Operation - Timeguard DS1 Instructions For Installation And Use Manual

If only one DSS is required then connect the mains supply live (L) to L
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 of the second DSS is connected to
IN
L of the third and L of the third to L (mains supply live) and so
MASTER IN
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
4
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
IN
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
Switch 2
Cable System to provide continuity for the SL connection.
