When it all goes down, ALERT AM stays up.
Hundreds of communities across America operate ALERT AM Emergency Advisory Radio Stations to tell citizens what to do during incidents that threaten life and property.

No power? No internet? No problem. With the ALERT AM system, listeners receive up-to-the-minute reports and instructions across a 3-5 mile radius (25-75 square-mile area) with a level of detail that makes the broadcasts invaluable.

During non-emergency times, officials use the stations to inform motorists of street repairs, traffic constraints, travel advisories, city history and visitor information.

Information Station Specialists is the sole provider of ALERT AM in the United States and offers 24 / 7 remote technical support for the life of the product. State and local governmental entities may purchase our products without going to bid, if they join the HGACBuy purchasing cooperative as end users. Membership is free. Here's how easy it is to join.

Message Control
The ALERT AM broadcast program can be controlled over a network, USB, landline/cellphone or via a two-way transceiver provided by the operator. Two redundant voice systems, both operable locally or remotely, provide full audio system control which continues to function should telco, network or building access would be lost.*

The ALERT AM system allows the operator to pre-record messages for quick broadcast as anticipated emergency scenarios present themselves.

Broadcasts may also be triggered by ancillary devices, i.e., siren-system closures, switches or other external sources. This allows ALERT AM to quickly switch from broadcasting general information to specific emergency information if disaster strikes. When the National Weather Service issues all-hazard Emergency Alert System alerts for designated counties, they are broadcast automatically, interrupting standard programming. ALERT AM also allows the operator to lock out NOAA alerts if desired. Broadcasting live is easy with the push of a button and can be effected at the radio station itself or remotely from any telephone. An audio processor is onboard to boost ALERT AM’s audio quality and receivable range.

ALERT AM’s digital message players can be stocked with pre-recorded emergency management messages prepared by our professional announcers. to illustrate what’s possible within the system. See free or commissioned recording services.

Antenna Styles
The two most common formats:
  • Yard Style: ALERT AM may be installed at a building with the electronics securely indoors and the antenna pole mounted in the adjacent yard connected by an underground cable. This style is recommended because it is most economical and affords the greatest security for equipment. A 50’ separation from buildings is recommended.
  • Isolated Style: At remote locations where there is no building, a weatherproof cabinet containing the electronics is attached to the antenna support pole. The location must have electrical power and, if equipment is to be remotely controlled, telephone, two-way or network service.
If a yard- or isolated-style installation is not possible, custom installation on a building roof is possible in some instances. Lateral separation of the antenna from large, nearby objects by at least the height of the object is suggested to prevent signal degradation.

We can provide documentation that radio frequency exposure from the ALERT AM antenna does not exceed FCC limits for safe operation.

We will help plan and implement your station, including frequency and site selection, FCC licensing, installation, staff training and the FCC-required field survey and documentation.

Best of all, each system comes with Remote Technical Support and Potential Interference Notification Services (PINS) for the life of the station.
