4.18 Tactile Unit
4.18.1 None Switched Tactiles
Non Switched tactiles are driven from the green man output of the appropriate pedestrian
phase and rotate whenever the pedestrian green is illuminated. Figure 80 illustrates the
necessary connections for non-switched tactiles. Refer to part listing.

4.18.2 Switched Tactiles
Switched tactiles are also driven from the green man output of the appropriate pedestrian
phase but can be activated when required by the I/O output. There are several mounting
options for the tactile controller module. When using tactiles, with integrated motor and drive
module, the assembly can be mounted in the pedestrian indicator. When using tactiles with
separate motor and drive module, the drive module can be mounted inside the nearest
Helios signal head (the recommended position for mounting the tactile controller is at the top
of the Amber aspect case – see Helios General Handbook 667/HB/30000/000). The drive
module can be mounted inside the traffic controller cabinet. Please refer to the ST950ELV
Handbook when installing tactiles in parallel. Separate returns must be used between I/O
card and tactiles.
