The Standard change machine retrofit kit replaces the obsolete components of the Standard 600, 500 and 200 change machines to enable the acceptance of new Canadian issued bill notes. The kit includes a new warranty covered circuit board, bill validator and power supply and cables designed to work with your existing coin hoppers. There are two kits available, SC-MAX manufactured by SEM for up to four hoppers and ARB-V19-SCM manufactured by Arbotronics Controls Systems for two hoppers. These kits can be self installed in less than an hour with out the requirement to remove your change machine from its location.
