Redundant Trunked Radio Network
The District's Motorola SmartZone 4.1 System—Simulcast Trunked Radio Network—comprises nearly a dozen radio towers all connected by a computerized master controller. This computerized radio controller contains the master radio database and is the primary point for control of audio paths within the network. Though each individual tower site communicates with this master controller, each site can function independently, providing first responders with the solid, redundant communications they need.
This highly specialized system remotely monitors and alerts fire stations. The system also monitors itself by evaluating and reporting the status of the radio towers supporting operational communications. The data control facility of the radio network also performs tasks such as remote intrusion alarm monitoring of tower sites, temperature controls and remote starting/stopping of site backup generators.
