DS1/DSS – Instructions for
Installation and Use
If you have a DS2 please refer to
separate instructions on page 10.
Fig 2a – Rear of DS1
Fig 2b – Rear of DSS
1. General.
The DS1 is a time delay switch with an illuminated push button, which
replaces a standard single gang plate switch on a box 16mm deep. The
illumination guides the user to the push button and once this is pressed
the lights under control are switched on for a period from approximately
10 seconds to approximately 10 minutes adjustable by internal
potentiometer.
For situations requiring two-way and intermediate switching DSS’s can be
used in conjunction with a single DS1. Section 5 shows how these can be
used in retrofit without wiring modifications and section 2b shows how
they should be wired in new installations.
2a. Installation (Replacement of Single
ON/OFF Switches Only).
FOR INSTALLATION OF DS1 & DSS’s IN 2 WAY AND
INTERMEDIATE SWITCHING CONFIGURATIONS – SEE SECTION 5.
IF IN DOUBT CONSULT AN ELECTRICIAN. SWITCH OFF MAINS
ELECTRICITY.
Set the delay time adjuster on the DS1 to minimum (fully anticlockwise –
see fig 2a) to enable initial testing during commissioning.
Remove the existing light switch and transfer the two wires to the DS1
connecting them to terminals L and SL in either position. If two wires
were connected to either terminal on the original switch they must be kept
together and connected to either L or SL on the DS1.
Do not disturb any earthing wire connected to the wallbox terminal.
Ensure both terminals are tight before screwing the two plate fixing
screws supplied home sufficiently to locate the DS1 securely to the wall
box. Turn ON the mains supply.
2b. New Installation of a DS1 and Up to
25 DSS’s..
In a new installation the DS1 and DSS’s can be wired to give control of a
single lamp load by any of the switches.
This is shown in fig 3.

If only one DSS is required then connect the mains supply live (L) to L
IN
on the DSS and leave the SLAVE connection formerly going to the second
DSS open circuit.
Further DSS’s can be added by copying the circuit connections shown in
Fig 3 between the two DSS’s. The L
IN of the second DSS is connected to
L
MASTER of the third and L
IN of the third to L (mains supply live) and so
on for further DSS’s.
3. Commissioning.
Press the push button and the light(s) under control should come ON for
approximately 10 seconds. During this time the neon behind the push
button switches OFF. If the lamps under control are fluorescent they will
not switch ON immediately and the light intensity may be reduced
initially. If there are DSS’s installed as well repeat this test at each switch.
Having established that the DS1 and any DSS’s are working correctly the
mains supply should be turned OFF and the two fixing screws removed
from the unit. The DS1 can then be pulled away from the wall to enable
access to the delay time adjuster (see fig 2a). The delay time can then be
set to the required level and the DS1 fixed to the wall using the two fixing
screws. The push-in screw covers can now be fitted if required.
The mains supply should be turned ON and the push button pressed to
ensure the delay time is correct.
4. Operation.
Whenever light is required press the closest push button and the light(s)
under control will remain ON for the set delay time.
5. Replacing 2 Way and Intermediate
Switches.
This involves wire identification and tracing. Switch installation should
be left to a competent electrician who will be able to relate the circuit
diagrams shown in figs 4 to 11 to the practical installation.
There are two main ways of achieving 2 way switching – Strapping Cable
and Remote Live Access. The circuits for these are shown in figs 4 and 5.
They are shown with a single intermediate switch giving 3 way switching.
Further intermediate switches can be added.
A DS1 and two DSS’s can be used to replace these switches for both
wiring systems to give time delayed momentary switching at all three
switch locations. The DS1 should not be located at a former intermediate
switch location. The circuits for both wiring systems with the replacement
switches are shown in figs 6 and 7. No wiring alterations are required but
to establish which wires are connected to which terminals the wires must
be identified and traced. An in-line connector is required for the Strapping
Cable System to provide continuity for the SL connection.

Further DSS’s can be added to replace any further intermediate switches
in the system.
If there are no intermediate switches (2 way switching) the before and
after connections for both systems are shown in figs 8 to 11. Note that an
in-line connector is required for the Strapping Cable System to provide
continuity for the SL connection.

DS2 – Instructions for
Installation and Use
If you have a DS1 working alone or
with one or more DSS’s please refer
to separate instructions on page 1.
1. General.
The DS2 is a time delay switch with an illuminated push button, which
fits on a standard single gang wall box 16mm deep. It requires a neutral
connection and provides delay times between 10 seconds and 2 hours
adjustable by internal potentiometer and range switches. It can be used to
control lamps and other appliances within the limits set out in the
specifications section.
Several DS2’s can be wired in parallel to control a single load but the DS2
cannot be used in conjunction with DSS’s.

2. Installation.
IF IN DOUBT CONSULT AN ELECTRICIAN.
SWITCH OFF MAINS ELECTRICITY.
Set the switch position to 1 ON, 2 OFF and the delay time adjuster to
minimum (fully anticlockwise – see fig 2) to enable initial testing during
commissioning.
Connect the three wires to the appropriate terminals.
Mains Live – L
Switch Live – SL (to load)
Neutral – N
If two wires were connected to any terminal on the original switch they
must be kept together and connected to the appropriate terminal on
the DS2.
Make sure that the wallbox is earthed if it is metal. Ensure that all three terminals
are tight before screwing the two plate fixing screws supplied home sufficiently to
locate the DS2 securely to the wall box. Turn ON the mains supply.
If further DS2’s are required to control the same load they must have all
corresponding terminals wired in parallel with these on the first DS2.
3. Commissioning.
Press the push button and the light(s)/appliance(s) under control should come ON
for approximately 3 seconds. During this time the neon behind the push button
switches off. If the load under control is low energy or fluorescent lamps they will
not switch ON immediately and the light intensity may be reduced initially.
Having established that the DS2 is working correctly the mains supply
should be turned OFF and the two fixing screws removed from the unit.
The DS2 can then be pulled away from the wall to enable access to the
delay time adjuster and 2 gang range switch (see fig 2). The delay time can
then be set to the required level by setting the 2 gang range switch
according to table 1 and then adjusting the delay time adjuster. The DS2
can then be fixed to the wall again using the two fixing screws. The push-
in screw covers can now be fitted if required.
The mains supply should be turned ON and the push button pressed to
ensure the delay time is correct.
