Alarm Dispatcher calls the emergency services of authorities and organizations with security tasks, such as fire departments, technical rescue services, rescue services, police, water rescue, security services, but also hospitals and private companies, and allows feedback on whether the user is participating in the operation or is prevented. Each user is assigned his functions, so that it is immediately visible whether sufficient specialists will be available or whether further emergency services need to be alerted. The Alarm Dispatcher App comes pre-configured and with personal support so that users can concentrate on extinguishing, rescuing or protecting rather than on the administration of IT systems. Alarm Dispatcher is a data protection-compliant solution for the transmission of operational data on smartphones. Each organization decides for itself which data it displays in the app. In the standard version, personal data remains in the offices of the organization, while only the deployment keyword and district are transmitted, but an alarm can also be sent completely without deployment text. Managers can receive more information. As alarm input the Alarm Dispatcher Box is used by the organization. It processes signals from digital and analog radio message receivers, fax, e-mail, SMS, calls, Twitter, control center systems, etc. On the deployment monitor at the Alarm Dispatcher Box, the complete deployment information is displayed and enriched with feedback and map material. It is also possible to print out the assignment with the Alarm Dispatcher Printer. ADVANTAGES Complete solution The well-proven complete system saves the purchase of a PC and other hardware. Everything is delivered completely installed. The customer sets up the alarm dispatcher system and is ready for use. 24h monitoring Emergency services need sleep - our monitoring system does not. It ensures that every alarm dispatcher system works reliably and informs the customer if there is low radio reception, power failure or an update is pending. Personal contact Adaptation requests, questions about configuration and function, on-site appointments or help with acquisition? We provide support until everything is set up and beyond that at any time by phone, e-mail or, if required, on site. Simple price model One-time hardware costs and low running costs, completely independent of the number of operations. With us, there are no intransparent package prices or limits on the number of users - because only transparency creates acceptance. FUNCTIONS - Real-time deployment information on the smartphone in compliance with data protection regulations - Feedback from the emergency services (yes, no, later) - Appointment management and duty scheduling - Representation of the available emergency forces according to function groups - Loud alarm also in sleep mode - Feedback directly in the lock screen - Membership in several organizations possible - Organization management completely in the app - SMS alert for users without smartphone Behind Alarm Dispatcher is a German team of experienced emergency services from various aid organizations, developers, testers and legal experts. Due to our customers in the most different fields of application, the Alarm Dispatcher system helps in the meantime both technical relief organizations with few operations per year and professional fire departments in large cities with complex redundancy systems and a large number of operations per day. This flexibility to adapt to the different requirements of the relief organizations and to make individual adjustments is something our customers appreciate.
