Light Requirements for the Primex Eco Clock
The Primex Eco Clock operates best with a minimum lighting level of 220 lux--a measure of light intensity--for a period of
eight hours per day five days per week. When installing the Primex Eco Clock, consider the intensity of light where you
would like to place the clock. As shown in Figure 1, the intensity of available light in most indoor environments varies
widely. To identify the optimal location for the clock, use a light meter before hanging the Primex Eco Clock.
NOTE: Primex Wireless offers the Lux1010-B Digital Lux Meter (Part Number 14258). To order, contact Primex
Wireless Customer Service.

Primex Eco Clock Operation
The Primex Eco Clock can be installed anywhere indoors within range of the Primex Wireless 72MHz transmitter as long as
lighting is adequate. Under adequate lighting levels (220 lux or above), the clock’s photovoltaic cells, as shown in Figure
2, collect and store light energy to power the clock. When the Primex Eco Clock is started, the radio in the clock receives a
synchronization signal and sets the time automatically. When operating under optimal lighting, the Primex Eco Clock
synchronizes time once per day, at 10:01, 2:01 or 6:01 a.m. and p.m. and optically aligns its hands, if needed, daily at
midnight. With adequate light (above 150 lux), the second hand will operate normally with single-second stepped motion
(Model 14149 only).

Energy Conservation in Low Light Conditions
Each minute, the Primex Eco Clock samples the ambient light conditions. When light is insufficient for the photovoltaic
cells to support full functionality, the clock conserves energy. When conserving energy (the second hand on Model 14149
is not moving), the receiver is only turned on to synchronize time on Sundays at 2:01 a.m., and it suspends the second
hand’s sweep at 12 (Model 14149 only). When light is inadequate at midnight (the second hand on Model 14149 is not
moving), the clock aligns its hands only on Wednesdays at midnight, regardless of light conditions.
The Primex Eco Clock uses the light energy it harvests to power its operations, storing the excess in a rechargeable battery
(Primex Eco Clocks ship with this battery fully charged). If light conditions are not adequate to charge the rechargeable
battery, the Primex Eco Clock switches to the CR123 backup battery. Table 2Table 2shows how light intensity affects clock
operation and backup battery life.

INSTALL PRIMEX ECO CLOCK
CAUTION:Be careful not to damage the wires on the back of the clock when hanging or removing the clock.
Installation Overview
The Primex Eco Clock comes fully assembled and sets automatically with a few easy steps.
l You can start the Primex Eco Clock in a convenient central location such as a maintenance facility. However,
before hanging the Primex Eco Clock, verify at the clock’s final location that the clock has sufficient ambient
light and network signal strength for full operations.
l Before starting the Primex Eco Clock, be sure that the Primex Wireless transmitter is operating properly with
adequate building coverage.
l During the start procedure, the Primex Eco Clock receives a signal from the Primex Wireless transmitter. Primex
Wireless transmitters with external antennas broadcast for only 27 minutes each hour, from 39 minutes before
the hour to 6 minutes after the following hour. If you have a transmitter with an external antenna, follow these
guidelines to efficiently start your Primex Eco Clocks.
l Small quantity of Primex Eco Clocks: Start the clocks during the window in which the transmitter
is broadcasting.
l Large quantity of Primex Eco Clocks: Power cycle (unplug and plug in) the transmitter, causing it
to broadcast continuously for 8 hours, during which time you can start the clocks.
l Allow sufficient time to complete the full start procedure without interruption.
l Read the entire start procedure before beginning and refer to Figure 3

Installation Guidelines
l The Primex Eco Clock is for indoor use only.
l Depending on your security needs, you can choose among several options for hanging the Primex Eco Clock.
l The most secure method uses the Clock-lock feature, specially designed hangers precisely 9 in. apart at the top
and bottom. The Clock-lock feature is designed to prevent accidents if the clock is bumped, and they may
reduce theft by requiring a particular combination of moves to remove the clock.
l For a moderately secure method, use only the top Clock-lock feature.
l To avoid the Clock-lock feature altogether, use a finishing nail with no head angled at 45 degrees into the wall
in place of the top headed screws and anchors. The clock will then mount and can be removed like a standard
clock.
l Use the screws and anchors provided with the clock for installation. If you choose not to use the provided
screws and anchors, you can substitute a #6 screw. The screw must protrude from the wall .350 in. (.889cm).
Start the Primex Eco Clock
Before hanging the Primex Eco Clock, you start the clock and verify that it is receiving adequate ambient light and
transmitter signal in its final location. Below are procedures for these tasks.
1. From the back of the Primex Eco Clock, move the jumper connector from the two leftmost pins to the two right
most pins.
Figure 4: Move the Jumper
2. Install the CR-123 battery.
NOTE: Insert the battery ‘+’ end to ‘+’ end of the battery holder to achieve proper battery orientation.
The clock will turn on its radio receiver. The second hand will advance one step every five seconds until the time signal is
received (Model 14149 only). Once the time signal is received, the hands will automatically advance rapidly until the clock
reaches the correct time broadcast by the transmitter. During this process, the second hand may stop and start
periodically (Model 14149 only). If light conditions are adequate, the clock will operate normally.
Verify Adequate Light and Signal
The Primex Eco Clock requires adequate ambient light and transmitter signal. Before hanging the Primex Eco Clock in the
final installation location, verify that ambient light and transmitter signal are adequate in that area. Adequate ambient
light is necessary for full clock functionality with the clock’s photo cell supplying all energy requirements. Placing the
Primex Eco Clock in an area with adequate signal will reduce the amount of harvested energy used for powering the radio.

l Use a light meter to measure light levels in the location where you plan to hang the clock. Ambient light levels
of 220 lux or greater for 8 hours per day, 5 days per week are required for full functionality and best
performance. Primex Wireless offers the Lux1010-B Digital Lux Meter (Part Number 14258). To order, contact
Primex Wireless Customer Service.
l Ensure that the Primex Wireless transmitter is broadcasting during the time you are verifying the signal. Primex
Wireless transmitters with external antennas broadcast for only 27 minutes each hour, from 39 minutes before
the hour to 6 minutes after the following hour. If you have a transmitter with an external antenna, be sure to
perform this procedure during this time. Alternatively, you can power cycle the transmitter, causing it to
broadcast continuously for 8 hours while you complete this procedure.
Verify Adequate Ambient Light
l Use the light meter to take lux readings at the location where you plan to hang the light. Readings should be
above 220 lux to ensure full operation and best performance of the Primex Eco Clock.
l Consider the pattern of light at the location. The location must receive at least 220 lux of ambient light 8 hours
per day 5 days per week to ensure full operation and best performance of the Primex Eco Clock.
Verify Adequate Signal
l Hold the clock near the location where you plan to hang it.
l Push and IMMEDIATELY release the button. The clock will beep twice.
The clock will scan all channels looking for a transmitter signal. Once the clock finds a channel with a transmitter signal, a
series of beeps will sound from the clock. The clock will beep each time a valid time signal is received, which should be
once per second. The beeping will continue for one minute. If the clock is in a marginal signal area, it will beep once every
few seconds. No beeping means no signal is received.
Hang the Primex Eco Clock
1. Install hardware to hang the clock.
2. Hang the clock on the hardware.

MAINTAIN PRIMEX ECO CLOCK
The Primex Eco Clock requires very little maintenance. Below are procedures for maintenance.
Backup Battery
If the CR123 backup battery drains significantly, the second hand will double step when light is present (Model 14149
only). This indicates that the backup battery needs to be changed to ensure that the clock functions normally.
Backup Battery Guidelines
Under optimal operating conditions, the life of the Primex Eco Clock CR123 backup battery is ten years. Therefore, it is
important that you use fresh, superior-quality batteries, with an expiration date at least ten years past the installation date.
Completely removing power from the circuitry helps ensure that the clock cleanly starts after replacing the backup battery.
Since the Primex Eco Clock contains both a rechargeable battery and a backup battery, you must remove the jumper in
order to fully remove power from the circuitry.
Replace Backup Battery
1. Remove the clock from its location so that you can access the back of the clock. For additional information, see
"Remove the Primex Eco Clock" located on page 9.
2. Remove the CR123 backup battery.
3. Remove the jumper located on the two rightmost pins of the connector. For additional information, see "Start the
Primex Eco Clock" located on page 7.
4. Wait one minute.
5. Reinstall the jumper on the two rightmost pins.
6. Install the new CR123 backup battery.
NOTE: Insert the battery ‘+’ end to ‘+’ end of the battery holder to achieve proper battery orientation.
The clock will turn on the radio receiver and the second hand will advance one step every 5 seconds until time signal is
received (Model 14149 only). Once the time signal is received, the hands will advance rapidly until the clock reaches the
correct time broadcast by the transmitter. If light conditions are adequate, the clock will operate normally.
Check Hand Alignment
Perform this procedure only in the rare event that the hands are showing the wrong time.
1. Remove the clock from its location so that you can access the back of the clock. For additional information, see
"Remove the Primex Eco Clock" located on page 9.
2. Press and hold the button on the rear of the clock. The clock will beep 2 times. Continue to hold the button for 3
seconds until the clock beeps 2 times again. The hands will begin to move at an accelerated pace until the hands
align at the 12 o’clock position.
3. Press and hold the button again. The clock will beep 2 times. Continue to hold the button for 3 seconds until it
beeps 2 times again. The clock starts. If light conditions are adequate, the clock will operate normally.

FREQUENTLY ASKED QUESTIONS
Our buildings are shuttered for 3 months over the summer. How will this affect the Primex
Eco Clock?
The Primex Eco Clock is designed to handle this situation. When the Primex Eco Clock does not receive sufficient light for
full operations, it conserves energy by ceasing the second hand sweep (Model 14149 only) and less frequently
synchronizing time with the transmitter. Assuming that the clock was fully operational at the beginning of the summer,
the clock can operate with energy conservation over the summer. If the clock remains without adequate light for longer
than 3 months, it will begin to draw power from the backup battery.
Will the Primex Eco Clock work in most rooms?
While the Primex Eco Clock is suitable for many rooms, it may not be ideal for low light rooms such as cafeterias or
gymnasiums. Before planning to use the Primex Eco Clock, use a light meter to determine optimal locations for the clock.
When we turn the lights on, the Primex Eco Clock isn’t working. After a minute or two, the
clock begins to work. Why does the clock stop and start?
The Primex Eco Clock generates the energy it needs to work from the light in the room. Every minute, the clock checks the
light conditions to determine if it is receiving enough light for normal operations. When the lights are turned off, the clock
detects that it can’t generate enough energy, so it conserves energy by ceasing the sweep of the second hand (Model
14149 only). The clock is still working, so when you turn the lights on, the clock waits a minute and detects that the light is
sufficient, and again begins to move the second hand.
Will the clock run without the CR 123 battery?
No, the CR123 backup battery is necessary to operate the clock.
Will a brighter concentration of light (higher lux) charge the clock faster?
Yes, up to 600 lux, charging occurs at a slightly faster pace. Ideal conditions still require at least 220 lux for 8 hours per day
5 days per week.
