Only ALERT AM provides high quality message recording (16-bit sampling rate), 80 minutes of recording time, 1,000 broadcast messages, automatic station identification with 5500-Hz dynamic range. Fifty message playlists may contain hundreds of broadcast messages, up to three live sources (each with independent timing control), commands for up to four external relays, other (nested) playlists and differing output levels for each audio output. Playlists may be appended after they are created. Voicemail-style natural voice operation with 800-word/phrase capability. Three audio inputs for separate and independent live program feeds, each with independent audio level controls. One- to nine-digit security access code, defeat-able phone prompting, programmable locally or remotely. User-settable number of retries and timeout period for maximum security. Five-second and full-message survey monitoring of all stored messages and playlists. Eight prioritized control closures to trigger message sequences remotely. Control closure prioritization allows automatic interrupts for emergency messages and automatic National Weather Service all-hazards radio notifications (weather and EAS). Prerecorded messages by professional announcer for advisory radio application, ready for broadcast immediately. Rack-mountable, slim design, 1 RU in height. See the NX8R Digital Message Player webpage.

Only ALERT AM features a NOAA All-Hazards receiver that is field programmable and upgradeable to remain current with changes in NOAA EAS/weather hazards. Only ALERT AM captures the most recent warning activation for replay by system operators. Only ALERT AM can change to new message patterns, when the National Oceanic and Atmospheric Association (NOAA) sends All-Hazards (weather and Emergency Alert System) warnings.

Only ALERT AM allows special broadcast messages to be aired automatically in conjunction with NOAA All-Hazards Specific-Area Message Encoding notifications, outdoor warning system activations or Emergency Operations Center control panel switches.

Only ALERT AM allows full control of the digital message player via push-to-talk style transceivers (not included) parallel to and with priority over telephone control, using the same commands, protocols and voice prompts.

Only ALERT AM allows an operator to run the station by computer (Workstation Audio Control or SignalcastIP) while also retaining the ability to record messages and control station operations via telephone if AC power goes out.

Only the ALERT AM system synchronizes “repeater” stations (to create larger coverage areas) without relying on vulnerable dialed-up telephone links to distribute audio in times of emergency. See the "ALERT AM RealTIME Transmitter Synchronization" webpage. Optional ALERT AM wireless audio links make synchronized audio connections for high reliability with no monthly operating charges; i.e., do not rely on tele/cell phone lines during emergencies, preventing synchronized AM stations from becoming disconnected, broadcasting the wrong messages. Additionally, Wireless Audio Links operate on the same battery backup system as ALERT AM, so when power goes down, they stay up. See the "Wireless Audio Links" webpage.

Only the ALERT AM's antenna is black in color to discourage ice build-up and is finished with a special UV-resistant architectural-anodization process to prevent color fading. If installed in adjacent building yards, ALERT AM requires only that a support pole be set. Not required are large, buried, copper-wire groundplane installation or chemical-emitting ground-pipe (hollow rods) burial. Only the ALERT AM Emergency Advisory Radio System can include a Vertical Profile Antenna System that does not require a groundplane. Major site disturbances such as surface trenching or drilling for the installation of deep ground rods is not required. The Vertical Profile Antenna System also means: 1) the antenna's cables and arrestors are inside the pole for safety and security; 2) theft of copper ground wire is impossible; 3) it is possible to move the system if required; and 4) the aluminum pole is attractive in conjunction with public buildings and may be painted as needed.

Only ALERT AM works in conjunction with solar-powered flashing advisory signs via communities’ UHF/VHF Radio Systems to turn on/off beacons remotely. These signs are the key to notification of the community that an emergency message is being broadcast. See the "Flashing ALERT Signs" webpage.

Only ALERT AM offers a battery backup system capable of keeping the station on the air for a full 4 days. The pack fully recharges in just 7 hours.

Only ISS systems employ nonproprietary designs. This means that, in the future, you may change components as needed without the requirement to return to ISS; i.e., simple wiring diagrams are provided, so you can service equipment yourself, if you choose, or have a third party assist – all with full ISS support.

Only ISS transmitter frequencies are synthesized, not crystal controlled, allowing simple frequency changes in the future, if necessary.

Additionally, only Information Station Specialists offers technical assistance for the life of the (ALERT AM) product. ISS supports today radio stations that first went on the air in the 1980s. ISS’ staff of engineers has more than 60 years of combined experience specifically in the kind of radio technology under which ALERT AM operates (FCC Rules, Part 90.242).
