StrikeAlertStrikeAlert is a small and affordable personal lightning detector, that can provide an early warning of approaching lightning strikes from as far away as 40 miles, and lets you know if the storm is coming your way
An audible alarm sounds when there's a detected strike, whilst a corresponding LED light illuminates accordingly at lightning distances of 20-40 miles, 12-24 miles, 6-12 miles, and within 6 miles
The detector is housed in a small pager-like casing that can be conveniently clipped on a belt loop, and runs on a two AAA batteries. It's is perfect for those who administer outdoor sporting events and outdoor recreational activities
Convenient Size & Weight
Small and impact-resistant, StrikeAlert clips to your belt, golf bag or backpack. Take it wherever you go!
Audible Warning
An audible warning sounds when lightning is detected within the local vicinity
Low Power Consumption
Up to 100 hours of operation from two AAA batteries
Easy to Use
With the flip of a switch, you can see the lightning strike distance, track the storm direction and view battery life.
FEATURES:
Power Switch
The power switch has three positions: On, Off and On with tone. The switch may also be depressed to indicate the direction of storm movement
Battery Check
When first turned on, StrikeAlert performs a battery test. The LEDs will indicate the status of the battery, with each LED indicating approx 20 hours of operation. The LEDs will light up, beginning with the red LED and leading up to the current battery level. The current battery level will be the final LED to light and will remain lit for two seconds. StrikeAlert will then begin its normal operation.
Normal Operation
During normal operation, the green LED will be on continuously to indicate StrikeAlert is monitoring for lightning strikes. If the green LED is blinking, StrikeAlert is detecting a source of interference.
Detecting Lightning Strikes
When a lightning strike is detected, StrikeAlert will light the appropriate LED indicating the distance of the strike. This LED will remain lit for two minutes- unless another strike occurs during that time.
If a more recent strike is further away, the LED indicating this distance will light for two seconds, and then return to complete the two minutes from the nearest strike. If a more recent strike is nearer, it will replace the previous LED reading. This LED indicator will be held for two minutes. This allows the user to see all the lightning activity within a 40 mile range, giving clearer visibility to the nearest strike in the last two minutes.
If the power switch is in the "On with Tone" position, StrikeAlert will also generate tone(s) indicating the distance of the strike along with lighting the appropriate LED. This allows you to determine the storm's activity without having to monitor the LEDs.
Storm Direction
Strike Alert trends the detected strike distances over the last five minutes to help determine if a storm may be approaching or departing.
Back To Top By depressing the power switch, the LED will change to one of three patterns:
If the LED cycles from green to red, the storm is approaching.
If the LED cycles from red to green, the storm is departing.
If the LED cycles from the center LED to the outside LEDs, the storm is stationary or there's not enough data to determine the direction of the storm.
Direction cannot be determined if there has not been enough strikes to identify a trend, or StrikeAlert has not been running long enough. Approximately five minutes is needed in the presence of regular lightning strikes, to assist in the determination of direction.
Interference
StrikeAlert is designed to be used outdoors.
While StrikeAlert will work indoors, its ability to detect lightning strikes can be adversely affected by common sources of electromagnetic emissions, such as:
• CRTs - (televisions or computer monitors)
• Motors and engines
• High-powered electronics equipment
Moving the StrikeAlert away from these devices (usually a few feet) should allow the detector to return to normal operation.
If StrikeAlert is receiving interference due to such electromagnetic emissions, the green LED will blink or may give a false lightning indication.
The static generated by some garments may also produce a false indication. Again, moving the detector just a few feet away from the source of the interference should allow StrikeAlert to resume normal operations. This will be indicated by the green LED remaining constantly lit.
IMPORTANT
Hand held detectors such as the Strike Alert detect the unique radio frequency signatures associated with already active lightning.
Such devices CANNOT predict a first strike, or monitor any of the measurable conditions leading up to a first strike.
Those who may look to use the benefits of hand held detection technology, must do so knowing that the devices have these limitations, and in every instance when the detector alerts, that certain safety procedures must be immediately enacted, such as communicating the lightning warning to those who may be at risk, and direct those at risk immediately find a safe area, until such time as threat has seen to have passed.
The use of Lightning detection equipment should be used in conjunction with the 30 /30 rule ( refer The 30/30 Rule )
It is recommended that the use of any Lightning Warning or detection systems be used strictly under a Lightning safety policy which describes the known safe locations where persons should wait out the threat, and highlights those unsafe locations where persons should seek to avoid.
Further safety procedures can be found at safety procedures.
