The UL-864 Listed GS3055-ICF by Concord, Ontario, Canada-based DSC, part of Tyco Security Products, is a universal cellular fire alarm communicator.
When used as the sole communication device, the product will replace the phone line connections on the fire alarm control panel and will send all events across the GPRS cellular network to the monitoring station. In backup mode (dual communication technology), the communicator assesses the phone line connection status and sends all events across the cellular network only in the event of phone line failure.
