Page

The MaxiProx should not be mounted within six feet of any monitors (VDTs or CRTs) because the scan
frequencies of most monitors include frequencies that may interfere with the signal received from the
access control cards.

3.4 Transponder Types
Transponder Types
The type of transponder used affects the read range of the MaxiProx. The various styles of HID cards
and transponders use different types of antennas. The antenna type will determine the read range for
that type of transponder. The Vehicle ID tag provides the longest read range at 32-36 inches; the
ProxCard II is 24-29 inches. The IsoProx/DuoProx is 17-20 inches. The ProxKey reads at a distance of
15-17 inches.
Note
The above are recommended installation procedures. All local, state and national electrical codes have
precedence.
