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.

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
3 4
wall box. Turn ON the mains supply.
2b. New Installation of a DS1
and Up to 10 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.
Fig 3
If only one DSS is required then connect the mains supply live (L) to
LIN 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 LIN of the second DSS
is connected to LMASTER of the third and LIN 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
4 5
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.
