5.1 INSTALLATION CHECK LIST

The checklist on the following pages should be used to install the unit together with the

Instation computer printout for the equipment to be monitored. For further guidance on

each step refer to the appropriate section in the REFERENCE column. ‘WORKS

ORDER’ indicates that the relevant Works Order or Works Specification should be

consulted.

Installation techniques are shown on drawing 667/GA/26577/000 in Appendix B.

For GSM OMCU installation, see also 667/GA/32600/002 in Appendix B.

The checklist should be followed in sequence unless a particular step is not required.

Refer to the relevant column (OMCU, C/P [Car Park Count O/S], BUS [Processor],

MOVA, VC [Vehicle Classifier], UTMC OTU and UTMC VMS) to determine whether the

step applies to the application or applications that are required. For example, if the unit

is to perform both OMCU and Bus Processor facilities, then all activities in both the

‘OMCU’ and ‘BUS’ columns should be undertaken.
