Pi-Lit® Remote Control Unit

PURCHASING

The Pi-Lit® Remote Control Unit utilizes the same technology and radio as our sequential radio-linked lamps. There is a remote control unit available for all of our products.  However, the ICS Remote Control will not operate the Barricade or Sunflower lamps.  Nor will the Barriade of Sunflower operate a ICS flare.  This is by design.  A Barricade or Sunflower Remote control will operate all of the products in this product line. The remote control unit allows the operator to perform all functions on our lamps from the safety of their vehicle, or standing off  the road or on an overpass up to 330 meters (1000 feet) from the lamps.

The remote control unit is primarily used for our sequential barricade and cone-top warning lamp where the lights could be out for months at a time. This allows for a safer/more convenient way of changing the parameters on the lamps at any given time. 

Since the ICS™ Sequential Flare and Landing Zone Kit are more for short term quick deployments, the remote control is not frequently needed. However, there are times or applications where you do need the remote control unit for the flares and we have it readily available for you. 

The Pi-Lit® Remote Control Unit comes with 2 AA-Alkaline batteries and Instructions.

Yes we supply a free remote control unit with any purchase of 50 Sequential Barricades or Sequential “SunFlower”™ Cone-Top Warning Lamps. 

We have distributors world-wide.  Where we do not have a distributor close by, we can work with you directly.  Call us 24×7 to discuss color options, battery choice, and general information.  +1(949)415-9411

SETUP AND USE

Turning on and using the remote control unit

The remote control unit does not have an on/off button. Any button press will turn it on.  After a period of no activity the remote control unit will go into a deep sleep state until the next button press wakes it back up. 

You do not need line of sight for the remote to control the warning lamps. The remote uses the same technology to communicate with the lamps. As long as you are in range of a single lamp, the message will propagate to the other lamps down or up the string.  

Battery Status, Changing Batteries, Charging Flares

Like all of Pi-Lit® Sequential Warning Lamps, the remote control has the ability to interrogate the status of the batteries. No more random changing of batteries. 

To do so, press and hold for 3-seconds the “π” button. The LEDs under the pattern section will light up. If all 5 LEDs turn on then the batteries are full. As the battery begins to deplete, less LEDs under the pattern section will glow. We suggest changing batteries when two LEDs are left on.

5 Green LEDs = 100-80% (Full)
4 Green LEDs = 80-60%
3 Green LEDs = 60-30%
2 Green LEDs = 30-15% (Low) (change or charge batteries)
1 Green LEDs = 15-0% (Dead) (change or charge batteries)

Group Changing

Both our ICS flares and construction sequential lamps are available in 5 different “Groups” or frequencies.  This prevents cross talk when two or more strings of sequential lamps are placed in proximity (330 meters – 1000 feet). While you may specify which Group you prefer when order lamps, we typically will ship in Group 1 (of 1 through 5) for constructions lamps and Group 6 (of Group 6-10) of the ICS flare.

We refer to Groups 1 through 5 for the construction lamps, and Group 1 through 5 for the ICS flare, even though technically the flares are set on channels 6 through 10.

Now, that wouldn’t be nice, would it.  Of course we anticipated that you would want to change the Group frequency.  You convinced the Chief to be the first to purchase a set of flares and then the followers start to buy.  Sure enough, there will be a frequency conflict, or not.

With the flare off and not flashing, press both buttons with your thumbs for 3 seconds.  The flare will echo back with a small green LED the current Group number.  Then press the square Pi button to change to the Group of your choice. Once you have pressed and achieved the Group of choice, do nothing for 3 seconds and the flare will flash red to indicate that it has stored your new Group number.  Do this for each flare.

The red indicator LED comes on when it thinks that you are finished playing, and stores the current choice and goes back to sleep.  So, while you are pressing the square button, you can change your mind and choose another Group, or if you incorrectly press the button, you can correct it.  Just keeping pressing the square button to achieve your choice.  But if you hesitate too long, the red LED will come on and store the choice and put the flare into a sleep mode.  No problem.  Press the two buttons again and start over.

We have implemented a new quick and easy way to change the Group for your set of sequential flares. You can change the Group number on any number of lamps all at once.

  1. Turn on all the lamps you wish to change Group number on.
  2. Choose any flare. Using your thumbs, press and hold both buttons for 3 seconds (simultaneous). Don’t let go!
  3. The red indicator LED on the flare that you are handling will come on for 1-second. CONTINUE TO HOLD BOTH BUTTONS! This indicates that you are entering Group change mode.
  4. After the continued press of both buttons beyond when the red LED first came on, the red LED will stay lit and the same LED will light up on all the flares that are on and in range.  You can now release the buttons.
  5. In 5 seconds, all the red LEDs will go dark.  They are still on and listening for a command from the flare that you are handling. Now all the lamps are in Group change mode. You must wait for the red LED to turn off before proceeding to change the Group (below #6).
  6. Tap the square button to choose which Group you prefer. Each tap will increment the Group number.  Tap once for Group 1. Wait for the green LED indicator.  Tap again for Group 2 and wait for the green LED indicator. Tap again for Group 3. All the lamps will echo back the same Group number.  When you get to Group 5 and tap the square button again you will return to Group 1. IMPORTANT NOTE: You must make your Group incremental change within 5 seconds.  After 5 seconds the system will time out and you will have to start over.
  7. When you have chosen the Group you prefer, wait 5 seconds and all the lamps will flash the red indicator LED.  Then the green LED will flash to indicate the Group chosen. The lamps have now turned off and gone back into a well-deserved sleep.
  8. Congratulations!

 

One more note:  If you wish to change the Group number on a single flare you may do so.  Press and hold both buttons for 3-seconds until the red green LED flashes to indicate the current Group number.  Then press the square button to increment the Group number.  Once you are satisfied with your choice, do nothing for 3-seconds and the red LED will flash.  The Group number has been saved and the flare has turned off.

SPECIFICATIONS

Pi-Lit® technology operates in the I.S.M. 2.4Ghz frequency band. This spectrum of radio frequency is dedicated to low power devices designed for  use in the Industrial, Scientific, and Medical industries (I.S.M.).

Indeed.  All of our products utilize a “System on a Chip” (SoC) with microprocessor (computer) and radio transmitter and receiver all on a single silicon wafer.  This component is FCC compliant and our circuit design has been tested by an independent laboratory confirming that spurious signals and radio-frequency output energy fall within strict FCC guidelines, and that the device is immune from external radio-frequency “noise”.

The Pi-Lit® product line operates at 6.0 volts nominal. In fact, 4-alkaline cells (whether AA or D-cell) in series generates 6.4 volts with fresh batteries.

The rechargeable systems utilize lithium polymer battery technology with nominal voltage of 7.4 volts (8.4 volts with fresh charge).

In all of our systems the “smart” electronics (micro-controllers, multiplexers, and stuff like that) operate and 3.0 volts requiring a 3.0 volt regulator to maintain a constant 3.0 volts.  The LEDs operate at a higher voltage.  Lamp brightness (intensity) is controlled through Pulse Width Modulation (PWM), where the duty cycle (percentage of on-time to off-time) during a 1-millisecond flash is varied according to the battery voltage.  As the battery depletes, the duty cycle increases to maintain constant brightness.  This approach is much more efficient because it eliminates the need for large current-limiting resistors which convert electric current flow into heat.  What appears to the onlooker as a 200 millisecond flash is really too flashes each 1 millisecond long.  Your eye cannot resolve this rapid a flash, and it all blends together.  But by varying the duty cycle the intensity can be controlled.

In its current plastic housing the flares are rated at IP57. We are in process of designing a new injection molding tool that will improve its water and dust seal to meet IP67 or greater.

TROUBLESHOOTING

To reset your remote control unit simply take out the two AA alkaline batteries. Once the batteries are removed tap any button to discharge (reset) the remote control. Insert the batteries back in and the remote should begin its boot up sequence. 

If your ICS™ sequential flare is powered on and flashing out the top LEDs when it should be flashing out the side LEDs then this quick fix will resolve the issue. For both versions of the sequential flare (rechargeable and alkaline) you must reset the flare in order to unlock the top LEDs. To do so follow these instructions:

Alkaline – Simply remove the batteries in the flare. Once removed tap either the square button or round button to discharge the flare completely (reseting the flare). Install the batteries back into the flare.
Rechargeable – To reset a rechargeable flare, attached the flare to the carrying/charging case. Once attached plug the case into your vehicle or wall socket at your home or office. Once plugged in the flare indicator LED should turn red, showing the flare is currently charging. While its charging tap either the square or round button to discharge the flare completely (resetting the flare).  Once you have tap the button you may pull the flare off the case. The flare will flash its main LEDs and flash the green indicator LEDs for current battery state.

This bug has been resolved. Newly purchase flares will not have this issue.
