IRiS electronics

AEL/SEL Category 04AP-09-ALRT

Highly Compact with the Exclusive Optional Capability for Cell Modem Control
Built for speed and portability, IRiS electronics are housed in high-impact, weather-resistant cases. The quick-erect antenna system folds up, allowing the entire station to be set up in 10 minutes by one person.

IRiS is FCC-licensed* to an operating territory such as a county or state. The signal is typically announced to the public by portable signs, positioned at the periphery of the coverage area. Motorists receive broadcasts on standard vehicle radios, over 25-75 square miles.

The stations are priced affordably so multiple units can be deployed simultaneously at different locations during an emergency as required.

IRiS Carry Cases
"Deployment went quickly and was completed in about 20 minutes.
The coverage was phenomenal and absolutely unbelievable that a
10-watt station could be heard nearly 6 miles away in an urban
environment with many tall buildings. Overall, the system was an
excellent investment."

John Black
Wireless Communications Manager City of Long Beach, CA
Portability becomes an instant asset during emergencies, allowing re-establishment of the signal from a new location quickly.

Portability also makes IRis especially useful at large public gatherings for broadcasting key information, i.e., schedules, traffic, parking, safety and critical instructions for patrons approaching or exiting.

Programming may be controlled using flash drives through a USB port or uploaded via a network connection or the optional cell modem.  
Key Advantages  
  1. Third-party companies are not needed for continuing service, carrier or activation fees, and, therefore, do not need to be relied upon during emergencies.
  2. When the AC grid goes down, IRiS still works if operated on a generator or battery pack; and receivers are in vehicles. AM radio methodology has been active for 80 years and is not likely to be supplanted anytime soon.
  3. Citizens do not need to purchase special devices to receive Iris broadcast messages.
  4. IRiS stations allow public officials to speak directly to drivers without distracting text messages on portable devices.
  1. Radio messages vastly supersede text services in the sheer amount of information and level of detail that may be delivered efficiently.
  2. This aural medium also allows officials to speak to the public in a natural, person-to- person way that might be calming during an emergency.
  3. IRiS comes in an easy-to-go format but may be used in a fixed location when not needed on the road. Parts are available to make the antenna location permanent if needed.
  4. IRiS’ Transmitter features full-fidelity 5000 Hz audio; Digital Voice Player never loses messages due to indelible memory. Messages are non-proprietary in format (mp3- based) for easy sharing, transfer and storage.
IRiS operators who are members of AAIRO - the American Association of Information Radio Operators - can obtain no-charge recording of general broadcast messages by professional announcers. AAIRO is a free service. Join at
Who Uses Portable Information Radio Stations

County Public Health:
Los Angeles County has a station, deployable anywhere within its populous area on a moment’s notice for motorists queuing at vaccine distribution points. Bucks County PA, Williamson County TX and Worcester County MA have multiple units. Allen County IN emergency director Brad Witte explains, “We will use it to provide citizens instructions to field clinics, how to proceed thru the clinics and what to expect after they get there ….”

Emergency Medical Services: Hospitals such as Porter Health in Indiana and various Texas regional advisory councils.

Emergency Management: Counties in several states have units to set up in emergencies, and a number of them have several. Sweetwater County WY with an 11,000-square-mile district uses 3 units to reach motorists who might otherwise be missed. Says coordinator Judy Valentine, “We will provide updated information; … in addition, will deploy them when we activate our mobile command post or CERT animal rescue, shelter or other volunteer teams. We also plan to use them for civic and public health events, disaster exercises and a multitude of other

State Agencies: ND Emergency Management owns 3 units that can be deployed anywhere in the State at a moment’s notice. In other states, county-owned units are licensed with statewide operating territories so counties can share the resource.

Communities: Many operate these stations from fixed locations with the expectation of deployment when needed.

Fire Districts: Yosemite National Park and the USDA use IRiS for wildfires.
