Darrell,
I agree that the swing arm extension design modification to theIntellistrobe system you describe does not require any testing and theFHWA acceptance is still valid with this design modification.....Matt

IntelliStrobe Safety Systems W1-AG Setup and Operation 8
How to set up an IntelliStrobe W1-AG
Always set up work site according to MUTCD, state, or local government rule, using signage, channeling, and barriers applicable to work site conditions.
One worker can easily setup and operate
the safety system.

Proper Work Zone Setup using AFADs
This slide illustrates the proper setup of the work zone. The hoses should have about an 18-24 inch separation, with the red hoses always positioned to the outside of the work zone.
Red Hoseoutside
BlueHosesInsideThe use of the four or
more channelizing devices shown here as (optional) is strongly recommended. They help establish the “lane”which is controlled by the AFAD.

Gate arm Sonic Sensors IntelliStrobe AFADs equipped with a gate arm, have a Safety system to prevent the arm from descending on a vehicle. This is a Sonic Sensor system, internal to the system.If the FC401-1 transceiver ever has a single Red Ledflashing, it indicates that device’s sonic sensor has activated and prevented contact with something.
Press red button to reset system
Flashing red LED=gate arm sensor hasfunctioned
Press the red button to restore the system to normal operation.

Positioning the Gate Arm Stripes
Ensure that the red and white stripes extend from the upper right to the lower left when viewed by traffic entering the zone.
Stripes extend from upper left to the lower right when viewed by traffic approaching from the opposite end of the work zone
IntelliStrobe Safety Systems W1-AG Setup and Operation 13
Operating the Transceiver Control
After both devices are turned on, press the red button on the transceiver and hold until all LEDs flash once, this is usually about 3 seconds.
Selected device displays yellow light and raises it’s gate arm
Hold Redto turn on
Now select either green numbered button to allow traffic to enter the work zone. This will turn the selected device to yellowyellow and raise it’s gate arm. When finished with the system for the day, press and hold the red button until all LEDs flash two times, usually about 4 seconds to turn it off.
Hold Red to turn off

CONFLICT MONITOR SAFETY
•The IntelliStrobe AFADs have a conflict monitor built into their systems.
•It is impossible for both ends of the work zone to display yellowyellow.
•You must always position both devices in the red condition, prior to putting either device in the yellowyellow condition.
IntelliStrobe Safety Systems W1-AG Setup and Operation 15
Single Device Usage:Bypassing the Conflict Monitor
If for any reason only one device is needed, that device must be in “single” mode in order for it to go to a RED condition. If it is in the “dual” mode, it will ask for a RED confirmation from a nonexistent device; therefore, preventing it from ever displaying YELLOW.
IntelliStrobe Safety Systems W1-AG Setup and Operation 16
Transceiver Control OperationWhen you have the number 1 device on yellowyellow and want to position the number 2 device on yellowyellow, you must 1. Always press the red reset button first,
3. Then press the number 2 greengreen button to turn number 2 to yellowyellow, and raise it’s gate arm.
2. Allow the the number 1 device to return to red and it’s gate arm to return to the lowered position,

Emergency: Alert the work crew WITH FLAGGERS:
This safety procedure requires:
1. Jump out of harms way to avoid impact,2. Tell other flagger with walkietalkie to stop opposing traffic
3. Alert the workers to the impending danger with noisemaker
This can very easily take 10 seconds to accomplish—how far can a car travel into your work zone at only 20 miles per hour?

IntelliStrobe Safety Systems W1-AG Setup and Operation 20
Emergency Alert Function: Motorist Violation
If either device is on red, and a motorist decides not to stop, therefore violating the red condition,the motorist’s initial contact with the red hose will cause:
•the 130 decibel siren on that device to immediately sound,
•the other device to turn red, and
•the other device’s gate arm to lower to the horizontal--stop-- position.

Emergency Alert Function:Safety Features
This safety sequence will:
•Alert the workers to the impending danger,
• Direct their attention to the end of the work zone where the danger is present,
•Stop the opposing traffic, and
•Almost always Stop the motorist causing the danger.

Emergency Alert Function:How to Stop the Siren
Pressing the red reset button will stop the siren and return the managing of traffic to the operator, when he or she determines the area is once again safe.

Emergency Alert Function:Sounding the Safety Alarm
If for any reason, the operator wishes to sound the safety alarm and place both devices in the red condition, the yellowyellow button on the transceiver is pressed.
