Complete the following tests to confirm the normal operation of the MMR2 system.
2.3 Troubleshooting
Follow the procedure below to troubleshoot common MMR2 card reader issues.
Is the Card Reader reading cards?
• If no, what color is the LED on the reader?
• Solid red = lock out mode; will not accept any cards
• Solid amber = card accept mode (see below)
• Green = on schedule; open
• If the reader is amber and not reading cards, remove and wire the reader directly to the con-
troller and test.
• If the reader works at the controller, check your wires at the front and tone out cable for
continuity
• If the reader does not work at the controller, replace reader
• If you swipe the reader and reader works but door does not open, ensure the reader is wired
to the correct relay at the board. If it is, make sure power is being sent to door locking
devices.
