Note
Please read this manual carefully before installing the sounder.
Application
The EEx Sounder dHE is a signalling device that generates various signalling tones and
signalling tone sequences and emits them at a high sound pressure level. The user may
choose between 31 preset signalling tone groups and one programmable one. Every
signalling tone group contains 4 different signalling tones. Wire the control inputs with
floating contacts or jumpers in order to chose any one of these 4 signalling tones. The
sounder has 8 volume levels. All outer fastening parts are made of non-corrosive materials.
The stable, all-plastic housing conforms to protection degree IP 66, which means the
sounder can be installed both indoors and outdoors. Explosion category II 2 G EEx dem
IIC T6 allows the sounder to be operated in hazardous areas of zones 1 and 2.
Setting the volume and the signalling tone groups prior to mounting the sounder
The sounder ships with the following setting:
Sound pressure: maximum
Signalling tone group: Group0:
continuous tone 1000 Hz; sweeping tone 1200 Hz / 500 Hz;
intermittent tone 1000 Hz
Selected signalling tone: continuous tone 1000 Hz
If you want other signalling tones and volume levels, please follow the instructions below.
To set the sound pressure level and the signalling tone groups, open the sounder housing.
To do this you have to place the sounder on a level surface, the loudspeaker opening facing
upwards. Loosen the 8 housing screws and lift the upper part of the housing slightly. Detach
the connecting cable running from the loudspeaker to the circuit board at the circuit board
and put the loudspeaker part aside. In the bottom part of the housing, on the circuit board,
you will find the controls and an LED that are required to set the signalling tone groups.

Procedure for setting the sound pressure level
The programming procedure described below must be performed outside of
hazardous areas only, because the opened device has to be supplied with voltage
during the procedure.
Turn the rotary switch S1 (Vol./Prog. Select 0..F) to a position between 0 and 7. Position 7
represents the maximum sound pressure level. For each of the positions 6 through 0 the
sound pressure level is reduced by 3 dB(A).
Procedure for setting a signalling tone group
The active signalling tone group determines the 4 signalling tones that may be selected
from the control inputs during operation.
Setting the active signalling tone group
a.) From the table „Signalling tone groups“, select the group to which the 4 signalling tones
belong that you want to select by connecting the control inputs during operation.
b.) If the selected signalling tone group belongs to one of the groups Group0 to GroupF,
place the jumper in jumper field X1 in position LS. Otherwise, place the jumper in
position US. Turn the rotary switch S2 (Group/Tone Select LS:0..F US: 10..1F) to the
position corresponding to the last character of the line name of the selected signalling
tone group. For instance to position A for the selected signalling tone group GroupA or
to position 5 for the selected signalling tone group Group15.
For the signalling tone group GroupF, the composition of the 4 signalling tones is freely
programmable. Any one of the signalling tones Tone0 to Tone1F from the table “Signalling
tone description” may be freely assigned to the settings Stage 0, Stage 1, Stage 2 and
Stage 3. This programming procedure is described in greater detail below.

5
Signalling tone group GroupF programming procedure
Any one of the signalling tones from the table “Signalling tone description” may be freely
assigned to the settings Stage 0, Stage 1, Stage 2 and Stage 3 of the signalling tone group
GroupF, in order to compose exactly the 4 signalling tones in signalling tone group GroupF
that are required for a certain application.
Programming the signalling tone group GroupF
a.) First, turn the rotary switch S1 (Vol./Prog. Select 0..F) to one of the positions 8, 9, A or
B, in order to force the device into the “mute” setting when the mains supply is switched
on.
b.) Turn on the mains supply of the device. The device goes mute and LED H1 is switched
on.
c.) In order to change a particular signalling tone, use the rotary switch S1
(Vol./Prog. Select 0..F) to select the corresponding setting among the Stage 0, Stage 1,
Stage 2 or Stage 3 settings of signalling tone group GroupF. Do this by turning the
rotary switch S1 to position 8 (Stage 0), 9 (Stage 1), A (Stage 2) or B (Stage 3).
d.) Select the desired new signalling tone from the table “Signalling tone description”.
e.) If the selected signalling tone belongs to the tone interval Tone0 to ToneF, place the
jumper in jumper field X1 in position LS. Otherwise, place the jumper in position US.
Turn the rotary switch S2 (Group/Tone Select LS:0..F US: 10..1F) to the position
corresponding to the last character of the line name of the selected signalling tone. For
instance to position A for the selected signalling tone ToneA or to position 5 for the
selected signalling tone Tone15.
f.) Press push button S3 (Enter) to trigger the programming procedure. LED H1 will be
turned off during programming, and then on again after the programming is completed.
Repeat steps c.) to f.) for all the settings of those tones of signalling tone group GroupF
that you want to change.
g.) Turn off the mains supply of the device.
h.) Turn rotary switch S1 (Vol./Prog. Select 0..F) back to the preferred volume setting
between position 0 and 7, place the jumper in jumper field X1 in position LS, and turn
rotary switch S2 (Group/Tone Select LS:0..F US: 10..1F) to position F.
Pick up the loudspeaker part of the housing again, connect the loudspeaker cable with the
circuit board in the lower part and place the loudspeaker part on top of the lower part.
Connect the housing parts with each other using the 8 housing screws.

Setting the volume and the signalling tone groups following sounder mounting
If the signalling tone and sound pressure level settings must be changed after the device
has been mounted, the sounder must be dead (no-voltage). Wait more than 15 minutes
before opening the device.
Loosen the 8 housing screws and lift the upper part of the housing slightly. Detach the
connecting cable running from the loudspeaker to the circuit board at the circuit board and
put the loudspeaker part aside. Perform the setting as described above.
Warning:
The programming of signalling tone group GroupF must be performed outside of
hazardous areas only, because the opened device has to be supplied with voltage
during the procedure.

Possible applications
Single sounder with a fixed signalling tone:
You have selected a signalling tone group according to the procedure described earlier in
this manual. To select a fixed signalling tone (Stage 0, Stage 1, Stage 2 or Stage 3) from
the signalling tone group, the control inputs must be connected accordingly. The control
inputs are the terminals 3, 4 and 5, located in the sounder’s electrical enclosure. Place the
sounder with the horn opening resting on a level surface, loosen the 6 screws of the
electrical enclosure lid and remove the lid.
Perform the setting of a fixed signalling tone as follows:
Stage 0 No connections
Stage 1 Connect terminal 3 and terminal 4 using a jumper
Stage 2 Connect terminal 4 and terminal 5 using a jumper
Stage 3 Connect terminals 3, 4 and 5 using a jumper.
Single sounder with variable signalling tone:
If there is a requirement for the ability to select the individual signalling tones of a signalling
tone group (Stage 0, Stage 1, Stage 2 or Stage 3) during operation, terminals 3, 4 and 5
must be connected accordingly to the floating contacts of a control device. This may be
prepared at this stage, or after the sounder has been mounted.
Select a signalling tone via floating contacts k1 and k2 as follows:
Stage 0 Both contacts open
Stage 1 Contact k1 closed, contact k2 open
Stage 2 Contact k1 open, contact k2 closed
Stage 3 Both contacts closed

10
Multi-sounder with a fixed signalling tone:
If several sounders are being operated simultaneously with the same signalling tone, it
may be a good idea to synchronise the signalling tones, i.e. to make sure the signalling
tones of all the sounders sound for an equally long period of time. This is only possible with
the signalling tones for which “Sync” has been ticked off in the table “Signalling tone
description”. To enable synchronisation, the terminals 3 of all the sounders, the terminals 4
of all the sounders and the terminals 5 of all the sounders must be interconnected.
To select a fixed signalling tone (Stage 0, Stage 1, Stage 2 or Stage 3) from the set
signalling tone group, the control inputs of one of the sounders must be connected
accordingly. This may be prepared at this stage, or after the sounder has been mounted.
Perform the setting of a fixed signalling tone as follows:
Stage 0 No connections
Stage 1 Connect terminal 3 and terminal 4 using a jumper
Stage 2 Connect terminal 4 and terminal 5 using a jumper
Stage 3 Not a useful setting in this application, as synchronisation is not possible
when terminals 3, 4 and 5 are interconnected.
Multi-sounder with variable signalling tone:
As „Multi-sounder with a fixed signalling tone“, except that the signalling tone may be
chosen via floating contacts of a control device.
Select a signalling tone via floating contacts k1 and k2 as follows:
Stage 0 Both contacts open
Stage 1 Contact k1 closed, contact k2 open
Stage 2 Contact k1 open, contact k2 closed
Stage 3 Both contacts closed. Please note that for this selection a
synchronisation of the signalling tones is not possible.

11
Mounting
The sounder is suited for wall and ceiling mounting. For mounting dimensions, see the
dimension illustration (on page 12). The wall bracket included in the box is fastened with 2
screws (∅6 or 8 mm). To connect, loosen the 6 lid screws and remove the lid. The
fasteners and the mounting surface must be able to safely carry the weight of the sounder.
Installation
Prior to leading the connecting sounder cables through the cable gland, 100 – 130 mm of
the isolation must be removed. Before connecting the single connectors to the terminals,
remove 8 to 10 mm of isolation from the connectors.

After connecting the loudspeaker, place the single conductors of the connecting cables
flatly across the connecting terminals, in the direction of the cable gland.
Warning! To avoid the connectors getting pinched, do not place them over the sealing
edge.
Use sufficiently long cables to facilitate positioning of the sounders at a later stage.
Close the lid
Prior to closing the lid, the sealing surfaces and the sealing must be checked for damage
and dirt, and cleaned if necessary. Damaged seals must be replaced by original seals from
the manufacturer.
Put the lid on. Make sure the lid sits straight, and that the „lid fastener“ has not been placed
across the threaded lid bolt or across the sealing edge. Then turn the lid screw as far as it
goes, and tighten lightly.
Positioning the sounder
Swing the sounder in the desired position and tighten both side screws on the wall bracket.
Operating position
In order to avoid a reduction of the volume due to dust, rainwater or other foreign matter,
the horn should be mounted horizontally or facing downwards.
Care and maintenance
The sounder is maintenance-free. In very dusty or dirty surroundings, the sounder should
nevertheless be cleaned with a damp cloth from time to time. Never use sharp objects for
cleaning.
Special operating conditions
In order to maintain the given listening quality, the sounder must not be mounted in close
vicinity of sources of magnetic fields with technically relevant frequencies.
