1.5 Limitations of scope
This manual supplement provides an overview of the Flash Technology Road Holding Position Light with
wireless remote control.
This manual is supplemental to the general user manual and is not intended as a replacement. Consult the
general user manual for all other aspects of setup, operation, maintenance and troubleshooting.
This manual supplement provides rudimentary information for the Flash Technology aviation products
wireless Handheld Controller as it applies to the Road Holding Position Light only. Consult the Handheld
Controller manual for all other aspects of operation, maintenance and troubleshooting.
2.0 Theory of operation
The Road Holding Position Light is a solar-powered vehicle traffic flashing beacon system designed to provide
continuous 24-hour visual warning of mandatory roadway stop points and hazards. The beacon provides an on-off
flash pattern compliant with U.S. Federal Highways Administration, Manual on Uniform Traffic Control Devices
(MUTCD). The beacon also complies with the Institute of Transportation Engineers, Vehicle Traffic Control Signal
Heads (VTCSH) requirement for beam shape and chromaticity.
Note:
This system has been factory-configured to meet the VTCSH requirement for light output intensity: 365 candelas
The Road Holding Position Light is designed to operate continuously 24-hour per day. The product described
herein has been fitted with a 900 MHz radio receiver, which can provide on-off control of the system or temporary
timed 15-minute on cycles. See section 5.0 of this document for a table describing wireless control states and
operational modes.
3.0 Product Set-up
Please refer to the user manual for complete product set-up and product warnings
3.1 Antenna Installation
The control cabinet has been furnished with a replaceable whip style antenna.
Locate the antenna inside the cabinet and install it on the exterior of the control cabinet
as shown.

3.2 Mechanical Arrangement and Mounting
Note:
Consult the product user manual for an overview of mechanical components and general guidelines on system
mounting and electrical connectivity.
Note:
For wireless operation, line-of-sight is required between the Handheld Controller and the receiving antenna on the
system cabinet. The final physical arrangement of the control cabinet, solar panel, beacons and signage should not
impede line-of-sight between the location of the Handheld Controller and receiving systems.
Failure to provide line-of-sight between transmitting and receiving antennas may result in
unreliable system control
4.0 Product Configuration
This product has been configured for wireless on-demand activation, however, the product can also be operated
manually and can be configured to work autonomously 24 hours per day.
4.1 Wireless Control
For wireless control, the system will need to be configured as an R829 product. See user manual excerpt below:
Note:
Please consult the product user manual for instructions for using the on-board user interface (OBUI) and the
complete list of user programmable settings.
Figure 2. OBUI Detail
4.1.1 Grouping
The system can be assigned to one of 8 individual groups or “channels” on the Handheld Controller.
Please consult the appendix of the Handheld Controller manual for the location of the grouping button and the
following manual for complete information on assigning products to individual groups for wireless control
Note:
This product has been factory-set to respond to group #1 as a default.

R247-G with Wireless Control
4.2 Non-Wireless Control
For non-wireless 24-7 operation, see user manual excerpt below for configuration:
Figure 3. OBUI Detail
Note:
When the system is configured for non-wireless 24-hour continuous operation, the system will no longer respond to
commands sent by the wireless controller.
4.3 Beacon Intensity Settings
This product has been sized and configured for sustainable 24-hour operation at ITE intensity for RED LED traffic
beacons –365 candelas (Current setting of 220mA on the OBUI).
Note:
If higher intensities are required either for 24-hour or temporary system activations, please consult Flash
Technology prior to making intensity adjustments.
Increasing beacon output intensity may result in either unsustainable operation or a
reduction in usable battery life.
5.0 System Activation
5.1 Wireless Control
Please consult the Handheld Controller user manual for complete instructions regarding the use of the wireless
controller.
When configured for wireless operation and when operated with the Handheld Controller, the system can be used
in one of two ways:
Autonomous Mode: The system once activated will remain active with the beacons flashing indefinitely
until the system receives a “Lights Off” command from the Handheld Controller.
Temporary Mode: The system once activated will remain active with the beacons flashing for 15 minutes,
after which, the system will automatically turn the beacons off, unless, the system recieves a “Lights Off”
command from the Handheld Controller in the interim.

Note:
In wireless mode, when activated by the Handheld Controller, the system will flash the beacons at the intensity that
was preset through the system OBUI:
The Handheld Controller sends on/off commnands only.
Beacon intensity cannot be adjusted using the Handheld Controller
