Emergency Broadcast Systems

Emergency Notification Systems This section of our technical library presents information and documentation relating to Emergency Notification Systems and Disaster Recovery Applications. If a severe snow storm hits your area, your community can be notified of school closings or event cancellations. Should an emergency arise in your community, our emergency broadcast phone service can deliver large volumes of phone messages quickly using thousands of digital and analog phone lines simultaneously. If a dangerous chemical spill occurs in your community, you can target specific areas to call. In the event of a blizzard, wild fire or devastating flood, your community can be notified quickly given specific instructions if an evacuation is required using our emergency broadcasting service.

AcsAPI Library Routines - Connection


    int ACSConnect(const char * hostname, const HWND hWnd);


    int ACSConnect(const char * hostname);

    These return the IP Address of DscACS (via asynchronous response ACSAPI_RT_CONNECT), used for later threaded uploads of waves and phone lists.  The return code is an integer representing the context of the connection, used in subsequent calls (Windows), or a success return code.  For all routines below, add a preceding argument of “const int context” on all calls from a Windows application - for example:

    Windows (AcsApi32.dll):            int  ACSLMGRStart(const int context,

    const char * _campaign);

    Unix (                   int  ACSLMGRStart(const char * _campaign);

    (The only exception to this is ACSDecode(), as it does not communicate with the DscACS service.)

    void ACSDisconnect();

    int ACSDecode(const char * message, void * structure);

    int ACSPing();

    int ACSPong();

    int ACSMessage(char * message);

Tornados - Emergency Dialer for Tornado Warnings

civil alert tornado warning If a tornado should threaten your community, our emergency warning service can contact your neighbors quickly. With our emergency notification phone service, you can broadcast warning messages to thousands of households in your community warning of catastrophic disasters including tornados and high wind storms.

Messages can be simultaneously delivered in just minutes using our network of phone systems and services. Pre-recorded warning messages can be played giving households information regarding the tornado and storm location and whether a community evacuation is planned or necessary. You can send a broadcast warning to specific neighborhoods or communities in the event of a tornado and provide priority delivery of these messages to those households that are in the immediate path of these storms.
