STRIKE GUARD LIGHTNING WARNING
SYSTEM
This guide is for installation and use of the Strike Guard Lightning Warning System. You are
encouraged to call Wxline, LLC if you have questions concerning the Strike Guard System.
A. ABOUT THE STRIKE GUARD LIGHTNING WARNING
SYSTEM
The Strike Guard Lightning Warning System is comprised of a self-powered Lightning
Sensor, a Lightning Data Receiver (also referred to as “the LDR” or “the Receiver”), and
a fiber-optic communications link. The Sensor must be securely mounted in a well-
exposed place out-of-doors. For the maximum in operator safety and to achieve the
highest reliability of the warning equipment in a lightning environment, the Lightning
Sensor (the “Sensor”) communicates via a non-conducting fiber-optic link with the
Lightning Data that is mounted indoors in an office environment.
The Strike Guard Lightning Sensor:
1. Receives and processes the optical and radio emissions of lightning discharges
within 20 miles of the Sensor.
2. Classifies lightning signals by estimated range to the discharge.
3. Rejects background noise.
4. Transmits serial data messages to the Lightning Data Receiver via a lightning-
proof, fiber-optic link.
5. Performs a periodic self-test of Sensor functions including battery charge level
and transmits confidence messages to the Lightning Data Receiver to ensure that
a healthy Sensor and viable communications link are available.
The Strike Guard Lightning Data Receiver:
1. Receives the serial data transmissions from the Strike Guard Lightning Sensor
and decodes the lightning and status messages.
2. Provides user-set options and thresholds for issuing lightning alarms via front
panel LEDs, audio transducers and contact-closure signaling.
3. Provides the relay contact-closures needed to activate the WAVE Siren System or
to signal other equipment that uses contact-closure signaling.
4. Provides continuous operation with battery backup when commercial power fails.
5. Indicates Sensor status information and Lightning Data Receiver battery level
information.
Unlike a human observer, the Strike Guard Lightning Warning System operates
continuously and automatically. Every effort is made to ensure that the Strike Guard
Lightning Warning System does not malfunction or fail during a local thunderstorm, even
in conditions with very close lightning. The Strike Guard Sensor is self-powered by long-
life lithium batteries that are capable of operating a Sensor in a typical setting for over
