Readers
Never mount readers close to high-voltage equipment. For convenient entry, the reader should be mounted at
a convenient height on the latch side of the door.
When mounting proximity readers for monitoring in and out activity at the same door, space the readers at a
distance greater than the combined radio signal read ranges. As an example, if the read range is 4 inches,
mount the two readers at a distance greater than 8 inches from each other.
For mounting readers to a metal surface, consult with the manufacturer's documentation.
