3. Field Installation Checklist
☐
The Central unit and access control panel need a common ground.
☐
The Remote unit and card reader need a common ground.
☐
The top of each unit (where antennas are located) should point toward the sky.
☐
The Central and Remote units should be installed level relative to each other.
☐
There should be a direct line of sight between Central and Remote units (if there is no direct line of sight,
a Repeater unit is recommended).
☐
Both the Central and Remote units should be mounted high enough to avoid interference from obstacles
(vehicles, trains, buildings, trees, etc.).
☐
Metal mounting surfaces are not recommended. If use of a metal surface is unavoidable, space unit as far
from metal surface as possible using non-metal spacer.
☐
Enclosure locking screws (6-32 x 3/8) max torque rating 8.5 inch-pounds.
If troubleshooting is necessary, see manual.
