APX Personnel Accountability Application (APAA)

APAA modernizes fireground personnel accountability activities

APAA modernizes fireground personnel accountability activities

A personnel accountability solution that meets the demands of modern firefighting through an easy-to-use system. The immediate benefit to fire departments is improved emergency alert handling, faster roll calls or personnel checks, and reduced fireground confusion.

Learn More

APAA works within the ASTRO 25 trunked radio systems to leverage capabiltiies provided by trunked radio networks.  APAA also works in conventional, or talkaround mode.  Standard functionalities for both trunking and conventional include accountability registration, PTT ID display, customizable tactical alert messages (e.g., evacuation, rollcall/PAR), automatic tactical alert acknowledgements, clock/timer utilities, unit assignment, radio polling, radio power down indicator, channel-change indicator, and battery level indicator. For trunked environments only, features also include cohabitation of APAA and dispatch consoles and dynamic regrouping of responder radios.

Radio Hardware
APAA use on trunked radio systems requires the ASTRO 25 7.17 System Release or later.  RF Site equipment must all be G-Series hardware.  Responder radios must be APX™ 4000, 6000, 7000 or 8000 portables.  Incident commander laptops or tablets must have a dedicated APX radio connected to it to monitor the trunking system or conventional channel used for incident scene communications.  When used in trunked radio systems, the incident commander laptop or tablet requires a data connection to the Accountability Server that resides in the CEN of the trunked radio system.  This data connection can be a broadband connection or can use the Integrated Voice and Data (IV&D) capability of the ASTRO 25 system.  This data connection is in addition to the dedicated APX radio connected to the laptop or tablet.

Computer Hardware

APAA client software used on the incident commander laptop or tablet operates on Windows XP, Windows 7, Windows 8, or Windows 10 PCs with at least 512 MB RAM and 1 GHz processor.  In trunked radio systems, the APAA client software that resides on the dispatch console position (MCC7500 or MCC7100) operates on the same Windows OS used by the dispatch console. The trunking implmenetation of the APAA application also requires an Accountability server installed in the CEN network of the ASTRO 25 trunked radio system.  The Accountability server resides on the Enablement server virtual platform.

IP Technology
The Personnel Accountability application has the ability to interface to a customer's CAD application via an IP connection.  SDI requires the CAD application API information to interface to the CAD.  The Accountability server can also interface to the internet to retrieve radio alias configuration information from the EasyStaff website provided by SDI.
