o f detection as appropriate by adjusting the detector head and by using the lens masking plates
provided. Cut the appropriate segments from the lens m ask to cover the area of the lens that requires masking.

Testing

1. Set the light level 5 to maximum (clockwise), and the time on  to minimum (anti-clockwise).

2. Move in and out of detection pattern checking the PIR detector switches load on and then off. Once the detection area has been set
satisfactorily, adjust the time (blue knob) to the desired level. For your convenience optimum settings have been indicated.

3. If the unit does not operate, refer to the check list and fault finding list.

Check List

1. Check the supply to the detector

2. If the unit is being tested during daylight , ensure that the photocell has been adjusted in accordance with point 1 in the ‘Testing’
section.

3. Check detector is connected to the heater correctly

Fault Finding List

Problem Solution

The unit will not switch on

Unit is detecting at too long a range

Unit switches on for no apparent
reason

Unit will not switch off

• Check power is supplied to the unit

• Check the plug in connection from the detector head is inserted in to the wall box correctly

• Check to see that the lamps are fitted correctly to the heater(s)

• Check mounting height and adjust angle of the unit downwards to reduce range (note the unit is

designed to switch at a maximum of 15 metres with 170Ib (77kg) person walking at 90º to the
unit. Alternatively fit an appropriate mask.

IMPORTANT: at 10ºC this unit may detect in excess of 20 metres.

• Check the unit is not sited near any vents or heating flues

• Infra-red patterns are given off by electrical appliances

NOTE: to reduce sensitivity, blank off areas C1, C2, C3, C4 of the lens mask

• Are you standing by the detection zone? Whilst you are moving in and out of the detection area
the unit will continue to detect. The heater on time is from the last moment detection was made.
