Regulatory Information
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s
authority to operate the equipment. Installation work must be done by a qualified person(s) in accordance with all
applicable local codes and standards.
Safety and Usage Precautions
The lantern's Battery Pack contains lead, lead compounds, and other compounds known to the State of
California to cause cancer and reproductive harm. Please handle with care and wash your hands
thoroughly after handling the Battery Pack.
Charge your lantern's Battery Pack periodically. Permanent damage and reduced capacity will result if
the Battery Pack is not correctly maintained. Refer to Battery Charging on page 8 for details.
Lanterns that have been stored may require a top-up charge before they are put into service. The most
accurate Battery Pack status reading is obtained when the lantern has been in a dark location and in Off
mode for at least 24 hours.
1. Introduction
The OL2A solar hazard marker is:
•Self-contained and solar-powered
•Easy-to-install and low-maintenance with a long-life LED
•Available in red, green, white, yellow and blue
•Easy-to-maintain with replaceable AA NiMH batteries
2-Hole Flange Mount
Pole Mount
Nominal range of a lantern depends on its effective intensity and environmental conditions. For details on how to
calculate range, contact your sales representative.
2. Applications
The OL2A is suitable for ground marking, way finding, perimeter marking and other applications where a hazard
marking light is required.
3. Installation
Year-round, unrestricted solar exposure is critical to long-term performance. Shade dramatically reduces the ability
of the light to charge its battery.
The OL2A has changeable mounts. Either ensure the 2-hole flange or pole mount is attached before lantern
installation.

Install the lantern:
1. If required, insert the reducing sleeve into the pole mount. Note that it aligns only one way.
2. Slide the lantern and sleeve over the pole; press down to ensure lantern is well seated.
3. Secure with the provided 3 screws; if required, drill 1/8 - 9/64 in. [3.2 - 3.6 mm] pilot holes and then install
the screws.
4. Operation
The solar panel charges the battery in daylight using the Energy Management System (EMS). The capacity of the
battery ensures that even with poor levels of sunlight over an extended period, the lantern has enough reserve
power to continue to perform reliably. Stored battery energy then powers the LED during the night.
The change from night-to-day or day-to-night is called a transition. To avoid false transitions and ensure stable
operation, the transition time is 2 minutes. For example, 2 minutes of darkness is needed for the lantern to switch to
night operation.
4.1 Programming
The OL2A is configured using the IR programmer. The lantern’s mating IR receiver is on an energy-saving sleep
cycle.
Press and hold for 2 seconds to awaken the IR receiver and begin communication with the lantern:
The lantern is now ready to accept programming. Note that the lantern will quickly flash after every key it receives.
All programming codes follow the same sequence:
3 quick flashes
Command accepted
2 slow flashes
Command rejected
The number symbol # represents 0 - 9. Commands can be rejected if they are unsupported, contain an incorrect
key sequence or have an effective intensity too high for the programmed flash code.

OL2A
USER MANUAL
©2019 Flash Technology, LLC Page 7
4.2 Setting the Flash
To set the flash pattern, enter its flash code using the IR programmer. See the Flash Codes on page 13 for details.
Example: Enter
For quick flash Q 1s 0.3 (flash code 129)
4.3 Setting the Intensity
The OL2A is programmed using effective intensity. Effective intensity is the brightness of a flashing light as
perceived by the human eye (as opposed to peak intensity, which is the actual intensity of a light during a flash).
Effective intensity is calculated using the following equation:
Effective Intensity (cd) =
Peak Intensity (cd) x Flash Duration (sec)
0.2 (sec) + Flash Duration (sec)
The OL2A makes this calculation automatically based on your programmed flash code and effective intensity
selected. Note that for a fixed/steady-burning light (code 001), effective intensity equals peak intensity. The range
of intensity codes are:
600 0.1-0.4 effective candela
601 1 effective candela
602 2 effective candela
6## Maximum values vary by flash code and LED color
Example: Enter
For intensity of 5 effective candela
Product performance varies by installation location. Contact your sales representative for further
details.
4.4 Turning On/Off
In “on” mode, the OL2A LED turns on at night and off during the day. The lantern charges in sunlight, but the LED
remains off when in “off” mode. When turned on again, the lantern activates at its last programmed settings (1
minute preview for daytime activations).
Option 1: Switched Models
Set the switch to on or off position
Option 2: IR Programmer
Point programmer at OL2A from a distance of one foot, press and hold for 4 seconds. The lantern LED will
brighten to on or fade to off to confirm your setting change.

OL2A
USER MANUAL

4.5 Checking Battery State of Charge (SOC)
Using the IR programmer, enter: or
Good Battery
SOC >70%
Charge Battery
SOC 14-70%
Low Battery
SOC ≤14%, LVD Active
If the battery is ≤14%, Low Voltage Disconnect (LVD) disables the LED and attempts to charge the battery to a
sustainable SOC. The LED is re-enabled once SOC is >75%.
4.6 Automatic Light Control (ALC)
During periods of sustained poor solar charging, Automatic Light Control (ALC) may decrease LED intensity based
on battery SOC and recent charging trends. When solar charging returns to a sustainable level, ALC increases
intensity back to the user setting. ALC may be disabled to keep the lantern at a constant intensity.
Enable ALC:
Disable ALC:
4.7 Battery Charging
The batteries are best charged inside the lantern. The OL2A can recharge 0 V or 0% SOC batteries back to 100%
SOC:
Summer sunlight 8-12 hours
Winter sunlight 18-36 hours
60 W incandescent lamp 15-36 hours
A commercial charger designed for 1.2 V AA batteries can also be used.
Do not use a battery charger with >370 mA charge rate. High charge rates will overheat the batteries
and cause internal damage.
Take care when charging using a lamp. Provide air circulation or a fan so that the lantern and batteries
do not exceed maximum temperature.
4.8 Battery Installation
The OL2A comes with 3x AA industrial-grade, high-temperature NiMH batteries. The OL2A will only operate with all
3x batteries installed correctly. The lantern remembers its settings even when the batteries are removed.
Other rechargeable AA NiMH batteries will not void your warranty. Shock, vibration, temperature and
optical performance may be limited.

OL2A
USER MANUAL

To install batteries:
1. Install batteries, noting their polarity.
2. Apply a thin coat of silicone lubricant to the large sealing o-ring.
3. Align top cover and assembly components; secure with the provided screws. Do not over tighten!
4.9 Storage
Turn the lantern off to store. In switched models, set the switch to the “off” position. To turn off using the IR
programmer, press and hold for 4 seconds.
If a lantern detects continuous darkness for 24 hours, like when it’s inside packaging for shipping or storage
purposes, it will disable the LED. Upon sensing light, it will enable the LED and continue normal operation.
Check the battery state of charge every 1-2 months and charge if required.
High-grade NiMH batteries shipped with the OL2A can be stored without any charging for up to 12 months
with no battery damage.
