Automated Dispatch Overview

The PURVIS FSAS integrates seamlessly with a community’s computer-aided dispatch system (CAD) to automatically and nearly instantaneously deliver key incident details to necessary Fire and Rescue personnel. The PURVIS FSAS uses proven technology to convert dispatch data to natural sounding speech that is clear and easily understood. Automated announcements can be automatically broadcast over an existing radio network and simultaneously delivered to specific fire stations needed for a call. Key features include:

  • Instantaneous delivery of incident notifications
  • Automated Text-to-Speech technology that allows system administrators to quickly and easily modify pronunciations
  • Integration with VHF, UHF, 700MHz, 800MHz, and P25 radio systems to provide automated voice, analog tones, digital tones and data transmission via radio
  • Messaging and manual back-up alerting capabilities
  • Built-in system management and monitoring
  • High-availability design and implementation

Automated Dispatch (Servers)

The “brains” of the PURVIS FSAS, the Central Server maintains connectivity and configuration information, processes CAD data to provide automated dispatch over radio and to the fire stations, and self-monitors for system health and status. While it is possible to install the FSAS with a single server, the addition of a second server provides a superior level of redundancy. With two servers deployed, both operate simultaneously in “active-active” mode. In the event of planned or unplanned downtime of one, the system automatically notifies support personnel while seamlessly continuing all operations from the second server.

Central Servers can be physical servers, virtual servers, or a hybrid combination using one of each.

Physical Servers
  • Capable of supporting 100+ of stations
  • Can be installed on your site in location(s) of your choice
  • Easily expand to support a virtually unlimited number of stations
  • Can be physically separated for geographic redundancy
Virtual Servers
  • Capable of supporting 100+ stations
  • Expand to support a virtually unlimited number of stations
  • Host virtually with no need to buy, install and maintain separate hardware
Hybrid (Physical & Virtual Servers)
  • Leverage existing resources to run PURVIS FSAS software
  • Provide the same active/active level of redundancy as two physical servers or two virtual servers
  • Capable of supporting 100+ stations
  • Expand to support a virtually unlimited number of stations

CAD Interface

For a fully automated alerting process, the PURVIS FSAS communicates with your CAD system. The CAD interface is what makes that communication possible. PURVIS engineers have deep experience interfacing the PURVIS FSAS with a variety of CAD Systems, including but not limited to: NexGen, Hexagon/Intergraph, Motorola (Edge/Spillman, PremierOne, Premier), Central Square (Inform, Superion ONESolution, CommandCAD, IMC), Tyler Technologies/New World, EnRoute, Southern Software, ProPhoenix, and Alpine Software/RedAlert.

PURVIS currently offers three ways to interface the PURVIS FSAS with a CAD system:

Application Programming Interface (API)
  • Enable seamless communication between any CAD system, the servers, and the stations
  • Interface with numerous CAD providers, including Motorola, Hexagon, Central Square and many more
  • Allow for full-station automation functionality, including relays (turning devices on and off) and zoning
  • Support bi-directional communication between the PURVIS FSAS and the CAD system
File Directory
For agencies that don’t need/require a full API, the File Directory Interface provides a cost-effective solution.
  • The file directory interface makes use of a shared file folder
  • When a dispatch occurs, store files in the shared file folder, constantly monitored by the PURVIS FSAS
  • Upon receipt of a new dispatch file, the system will automatically receive and automate an alert accordingly
SMTP (Email) Interface
For agencies that don’t need/require a full API or are not allowed to integrate due to resource sharing, the Email Interface provides a cost-effective solution.
  • Push an email with CAD information to the central server following a dispatch
  • Allow for server to review the data within the email and automate the alert accordingly
  • Requires less resources to deploy quickly and efficiently

System Management

There are two ways authorized users can manage the PURVIS FSAS system:

FSAS Portal
  • Allow authorized users to access the PURVIS FSAS system from ANY computer using an internet browser and network connectivity to the Central Servers on the network
  • Allow for system administration or manual alerting
  • Configure automated voice pronunciations
  • Utilize existing computers and monitors; no need to purchase additional displays
Dispatch Management (DM) Console
  • Provide at-a-glance information about the PURVIS FSAS system and connected components like faults or active incidents, from a single touch screen screen
  • Allow access to system administration and manual alerting
  • Provide audible and visual alerts to notify of any network or system faults or failures
  • Install with existing hardware for cost savings

Station Alerting Overview

Within the fire stations, the PURVIS FSAS automates and streamlines station operations. All stations required for a specific event are alerted simultaneously via your existing network. Redundant alerting over radio, or a secondary data connection, ensures no loss of station alerting in the event of a network failure.

Key features include:

  • Supports integration with legacy station equipment
  • Clear Text-to-Speech technology
  • Configurable for day/night alert settings
  • Configurable alert tones
  • Zoning capabilities and ramped audio technology reduce stress on first responders
  • Incident data can be delivered to a variety of station devices, including printers, lights, and message boards
  • Microphone functionality to support in-station paging operations
  • Ability for station to acknowledge alert back to dispatch

How do you want alerts delivered to the stations? The PURVIS FSAS offers options for both radio connectivity and IP connectivity. When multiple paths for connectivity are deployed, the PURVIS FSAS does not require a “primary” and “secondary” alerting path. Instead, the system can send alerts over all available connections simultaneously.

The PURVIS FSAS maintains active IP connectivity to all Central Servers, Radio Interfaces, Station Control Units, and other connected station components and devices. The status of each connection is monitored in real-time using “heartbeats.” This back-and-forth communication allows the FSAS to verify connectivity.

If the PURVIS FSAS detectes a down connection, an automatic notification is immediately sent to dispatch, station, and support personnel.

IP Connection
  • Connect directly with an existing IP connection (can support 2 IP connections to each station) in the fire station for IP communications with dispatch
  • Opt to utilize IP data over WAN, fiber, radio, cellular, or other connection types as a secondary IP alerting path
  • Utilize a secondary IP path, to send dispatch alerts via data over both IP paths allowing the system to immediately activate when the first alert reaches the station
Radio - Audio Only
  • Seamlessly connect the station radio to the PURVIS FSAS Station Control Unit to deploy radio audio over station speakers at any time
  • Utilize radio as an automated form of backup alerting, in the event of an IP network failure
  • Turn on-off as needed, by station zone, using the PURVIS FSAS Touch Screen

Audio Alerting

A key benefit to the PURVIS FSAS is its ability to integrate with a variety of commercially available, off-the-shelf (COTS) equipment and devices. In many cases, it is possible for a new FSAS to connect seamlessly to existing speakers and other audio devices, adding a cost-saving benefit to our clients.

Indoor Speakers
