Global Technical Assistance Center's services are provided on a time and material basis or through a Solutions Enhancement Support Program (SESP) contract. Users can reach the centers through eSupport or phone. They are either directed to an available engineer at a Technical Assistance Center or their contact information is captured and shared with an engineer who returns the call within an agreed response time. Calls are prioritized based on a number of factors, including criticality of the event and impact on safety and the environment as well as contractual response commitments.
Additionally, Global Technical Assistance Centers provide information through the Honeywell website like the Information & News Tips newsletter for SESP users, critical problem notification for affected users, retrofits announcement letter for all users, B-Aware advisories for SESP users and P3/CWS TAC alerts for P3/CWS Field Service Organization.
