See below for more specifics on some of the system components and device options

Central Server

The Central Server maintains a central repository of all configuration and connection information and is responsible for maintaining connectivity to fire stations, the CAD interface and the Dispatch/Management Console. During operation, the PURVIS FSAS Central Server processes CAD data transmitted by the CAD interface and provides dispatch data to the fire stations and remote personnel involved in the incident.

Dispatch Management Console

The PURVIS FSAS management console is a touch screen computer providing a simple, user friendly, graphical interface designed to allow for efficient public safety communications. It provides an interface for system monitoring, configuration and reporting.  Additionally, manual alerts and general announcement messages can be sent to station and remote personnel via the DM console.

Radio Interface Unit

The PURVIS Radio Interface unit is a rack-mountable device that connects the PURVIS FSAS Central Server into your existing radio broadcast system, so incident notices, converted to audio via our text-to-speech technology, are automatically delivered over existing radio channels.

Station Control Unit

The FSAS Station Control Unit (SCU) is installed in each fire station and any other location which might require alerting. It is connected to the Central Server and operates all of the communications devices and appliances, including speakers, lights, cameras, zone controls, and more. It can be installed as a “black box” or with an integrated display.

SCU Touch Screen

Customers have the option of implementing the PURVIS Station Control Unit (SCU) Touch Screen display as a remote access/control device or as a display panel that is physically integrated with the SCU.  It can provide a read-out of the incident report, a map of the incident location, consolidated incident reports, color-coded alerts, and an interface for zoning control and acknowledging alerts back to dispatch.

Digital Light Bars

The Digital Light Bar is a multi-colored light tower with up to five (5) individual color segments.  Available colors are white, blue, green, amber, and red.  Colors can be used to indicate responding units.


The Red Night Vision Light is a low intensity LED light that illuminates pathways, doors, and stairs to provide safe egress at night. These lights reduce the startling effect of night time alerts and don’t have a negative impact on the night vision of station personnel.

Single Color Trip Lights

The Single Color Trip Lights allow the station staff to easily see when an alert is received. These lights are available in stationary, rotating or flashing form factors.


The PURVIS FSAS is able to interface with many existing sound, intercom, and public announcement (paging) systems. If new speakers are installed, PURVIS recommends self-amplified speakers in each audio zone, which provide a more redundant and highly available solution. PURVIS can supply various self-amplified speaker types to meet the installation requirements. Speaker types include: outdoor/high noise (drive bay); wall/ceiling. Speakers can also be installed with integrated unit lighting.

Ambient Noise Sensor

Ambient Noise Level Sensors detect the ambient background noise and amplify the audio being played to the associated speakers. In areas of the fire station where noise levels can be high, such as the drive bays, the PURVIS FSAS uses these sensors to ensure that critical audio alerts are audible over the background noise.

Zoning Remote

 The PURVIS FSAS offers a Zoning Remote for fire stations that share a common dorm or bunk area with multiple apparatus units, officers, chiefs, or other general offices.  The Zoning Remote is a wall mountable device that allows the user to select the alerting preference.  The alerting preference is based on the specific apparatus being dispatched – or the user may select all apparatus.


The PURVIS FSAS Rip and Run printer is a thermal style printer. This printer type decreases the likelihood of failures associated with ribbons, toner, ink cartridges, and paper. Incidents received at the fire station are printed immediately to the printer. The information printed typically includes the incident type, the address, the apparatus dispatched, and other comments that can be configured to your specific needs.

Flat Panel Display

The PURVIS FSAS Flat Panel Display is available in various sizes from 13 inches to more than 46 inches and can be placed on walls throughout the fire station. These can show the fire station staff the incident address, cross street, responding units, incident type and turn-out time.


LED Reader Board Display

The PURVIS FSAS Reader Board Display provides incident information on high contrast and bright LED devices. The LED displays are easily readable at great distances making them ideally suited for installation in drive bays or other large spaces where high visibility is required. These displays will typically show the fire station staff the incident address, cross street, common name, responding units, incident type and turn-out time.

Turn-out Timers

The PURVIS FSAS provides a highly visible wall mounted Turn-Out Timer to track response times. The Turn-Out Timer begins counting upward in one second increments when the incident is received at the fire station. The timer continues to count upward each second until the responding apparatus have acknowledged the incident. The system can also be customized so that the timer will stop when user-defined criteria has been met. Timer data is logged in the database, and can be accessed to perform Turn-Out Time data analysis.

Apparatus Presence Detector

The Apparatus Presence Detector provides detection of apparatus in drive bay locations. This information is used to record turn-out time on a unit by unit basis.

Front Door Camera/Doorbell

PURVIS can install a camera at the front-door of the fire station, along with 2-way audio communications.  This provides a video feed into the station and also back to the communications center (CAD).  Any visitor to the fire station, can get immediate assistance, either from station personnel who can get a “visual” on the visitor, or from the communications center if station personnel may be away or unavailable.

Manual Activation Button

The Manual Control Button can be configured for a variety of operations, including manually activating the system if connectivity with dispatch is lost or if an incident occurs at the fire station requiring immediate response, incident acknowledgements, system tests, and more.
