4.17 Audible Supply Kit

To provide drive for audible indicators an Audible Driver Kit of parts can be ordered. The

audible driver is not contained within the Outercase chosen form Table 4 and therefore

should be ordered separately. Please consult the parts listing. With Reference to Figure 79,

the module is powered from the green phase of the relevant pedestrian phase output of the

LSLS card. A 12V DC output drives the appropriate audible unit. The module can be

connected to an I/O card to allow operation to be inhibited and to allow switching between

Loud and Quiet sound levels.

Output connection for the Audible units can be taken from the appropriate Loud/Quiet

connections, indicated in Figure 79. The appropriate Power Present (PP) LED on the

module illuminates when the Loud/Quite audible is being driven. Each Audible Driver Module

can drive up to 8 audible units. It is recommended that all audible units connected to an

Audible Driver Module are the same type. If there is a requirement to switch between loud

and quite a minor modification to the Audible Driver Module is necessary. Full detail of these

additional requirements should be sought from the ST950ELV General Handbook.
