4.10.8 Audible Supplies; Table 13 – St950 Elv Detector Transformers - Siemens ST950 Handbook

Due to the inrush current drawn by the Detector Supply Transformers, there
are limitations to the number of 50VA and 160VA transformers that can be
fitted. Do not exceed the quantities in the table below: e.g. if fitting 2 x
160VA transformers, then a maximum of 3 x 50VA transformers can also be
fitted

4.10.8 Audible Supplies

The ELV Audible Driver Module derives the power to drive the Audible sounders
directly from the green drive of the LSLS card.
Audible sounders used must operate correctly over the voltage range 10 to 24V DC.
The audible units recommended and supplied by Siemens, which meet this
requirement, are 667/4/04785/000:
Highland Electronics type SC628P (was Sonalert Mallory SC628P)
Roxborough type SPCI535A4
Askari (Tone 22 – variable volume)...
4.10.9 ELV Tactile Units
The following tactile units are recommended.
667/1/17390/248
BIC B0302
Where lamp monitoring of the pedestrian green signals is not required, the tactile unit is
driven directly from the pedestrian green LSLS output.
Where lamp monitoring of the pedestrian green signals is required, the tactile units
must be driven from an additional green LSLS output assigned to the same pedestrian
phase green and lamp monitoring of that addition LSLS output should then be disabled.
