Installation of the HID MaxiProx Reader
Install the MaxiProx reader on a gooseneck pedestal or stanchion. HID recommends
using the Falcon S1R1235 stanchion. Because the stanchion is metal, use the Falcon
MC5375-1CR MaxiProx reader acrylic spacer kit to buffer the reader from metal. The
MaxiProx reader and stanchion should be installed far enough back from the vehicle lane
so that vehicles driving by the reader will not damage it by striking it with side mirrors,
bumpers, etc.
Care should be taken when setting up control lanes that vehicles entering can
communicate with the ENTRY reader but will not pass through the read range zone of
the EXIT reader. The inverse is also true. If you have a pre-existing installation where
this is occurring, contact your controller manufacturer to setup a delay time for “same
tag” reads on multiple readers.
Refer to the installation instructions provided for further guidelines on using and
installing the MaxiProx reader.
End-User Instructions for the HID ProxPass Tag
The vehicle must be positioned so that the ProxPass tag enters the read zone as the
vehicle approaches the MaxiProx reader. This may require the driver to slow or even stop
completely in order for the tag to be read. It may be helpful to create lane controls to
stage vehicles in the proper position for effective tag detection.
Other Considerations When Using the ProxPass Tag
Loop detectors may cause interference with MaxiProx readers and cause reduced read
ranges. If this occurs, first consult the manufacturer of the loop detector to see if the
frequency can be adjusted. HID utilizes 125khz to excite and transfer data. If the loop
detector can be tuned, try to maximize the difference between the loop frequency and the
HID reader frequency.
The average read range of the ProxPass tag (with the MaxiProx reader) is six feet. The
maximum read range is up to eight feet. This should be considered when choosing a
parking space. If you park within the read range of the MaxiProx reader, the ProxPass tag
will continually try to communicate with it. This will drain the ProxPass batteries in a
short period of time.
The ProxPass tags will try to intercommunicate, and are shipped in special packaging to
avoid this. Once they are removed from the shipping materials and activated, they should
be kept at least six inches apart. This distance should not cause problems with vehicles
parked close together.
The batteries inside the ProxPass tag are not replaceable. When the battery life has
expired, the tag needs to be replaced.
