3.17 Audible Supply Kits

With reference to Figure 31 an additional mounting panel is provided on the left hand side of

the ST950 controller. This mounting panel will be utilised for mounting 48V (160VA) Wait

Drive Kits, 48V (50VA) Wait Drive Kits, 24V (160VA) Supply Kits and Audible Supply Kits.

The Audible Drive Kit contains a 48V (1500VA) transformer. The output from the transformer

is rectified and made available at a terminal block. The terminal block forms part of the

Audible kit and attached to the left hand side panel providing three outputs. If more than

three Audible outputs are required it is possible to order individual ancillary items (terminal

block etc) from the kit to provide an additional three outputs. If more than three additional

outputs are required an additional full kit must be ordered. The position of the transformer in

the Audible Supply kit is linked to the optimisation of the other supply kits positions. The

sequence of kit positioning is set out in paragraph 7.17. Drawing 667/GA/27006/000 details

the full wiring scheme. The Audible kit may occupy any spare position on the left hand

mounting plate however the rectifier component and terminal block should be mounted in the

same row as the transformer. Input Supply for the Audible Kit is provided from the pedestrian

green phase. Please note the negative input supply wire should not be connected to

the common input of any other equipment.
