INTRODUCTION
These instructions relate to the installation, connection and setting-up of
an Imagine SCENECOMMANDER.
It is assumed that a suitable mounting site has be chosen and prepared,
and that all necessary connecting cables have already been installed to
the correct specification.
PREPARATION
Wall Back-box
Fascia Plate Options
Models ES9332, ES9334, ES9335, ES9338 and ES9339 are designed to be
fitted to a 46mm deep single-gang U.K. back-box (e.g. the Electrosonic
ES9330).
The SCENECOMMANDER is designed to be installed with a suitable fascia
plate which is supplied separately. The installation procedure depends
on the fascia type.
Models ES9348 and ES9349 are designed to be fitted to a 47mm deep
double-gang U.K. back-box (e.g. the Electrosonic ES9331).
Two types of flush-fitting fascia plate are available which use the
following installation methods:
If the back-box is fitted with top and bottom retaining tabs, these must
be removed or bent backwards to provide clearance for the control unit.
Consideration must also be given to conduit fittings which may protrude
into the back-box.
•
Screw Fixing
– available as standard in Polished Brass
or Brushed Stainless Steel.
•
Concealed Fixing
– made to special order only.
Component Check
Cabling
Check that the SCENECOMMANDER is supplied with the following
components:
Each SCENECOMMANDER requires an ‘input’ cable which comprises two
power wires and a screened data cable (from the local SCENESET module
and any preceding devices).
•
•
•
•
•
Control Unit
Spring Clips (2 off – fitted to top and bottom flange of control unit)
M3.5 Fixing Screws (2 off – held captive on each side of control unit)
Cable Clamping Plate
Self-tapping Screws (2 off – for clamping plate)
If any parts are missing or damaged, please contact your supplier
immediately.
Where a SCENECOMMANDER is being installed in the middle of the
data/power highway, there should also be an ‘output’ cable which will
connect to the next device in the chain.
To assist with installation and any future fault-finding, it is suggested
that each cable is labelled with its function (i.e. ‘input’ or ‘output’). The
connection procedure assumes that Electrosonic S-COM cable is used.

1.
Check that the fascia plate has been supplied with two fixing screws.
2.
Check that the two spring clips are fitted to the top and bottom flanges
of the control unit.
3.
Connect the control unit using the procedure on page 10 and set the
configuration switches as required (see page 12).
4.
Carefully insert the control unit into the wall back-box, ensuring that
the connecting cables do not become trapped.
5.
Secure the unit using the two captive screws on either side, ensuring
that the front face of the unit remains parallel with the wall surface.
NOTE
6.

The front face of the control unit must be slightly recessed into the
wall box to ensure that the fascia is a tight fit. The spring clips will
prevent the unit from moving in too far.
Locate the fascia plate over the push-buttons, ensuring that any
legends on the plate are the correct way up. Then secure the plate to
the control unit with the two screws provided.

NOTE
Concealed-fixing fascia plates are available to special order only.
1.
Check that the fascia plate has been supplied with the following:
2 x Retaining grommets,1 x Locating plate,
4 x Countersunk bolts,4 x Nuts.
2.
Prise off and discard the two spring clips from the control unit flange.
3.
Insert the two retaining grommets into the front flange of the control
unit; these are push-fitted from the front face.
4.
Fit the locating plate behind the control unit flange with the ‘cranked’
fixing tabs positioned towards the wall. Then, secure the plate using
the four nuts and bolts, ensuring that the nuts are on the wall side.
5.
Connect the control unit using the procedure on page 10 and set the
configuration switches as required (see page 12).
6.
Carefully insert the control unit into the wall back-box. Ensure that the
connecting cables do not become trapped. Then secure the unit
using the two captive screws on either side.
7.
Line-up the two locating pins on the back of the fascia plate with the
retaining grommets, ensuring that any legends on the plate are the
correct way up. Then push the plate inwards until fully against the
wall surface.

1.
Strip back the overall sleeving of the input and output cables
by about 40mm.
2.
Strip the insulation on each power conductor back by 6mm, and twist
the core strands together.
3.
Fold back the end of the data cable screen(s) by about 25mm to reveal
the two data conductors and screen drain wire. The screen will be
used to make electrical contact with the cable clamp.

Insert each power cable and data conductor into the appropriate
terminal (see Fig.1-3) and tighten the terminal screw.
7.
Finally, secure the data cables (with their screens) in the cable clamp
next to the terminal block using the metal plate and self-tapping
screws provided; the power cables are to be left unsecured.

IMPORTANT NOTES:
The electrical continuity of the data cable screen must be maintained
throughout the length of the data highway. The ‘screen’ and ‘power ground’
must not be connected together.
To preserve the system’s EMC screening, the unscreened portions of data
conductors must be kept as short as possible (typically no more than 10mm).

SETTING THE CONFIGURATION SWITCHES
A bank of 12 DIL slide switches is located on the rear of the control unit
and these are used to set the SCENECOMMANDER system address, group
address and data line termination (see Fig.2-4). When supplied, all of the
switches are set to the ‘OFF ’ position (as illustrated).
Data Line Termination
If the SCENECOMMANDER is at the end of the data highway, a
termination resistor must be placed across the data lines by setting
switch 4 (of the block of four) to the ‘ON ’ position.
For all other units along the data highway, this switch must be ‘ OFF ’.
For details of setting the base and offset address, refer to the
SCENECOMMANDER User Guide (ref. EPD02131). For the basic
installation, it is only necessary to set the data line termination.

FASCIA PLATE REMOVAL
To remove a screw-fitting fascia plate (e.g. to gain access to the
programming socket) simply undo the two securing screws and lift the
plate away.
To remove a concealed-fixing fascia plate, insert the blade of a small
flat-bladed screwdriver into the notches on the lower edge of the plate
(Fig.2-5), and carefully prise the plate away from the control unit.
