Detailed Description
Lighting Controller. The analog controller for this application
includes several operational amplifier circuits: a battery charge controller
(to prevent battery overcharge), a battery low-voltage detector and disconnect
(to protect lead-acid batteries from premature death due to low voltage).
The gas discharge lamp (flourescent tube) is operated by a high-frequency
switch (also called an electronic ballast). Wiring options are available to
allow tie-in to auxiliary power, and for intensity increase in response to
pedestrian traffic. The Model 1205 Lighting Controller, presently available
from CI Solar Supplies Co., Chino, CA, is the basic unit used in TELEVOX kits.
(See separate specification sheet). |
Installation At a system voltage of 12VDC, UL approvals, the NEC,
and local government electrical wiring regulations are not applicable. Installation
consists of replacing the ceiling lighting panel with a new 12V lighting
panel , mounting the solar panel on a building roof, wood pole, or 2 inch
steel mast. The solar panel should be mounted out of the sight of vandals
yet clear to face the sun (due south in Northern Hemisphere). A wire pair
is run from the solar panel to the pedestal of the phone booth. Inside the
pedestal this new 12V cable is connected to the existing (120VAC) power cord
that runs to the lamp fixture. By using this existing power cord for 12VDC,
considerable time is saved over fishing a new cable through the narrow vertical
trough behind the phone mount.
Maintenance Considerations. Maintenance consists
of washing the solar panel (water pump sprayer is OK) to remove dust and bird
droppings about four times a year. The solar panels are guaranteed for 10
years. Lead-acid, sealed batteries will last about 4 years and should be
replaced on that schedule. (Why not use nickel-cadmium? Nickel-cadmium
batteries may last 10 years but their initial cost is 5 times more than the
lead-acid type, so the overall cost will be higher). The fluorescent lamp
bulb should be replaced with the battery. One way to accomplish this scheduled
maintenance would be to exchange the entire lighting unit, thus reducing
the field maintenance time. This schedule would also allow any improvements
to be incorporated into the controller electronics. All of the above maintenance
responsibilities can be assigned to a maintenance service company at a mutually
acceptable fee of $(* ) per unit per year. TELEVOX prefers a direct contract
for total installation and maintenance of Solar Lighting Kits; however, we
will cooperate with another service organization by providing service data
and repair parts. |
