NOTE
To prevent damage from local electrical disturbances typically
associated with a thunderstorm, bond the WAVE Transmitter,
QPS Transmitter, or other connected equipment to the LDR. A
bond wire should connect the LDR’s chassis with the metal
chassis (or ground) of the connected equipment. This bond wire
should be short and straight.
H. SOME NOTES ON OPERATION
A Sensor Battery Low message will cause the Sensor Battery Low LED to turn on. It will
also cause the Sensor Self-Test Fail LED to turn on because the Sensor Battery Low
condition inhibits the Sensor self-test and hence is a Self-Test Failure.
A Sensor Self-Test Fail message will cause only the Sensor Self-Test Fail LED to turn
on. Selection of Fail for the AUX RELAY means that No Communication, Battery Low or
Self Test Fail conditions will cause relay actuation until all failure conditions are cleared.
These features allow enhanced failure indication by the AUX RELAY.
For example, if No Communication is the only failure condition, the AUX RELAY will be
actuated by the occurrence of the No Communication condition and will be cleared by
the first valid message from the Sensor provided it is neither a Self-Test Fail nor a
Sensor Battery Low message.
I. CHANGING BATTERIES
The LDR provides long-term, primary battery back-up capability to ensure continuity of
operation during thunderstorms when commercial AC power reliability is often
compromised. For longest battery life and ease of use, the LDR uses common alkaline
C-cell batteries just like those used in consumer products like flashlights and portable
radios. Alkaline C-cells are available at most drug, grocery and hardware stores.
Batteries should be changed soon after the LDR shows the Battery Low condition on the
front panel or every 2 years whichever comes first. Do not confuse the Sensor Battery
Low indication with the Receiver Battery Low indication. For longest battery life and best
performance, always buy and use new, fresh alkaline C-cells from the same package.
Do not mix old cells with fresh cells. Never touch the contacts of batteries that are being
installed. Properly recycle old batteries. Use only standard (non-rechargeable) low-cost
alkaline C-cell batteries available at any drug or hardware store.
NOTE
Do not use Lithium C-cells. Do not use Nickel-Cadmium (NiCad)
C-cells. Rechargeable alkaline C-cells are acceptable for use but
may offer less Amp-hour capacity, i.e. less back-up time than
alkaline primary cells.
All relay actuation is prevented after the Battery Low condition is
detected and indicated. The LDR will continue to give normal
audible and visual indications after Battery Low is indicated but
all contact closure signaling will cease – thus WAVE Siren
functions will not occur.
For proper safe operation of the Strike Guard Lightning Warning
System it is essential to have a functioning battery back-up
system available. The LDR relays cannot be controlled reliably in
thunderstorm conditions without good batteries.
Failure to change the LDR batteries every 2 – 3 years increases
the chances of battery leakage, which can severely damage the
