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 anti-
clockwise – 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 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.
