Fire Station Alerting System


  • Fire Station Alerting System installed in 35 stations city-wide
  • Integrated to Intergraph CAD System in 2 Communications Centers
  • Leverages Boston’s optical WAN
  • Hardware, Software, and Systems Integration services provided


>> The PURVIS Fire Station Alerting System is used by the Boston Fire Department, having been deployed in June, 2014 in concert with the deployment of their new Intergraph CAD (computer aided dispatch) system.  Deployment of the system is city-wide consisting of all 35 fire stations, a fire training room, the Fire Communications Center, and the Boston Police Department Headquarters. The city can now claim to have a fully automated station alerting practice, based on these completed initiatives.

The FSAS automates the alerting process between the Department’s Dispatch Centers and the fire stations through an interface to the Intergraph CAD system.  It utilizes Boston’s Optical Network (BONET) infrastructure for Internet Protocol (IP) connectivity to all fire department facilities.

The project included the delivery of hardware, software and services.  Hardware provided by PURVIS included a PURVIS FSAS Central Server and Dispatch/Management Consoles in each Dispatch Center, and a PURVIS FSAS Station Control Unit, a UPS and a PURVIS FSAS printer in each fire station.  PURVIS interfaced the FSAS with several of the Department’s existing systems and devices already installed in each fire station, including public address/speaker systems, Federal Alert Receivers and trip lights.

Services provided by PURVIS included project management, system integration, configuration, testing, training, documentation, cutover, and ongoing maintenance/support. Boston has experienced noticeable improvements in dispatch time, including what they call “negative” turn-outs, which is when the first responders are able to deploy for the emergency, with incident information, in parallel with the full dispatch process.

Customization of Automated Notification Systems


  • Phoenix had challenges implementing emergency notifications as part of their UASI (Urban Area Security Initiative) responsibilities
  • PURVIS provided process improvements and integration services around multiple existing notification tools
  • Notification systems and processes were simplified, and self-service features were introduced to ensure up-to-date contact information was available
  • PURVIS arranged for customer training on final, delivered system


>> Phoenix is the 12th largest metro area by population in the United States with about 4.2 million people in 2010 and the capitol of Arizona. It is also a designated Urban Area Security Initiative (UASI) and as such has the responsibility to pull together the public safety resources of a broad area in and around Phoenix.

The Phoenix UASI had been using one of the popular emergency notification systems, but found it difficult to stay current with the myriad contacts and public safety resources that needed to be part of a notification process across multiple municipalities that make up the UASI.  So the systems were in place, but the data management process and database systems needed to be upgraded to make them work and allow resources to be effectively mobilized.

PURVIS developed custom software to enable contact data to be pulled in from multiple external systems, normalized, and then integrated into the centralized notification system.  PURVIS also provided the ability to define response-groups, and created a portal for first responders to update their contact information as needed. When the data management product was complete, PURVIS arranged for delivery of training to the UASI operations team, covering the third-party notification tool and the PURVIS data management module.

Portland, OR
