APPENDIX C – REQUEST FOR TECHNICAL SUPPORT FORM

For Technical support please fill in the form below and send it to your supplier. It is recommended that at
installation you complete this form as a record of the Installation. If there is a problem later on you can identify
what has changed.

For locating faults in “Nortech Inductive Loop Vehicle Detector” installations it is highly recommended that
you use the DU100 DIAGNOSTICS UNIT. Please refer to the DU100 user manual Doc. No. 895UM0001 for
details of how to operate the DU100.
