1.2 Positioning the Sentinel
1.2.1 In-Bay Applications
For in-bay automatics and other applications where the Sentinel is installed at the wash entrance, it should
be placed 10’-14’ from the wash to ensure the proper timing and flow of customers.
For curb mount applications, the front surface of the Sentinel should be even with the edge of the curb. To
achieve this dimension, the base frame should be installed so its leading edge is 7 in. from the edge of the
curb.
1.2.2 Express Wash Applications
Express Exterior sites should be designed to provide 9 ft. wide traffic lanes at the Sentinels. The traffic
control (or barrier) gate should be located approximately 10 ft. from the center of the Sentinel and an
underground vehicle detection loop is required under the gate arm. In some cases, it may be desirable to
install a 2
nd loop between the gate and tunnel entrance (referred to as the merge loop) to properly manage
the vehicle queue.
If the Unitec Reach Free ID (RFID) option is included, the RF Antenna should be located adjacent to the
Sentinel. Figure 1 provides guidelines for the design of an Express lane with the Sentinel, gate and RFID
(antenna) option. Refer to the installation instructions provided with the gate and RFID option for guidance
in installing these devices.
