The FIREFLY AMR System is an automated meter reading system that collects meter reading data remotely and
wirelessly. This is accomplished using the Datamatic FIREFLY Meter Interface Unit that sends the radio signal to the
ROADRUNNER handheld receiver unit (walk-by) or the ROADRUNNER Mobile truck mounted receiver unit (drive-by)
or the Mesh Controller, Gateway.
The main benefits of using a wireless AMR system are:
• Increased speed of meter readings
• Increased accuracy of meter readings
• Safer meter reading procedure
After reviewing this training manual you should be able to perform the following functions:
• Install an electric FIREFLY
• Program an electric FIREFLY
• Set up and utilize all FIREFLY menu functions
• Read the FIREFLYs for billing
• Perform periodic audits and troubleshooting on FIREFLYs
Following are some basic rules on how to read “clock style” electric meter indexes. Each of the four or five dials on the
meter represents one digit of the present reading. The dials move both clockwise and counter-clockwise. When the hand
of one of the dials is between numbers, always take the smaller number. For example:
Residential Electric meter example
4 6 3 7 2
This reading would be 46372. To tell if a hand is past a number or not, look at the dial to the right. If the dial to the
right has passed zero, then the hand is pointing to the correct number. If the dial to the right has not passed zero, then use
the next smaller number.
To practice, go outside a home or business and record the readings for several days in a row. By subtracting yesterday's
reading from today's reading, you can get a feel for how much energy (kilowatt hours for electric) is used each day.
When a power company representative reads a meter, they do not set it back to zero. Therefore, the dials keep turning
until the next time the meter is read. By subtracting two consecutive readings, the amount of consumption is determined
for the month. Utilities check to confirm that the readings each month fall within an expected range. If a reading is
significantly lower or higher than expected, the meter reader can be alerted and confirm the reading is correct. This helps
ensure bills are accurate each month.
This reading is 00000. Cyclometer (or odometer) style indexes
are easier to read and can be found on both electric meters.
1. Remove the glass cover from the electric meter.
Remove the break-away brass tamper seal, if
equipped.
2. Remove the screws from the utility faceplate.
3. Remove the utility faceplate from the meter. Clean
the disc on old meters, if necessary.
4. Place marking template over meter disc, being sure to include one calibration
hole and any black painted stripe in the marking area.
Note: When painting the disc, make sure that any calibration holes that do not fall within the painted area will not be
positioned over the FIREFLY optics at the same time as the painted area.
5. Using the Datamatic D2311 paint marker, paint in the entire area of the template. Leave no empty spots within the
template area.
Note: If the meter disc is already painted, still place template over disc to ensure the entire area is covered. If not, paint in
additional area within template not already covered with paint.
6. If required for this meter type, add metal extensions to the meter.
7. Position the FIREFLY on top of the nameplate posts.
8. Mount the unit flush on top of the nameplate posts with the spacer and nameplate above it.
9. Thread the mounting screw through the faceplate, the nylon spacer and FIREFLY into the faceplate post holes.
10. While applying pressure perpendicular to the disc plane, tighten down screws into faceplate post holes.
11. Make sure FIREFLY is parallel with the meter disc; adjust if needed. Ensure the meter disc moves freely.
12. Attach fuse clips on FIREFLY wire ends to the meter 240 VAC terminal posts on the top of the meter. This is the
city’s side of the meter. Avoid placing clips next to lightening arrestors.
Note: Do not attach the fuse clips to any painted area on the meter posts.
13. Replace the glass cover on the meter, making sure the FIREFLY wires do not get pinched between the meter and the
cover.
14. Optional: Test meter and calibrate on a test bench.
15. Install the meter into the 240V socket on a house or business, being careful to not jar the meter to prevent loosening
the FIREFLY batteries.
Note: All work on Electric FIREFLYs needs to be done taking static grounding precautions. Failure to use a grounded
static mat and wrist strap when handling or retrofitting the FIREFLY to an electric meter could result in static discharge
damage to the electronics. Units found to be damaged in this manner will not be covered by Datamatic warranty. See
picture of static mat below:
Electrostatic Discharge (ESD) is the enemy of electronic devices. You should always take precautions to eliminate any
electrostatic charge from your body and clothing before touching any semiconductor device or card by using an
electrostatic wrist strap and/or rubber mat.
Static electricity can harm system boards. Perform installation at an ESD workstation and follow proper ESD precautions
to reduce the risk of damage to devices. Datamatic strongly encourages you to follow proper ESD procedure, which can
include wrist straps and smocks, when servicing equipment.
You can also take the following steps to prevent damage from electrostatic discharge (ESD):
• When unpacking a static-sensitive device from its shipping carton, do not remove the device’s anti-static packaging
material until you are ready to install the device. Just before unwrapping the anti-static packaging, be sure you are at
an ESD workstation or grounded.
• When transporting a sensitive device, first place it in an antistatic container or packaging.
• Handle all sensitive devices at an ESD workstation. If possible, use anti-static floor pads and workbench pads.
• Handle devices and boards with care. Don’t touch the devices or contacts on a board. Hold a board by its edges or by
Note: The FIREFLY requires 240VAC during programming to write settings to its memory.
1. Optional: Do the Meter Exchange Procedure. (F1 – D)
2. Power the meter with 240VAC (place the meter into the 240V socket).
3. Select Program FIREFLY from the FIREFLY Menu. (F5 – 2)
4. Select the addressing method by choosing #2. Serial Number.
5. Enter the 8-digit FIREFLY serial number located on the capacitor.
6. The ROADRUNNER begins initializing.
7. Select the meter brand you are installing the FIREFLY on. If the meter brand is not listed (but qualified by Datamatic)
use “Other” and type in brand name.
8. Enter the register number from meter (if not automatically populated with correct meter number from account).
9. Enter the visual reading for all 5 visible dials.
10. At the View Current Settings screen, check normal values entered on template. Press the ‘FNCTN’ and ‘End’ keys to
accept the values.
11. Select Save and Exit.
12. When the ROADRUNNER has returned to the route, take a Walk-Away Reading in Verify Read mode by
Interrogating the FIREFLY (press I).
13. Initial installation and programming of FIREFLY is complete.
Notes:
If you do not receive an RF message or signal for an extended period of time, one of two issues may have occurred:
• FIREFLY was mis-programmed (usually the Meter# being incorrect).
• The FIREFLY is not putting out an RF signal.
To exit the interrogation screen, press the ‘FNCTN’ and ‘End’ keys. You receive a screen to either select:
1. Skip Meter – then enter a Skip code.
2. Exit Install Read – takes you back to the route screen.
Select #2, Exit Install Read. Go back to Step #2 to reprogram the FIREFLY once more.
Troubleshooting Electric and FIREFLYs
Reports are generated from Installation and RV data that is sent to Datamatic. These reports are processed and then emailed back to the customers for review. These reports are used to identify which FIREFLYs need Troubleshooting.
Examples of FIREFLYs in need of Troubleshooting include No RF signal and Delta values outside of specified range.
