Installation Prerequisites
•
Ensure there is a provision for a ground circuit. The Card Access System assembly must be grounded by a qualified
electrician. An improperly grounded unit can result in equipment malfunction and void the warranty.
•
Use the latest Card Access System controller firmware. Mircom periodically updates panel firmware and Configurator
Software to add features and correct any minor inconsistencies. For information about the latest firmware or software
visit the 'Manuals and Downloads' section of the Mircom website at www.mircom.com.
