OnAlert Map-based Client for TAR Activation The local operator views a color map of the area included in the Immediate Response Zone (IRZ), wherein he can “zoom in” from the entire area to individual streets. The area is configured according to the customer’s specifications. Configurations can include zone and group subdivisions (e.g., schools, government offices, nursing homes). Additionally, each receiver is individually addressable. The normal background map color is green, but when a zone is selected for notification the color changes to red. |
 |
| Upon receiving word of an emergency, the operator selects the recipients
for the warning message.
To select the entire coverage area involves clicking a single
button on the screen - "Select All Zones." |
 |
|
| If only certain zones need to be activated, the operator clicks
the identifying numbers of the affected zones in a scroll bar on
the right side of the screen. These numbered zones can be tailored
to group identifiers (e.g., utilities, schools, hospitals, nursing
homes, southeast, north). |
 |
|
| Next, the operator clicks to select the pre-recorded audio message that needs to be sent (e.g., evacuation, all clear, weather alert). |  |
|
| Finally, the operator clicks the “Send Message” button. To prevent accidental activation, a dialog box requests verification that the operator indeed wants to send the message as prepared - displaying both the selected zones/groups and the selected message. |  |
|
| The WSI rack-mountable controller encodes the message for the specified receivers and ties push-to-talk and audio lines to the broadcast transmitter. |  |
|
| The message is transmitted to the designated receivers. |  |
|
| When a valid command is transmitted, the warning receivers emit a loud alerting tone in homes, businesses, schools, hospitals, factories, and other locations. This is followed by the pre-recorded or live verbal message. |  |
|
| Non-audible alerting instruments, such as strobe lights and vibrating devices, can be easily connected to the ONALERT receivers to notify hearing- and sight-impaired individuals of impending danger. |  |
|
| From the time the operator receives word to send a warning, until the warning is actually sent, takes less than fifteen (15) seconds. |  |
