Product Frequently Asked Questions
2.1 Batteries and Photo-voltaic Solar Panels
Question: How long does the battery last?
Answer: Conservatively, 3 years. In
general, 5 years or more.
Question: How much do the batteries cost?
Answer: Approximately $30 each. 1 battery is required per head.
Typically, a beacon would be composed of 2 opposing heads.
Question: Where can replacement batteries be purchased?
Answer: Hawker Energy Product Distributors www.enersysreservepower.com
or JSF Technologies
Question: What is the power output of an Active Beacon solar panel?
Answer: Each solar panel in an Active Beacon is rated at 4 watts and
charges a single 2V 25 Ah battery cell.
Question: How long can an Active Beacon run for without solar recharging?
- Answer: Without any additional solar recharging, a fully charged unit
will continue to run for almost one year, provided the light head(s) are not
activated. The Active Beacon has been verified through field tests to provide
300 20-second LED flash cycles per day for one month of continuous operation
without any solar recharging.
Question: Is the angle orientation of the Active Beacon solar panels an
important consideration during winter months?
Answer: No. Even with the angle of incidence of the solar energy in
the northern region of Canada, the Active Beacon solar panel efficiency is
better than 90% when compared with an angled tracking solar panel.
2.2 Installer Configuration
Question: Can the flash duration be adjusted?
Answer: Certainly. The adjustment knob is located on the back of the
LED module. Duration settings are 15, 20, 25, 30, 45, and 60 seconds.
Question: Can the flash pattern be adjusted?
- Answer: Yes. There are two flash patterns:
- a. High intensity; Four 125 ms pulses with 50% duty-cycle followed by ½
second off
- b. Standard MUTCD ½ second on, ½ second off
2.3 Wireless Considerations
Question: What does the wireless technology do?
Answer: Wireless RF signaling is used to send activation signals to
all beacons in the vicinity of a crosswalk. Each JSF Technologies Active
Beacon assembly has the capability to receive activation signals. Beacon
assemblies that have push-button connected will be able to send activation
signals.
Question: What is the wireless range?
- Answer: The range is conservatively specified at 100m (328ft). This
allows JSF Technologies Active Beacon to be installed in advance of the
crosswalk.
Question: Is it possible to support multiple crosswalks in close proximity?
Answer: Yes. Because the JSF Technologies Active Beacon system has a
configurable address switch, conflict-free operation is operation is achieved,
even when up to 15 Active Beacon systems are installed within close proximity.
Question: How many Active Beacon systems can be installed at crosswalks in
close-proximity" to one another?
Answer: The original Active Beacon system close-proximity limit was 8.
This has since been upgraded to 15 in the latest version of the product.
Please check your installation guide (Product Manual) or contact JSF
Technologies directly for the maximum limit supported by your Active Beacon
unit(s).
Question: What is the JSF Technologies CWSD remote transmitter for?
Answer: The remote transmitter is used in any situations where the
push button needs to be independent of a beacon assembly (e.g. a fire-hall
with a warning device in the street adjacent the main building). The remote
transmitter is not required for most typical installations.
2.4 Miscellaneous
Question: Can I use LED lense panels manufactured by companies such as
GENELEC with my Active Beacon system?
Answer: No. The light JSF Technologies Active Beacon has been
carefully engineered to provide the most power-efficient LED solution
available through any manufacturer (measured up to 4 or more times as
efficient as competitor’s products). This efficiency allows the JSF
Technologies Active Beacon to remain small, light and esthetically attractive
because large numbers of batteries and solar panels are not required to
sustain its operation over long periods. Of course, this also makes the Active
Beacon more cost-effective for the customer as well.
Question: Are there any other advantages to using the JSF Technologies Active
Beacon System?
Answer: Yes. One not-so-obvious feature of the JSF Technologies Active
Beacon is that it is less likely to attract the attention of vandals as
compared to similar solar powered systems. Because the solar panels are small
and oriented horizontal to the ground-plane, they are less conspicuous.
Question: What sort of warranty is applied to the JSF Technologies CWSD
system?
Answer: The system has a one-year warranty, excluding batteries and
damage caused through vandalism.
