Introduction
System Integrity Recommendation – Surge Protector
WARNING: To prevent damage due to power network surges.
Safety Instructions
• Only qualified personnel should perform the installation.
• Follow all local electrical codes during installation.
• Although it is not necessary to disconnect power to the pole during installation,
one should always be aware of possible exposure to electrical elements.
• When working from heights, it is important to follow standard safety precautions
to avoid any danger of potential injury.
• Use appropriate work tools.
Installation Overview
Note: Read the Installation Guide in its entirety prior to beginning the installation
process.
The following is the NEMA installation process;
1. Physical installation of:
• NEMA in previously installed NEMA receptable.
2. Obtaining GPS coordinates of Allegro Photocell Repeater and either writing
electronically or recording manually.
Preparing for Installation
It is assumed that the luminaire cover has had a NEMA ANSI C136.10-2010 and
C136.41-2013 compliant receptacle installed.

Installation
To install an Allegro Photocell Repeater:
1. Prior to physically installing the Allegro Photocell Repeater
(a) Record the NEMA serial number and pole number, if any.
(b) Stand as close as possible to the pole and obtain GPS coordinates in decimal
degrees.
(c) Record the coordinates for the NEMA serial number.
(d) If you are sending the NEMA information entries one by one, please record the
information in a Microsoft® Excel spreadsheet and send to a Master Meter AMI
Technician.
2. Remove the existing photocell repeater by twisting counterclockwise, unlocking the
plug from the receptacle (see figure 1).
Figure 1

3. Align the tallest and widest prong (neutral) at the center of the photocell repeater plug
with the widest socket in the receptacle. Firmly insert the plug into the receptacle (see
figure 2).
Figure 2
WARNING: Attempting to insert the NEMA prongs into the wrong sockets in the
receptacle can damage the Allegro Photocell Repeater.
4. Twist the Allegro Photocell Repeater clockwise, until the Allegro Photocell Repeater
stops moving and is securely locked and the bottom of the NEMA is even with the top
of the receptacle (see figure 3 below).

5. Once the photocell repeater is installed, the light fixture will turn ON (light on). After
initial turn ON, the light fixture will run an ‘Auto Detection and Verification’ procedure
which identifies the lamp driver type and executes the following light on/off sequence:
• After approximately 25 seconds of being ON the light fixture will dim to about 5%, if
dimming is configured.
• After approximately 10 seconds, the light fixture will return to 100%.
• After approximately 7 seconds, the light fixture will turn OFF (light off).
• After approximately 11 seconds, the light fixture will return ON or to operational state
the internal photocell repeater schedule determines.

Activation
To activate the Allegro Photocell Repeater:
Record the serial number located on the side of the photocell repeater in Allegro
Technician NET. Determine what frequency you will be programming the unit for by
choosing the nearest base station (see figure 4).
Figure 4
1. Connect 2w-MMR to your laptop “USB Comm” (USB – Micro USB Cable) and switch
to ON.
2. Be sure to choose the correct “Comm Port” inside the software as shown in figure 5
below;
Figure 5

3. Once the 2w-MMR is connected you will see “Connected” in green letters on the lower
left corner of the application window (see figure 6).
Figure 6
4. Select the “Settings” icon (see figure 7).
Figure 7
5. In the “Settings” window ensure the following (see figure 8);
(1) Both Downlink and Uplink frequencies are set to default.
(2) Long Sync is selected within the Wake Up Sequence menu and 26 is entered
within the sec. entry field.
(3) The Save icon is selected.
Figure 8

8 | v0612.20F
6. In the “Operation Mode” window ensure the following (see figure 9);
(1) The last 7 digits of the Allegro Photocell Repeater’s serial number are entered into
the Single entry field.
(2) The + icon is selected.
(3) Once the + icon button has been selected, click the Get tab.
(4) Double-click the Get Comm Status command from the Get menu.
Figure 9
After the Get Comm Status command has been selected, a new .exe window will
appear (see figure 9.1).
Figure 9.1

7. At the bottom of Allegro Tech NET you will see a gray window, which shows the
current DN/UP Frequencies (see figure 10). The results show that the photocell
repeater is communicating! The repeater is now ready to be set to a new frequency.
Figure 10
Frequency
To set the Allegro Photocell Repeater to a new frequency:
The new frequency will be according to destination base station frequency. The below
example (see figure 11) shows how to change repeater frequencies for a specific city,
in this case City of XYZ.
Figure 11
1. Click on the “Settings” icon (see figure 11).
2. Ensure both the Downlink and Uplink frequencies as well as the Wake Up Sequence
are set to default on the 2w-MMR (see figure 12)
3. Select the Save icon (see figure 12).
Figure 12

10 | v0612.20F
4. Ensure the Allegro Photocell Repeater is marked as shown below (see figure 13).
Figure 13
5. In the “Operation Mode” window ensure the following (see figure 14).
(1) The Set tab is selected.
(2) The Set Uplink/Downlink Frequency is selected.
Figure 14
6. From the Setup Uplink/Downlink Frequency window (see figure 15) ensure the
following;
(1) The correct frequency (i.e. “City of XYZ”) is selected.
(2) The Play icon is selected.

The Allegro Photocell Repeater is now synced. Please send the following data to a
Master Meter AMI Technician to add to the system;
(1) Latitude and Longitude
(2) Serial Number of photocell repeater
(3) Address
(4) Height of repeater
(5) Frequency used
Once the above data has been reviewed and approved by a Master Meter AMI
Technician, you are free to begin magnetizing nearby registers or use Allegro Tech
NET to manually connect units in the field to the repeater(s).
