will show one or more darkened bars from left to right. These bars indicate the relative distance from

the detected activity. The more bars darkened, the closer the activity is to your location. Tornado Alert™

will update the status of conditions once every minute.

Button Functions

Tornado Alert

has two buttons on the front panel. These buttons control the light strobe and audible

alarms of the unit. The buttons have the following actions:

• When no alarms are active, pressing only the left button toggles the light strobe alarm on or off.

Pressing only the right button toggles the audible alarm on or off. After a button is pressed, the

LCD will display the status (on or off) of both alarm types. For example, if you wish to disable the

strobe light, press the left button once. If the display indicates that the strobe is on, press the

button again to turn it off. Pressing and holding both buttons at the same time for 5 seconds will

disable both the strobe light and siren. The disabling of the strobe light and siren only apply to

alarms for SEVERE STORM. TORNADO alarms will always activate both strobe light and siren. To

re-enable the alarms, simply press the left button to re-enable the strobe, press the right button

to re-enable the siren.

• When an alert alarm is active (strobe light is on or siren is on), the user can reset (temporarily

turn off) both alarms by pressing either button. This reset of the alarms is only temporary. New

events will reactivate the alarms as required.

• Button functions are disabled during the “Noise” state.

• Press and hold the button until the desired action occurs. Do not “TAP” the buttons.

Battery

When A/C power is lost, Tornado Alert™ continues operation with the user supplied 9-volt battery.

Using either Industrial Grade or Lithium batteries will provide sufficient power during extended periods

of A/C power loss. Battery life will be reduced by detecting and responding to weather conditions. When

running on battery power, the LCD will display a battery icon on the far left of the bottom row. The size

of the icon will reflect the approximate remaining battery power available. When nearing the end of the

batteries useful life, the unit will sound short beeps of the audible alarm every 5 seconds to notify the

user of a low battery condition.

When operating on battery, ensure that the A/C power has not accidentally become unplugged so that

fresh batteries are not drained unintentionally!

When operating from the battery, Tornado Alert™ will make minimum use of the LCD backlight. When

battery power is critically low, Tornado Alert™ will display the message “Shut Down” on the LCD and

stop monitoring. Once A/C power is restored or the battery is replaced Tornado Alert™ will power back

up and starts the Power up Sequence again.
