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

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.

RedHoseoutside


Installing the Automatic Alarm-Safety Hose Assembly Attach the 2 rubber hoses to the quick couplers on the unit, being sure to attach the blue marked hose to the blue marked coupler,

Attach blue marked hose to blue marked coupler

Attach red marked hose to red marked coupler

Hoses ready to protect

and the red marked hose to the red coupler.


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


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.


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.


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?

555 FEET

A vehicle 555 feet into your work zone before your workersare fully alerted and can react to the potential danger!!!!


AUTOMATIC ALARM SYSTEM


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.

Safety alarm button Reset button

Both sirens will sound until the controller presses the red reset button.
