4 – 4 Tactile Units and 1 Audible Driver Module (8 sounders) or 2 Tactile Units and 2
Audible Drivers (16 sounders) can be simultaneously driven from one LSLS output.
5 – Note that only product fitted with a clear ELV label
may be connected to the LSLS. Although the part numbers
of these products may not have changed, the internal
circuitry has - so on no account must a unit without the
relevant label be connected, otherwise spurious faults or
damage to the LSLS may result. Refer to the document
667/SU/46000/000 for information on the compatible
versions.
When signals are required to be lamp monitored, signal types must not be
mixed.
Specifically, when lamp monitoring Nearside Signals, it is not allowed to connect
Tactile Units or Audible Driver Modules in parallel to the Nearside Signals. In this case,
two or more LSLS Outputs must be specified for the pedestrian green aspect in the IC4
Configuration (Phase Type and Conditions page), with lamp monitoring disabled on the
outputs used by the Tactile Units or Audible Driver Modules.
When output types are NOT lamp monitored, it is permissible to mix output types.
Specifically, it is permissible to connect 2 Tactile Units, 2 Green Nearside Signals
(either AGD or Siemens) and one Audible Driver Module (8 sounders) in parallel across
one LSLS output.
