3. Installation of two GE Model 24x/250 readers back-to-back.
When installing two readers back-to-back on a wall that will separate
the two readers by four inches (101.60 mm) or less, a metal plate (for
example: Reader isolation plate, metal wall) must be placed between
the readers. To obtain the maximum read range, mount each GE
Model 24x/250 reader onto one or more Isolation Spacers.
Note: Two readers can simultaneously read the same badge or tag if the
distance between the two readers is less than four inches (101.60 mm),
back-to-back.
