NASA-Proven Technology Based on 40 Years of Research                                                                                        By tornadoAlert ®
Increase your time to get to safety with the Direct Storm Sensor DSS.20, which directly scans for atmospheric signatures associated with severe storms and alarms you immediately.

DSS.20's patented technology is not dependent on NOAA Weather Radio reception, weather apps, wireless internet or any special services.

It monitors weather threats, as a thermometer directly monitors temperature. There are no ongoing costs and there is no service to be interrupted.
Direct Storm Sensor  DSS.20

This revolutionary device incorporates NASA-proven technology to alert you when damaging storms or tornados approach your location. Severe weather can develop so suddenly that statistically, the National Weather Service and internet-based services are only able to issue advance warnings 60% of the time.*  But the Direct Storm Sensor (DSS.20) continually monitors atmospheric conditions directly and notifies you with both visual and aural alarms when violent storms are close by, providing you valuable time to seek safety. It includes a proximity read-out, so you can determine how close a severe storm is to your location in real time. Indications include tornadic activity, the presence of severe storms and lightning. Field testing demonstrates a 95% accuracy rate, making a Direct Storm Sensor a natural adjunct to conventional weather warning systems.

   On-screen hazard indications:
  4. Storm (not Severe)
  6. NO Threat

   Onboard battery backup to provides up to 24 hours of protection during AC power loss.

   Strobe and 90 dB siren – can be defeated for lower level events.

   LCD screen with backlight for low-light operation.

   Ideal for sight- or hearing-impaired individuals.

   External port to activate ancillary / secondary warning devices.

   AC / DC power.

   Easily portable. Optional vehicle power adapter.

(*) NOAA / NWS and internet-based services can only provide warnings to you, if you are within range of their services and your reception device has power at the time that the warning notification is issued. You must also be in a location where it is anticipated that severe weather is likely to occur. Warning delays are inherent because of the time required to make a determination of storm severity and then issue the warning notification, both of which require human input.

(**) Free shipping within the contiguous United States. Fast freight or shipping to Alaska, Hawaii or outside the United States is extra and can involve a third-party agent.

Information Radio Stations is a generic term synonymous with Travelers Information Stations (TIS), Highway Advisory Radio Stations (HAR) / Highway Information Systems & Low Power Radio Stations (LPR). Operation of the stations is governed by FCC Part 90.242 Rules. A FCC license is required. Information Radio Stations may be fixed or portable. Subcomponents may include transmitter, antenna and ground system, digital voice player, wateter, cabinet with conventional or Corbin locks, lightning arrestors for RF, power and telephone lines, coaxial cable. Most stations employ black maximized antennas to discourage ice accumulation and security measures to prevent unauthorized program access. Options include synchronization, battery backup, solar power, remote programming by local, network or telco, multi-station audio distribution via RF or LAN / WAN or wireless network.
