  • Built-in decoder tool on the display allows you to convert any P,N,C, or A message into its decoded components.
  • Free software updates for one year included with your purchase of Contrail Field Decoder software.
  • Coming soon! Message creation and transmission for two-way testing of ALERT and ALERT2 field components.

StormLink™ IQ Receiver

When the software is used with the StormLink IQ Receiver (shown above), you have a simple low cost mobile solution for receiving and decoding your field sites. Through the web browser interface, easily change between frequencies, decode ALERT2.

The ability to switch between ALERT or ALERT2 decoding; simultaneous decoding of multiple frequencies using either ALERT or ALERT2. You will be able to see a message as it goes completely through your network—as it is sent from a transmitted site in one protocol, and then repeated through a repeater in the same or another protocol.

StormLink RF ReceiverStormLink™ RF Receiver

When the software is used with the StormLink RF Receiver (shown right), you have a radio-based ALERT2 receiver with controls that allow you to switch frequencies and receive/decode either ALERT or ALERT2 messages.

Future upgrade path: The StormLink RF Receiver will be upgradable to a 2-way transceiver which will allow it to transmit and receive ALERT or ALERT2 for testing repeaters and two-way sites such as those used by flasher or siren systems.
