Cat No. DS1 2 Wire Slave Switch Cat No. DSS 3 Wire Electronic Time Delay Switch Cat No.
DS1/DSS – Instructions for Installation and Use If you have a DS2 please refer to separate instructions on page 10. 1 Tough flame retardant polycarbonate plate fits a standard single gang wall box 16mm deep. Illuminated push button. Optional push-in screw covers supplied Fig 1 – Front of DS1 and 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.
Delay time adjuster – centre scale gives approximately 5 minutes (linear scale).
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. 3 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 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.
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. 5 In keeping with BS schematic code wires shown in direct cross over (i.e. +) are not connected electrically.
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.
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. 10 Tough flame retardant polycarbonate plate fits a standard single gang wall box 16mm deep. Illuminated push button. Optional push-in screw covers supplied Fig 1 – Front of DS2 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.
Time range selector Delay time adjuster. Fig 2 – Rear of DS2 11 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 anti-clockwise – see fig 2) to enable initial testing during commissioning. Connect the three wires to the appropriate terminals.
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.
4. Operation. Whenever light or appliance operation is required press the push button and the light(s)/appliance(s) under control will remain ON for the set delay time. 5. Specifications. 13 i Conforms to Directives: 73/23/EEC & 89/336/EEC ii Permissible Loads: Filament lamps – 1.5kW Low voltage – 20 to 200W Heating – 2kW Inductive – 4A Motor – 1hp Not suitable for fluorescent or low energy lighting.
