Separately AddressedPre Recorded additional Voice Alarm Messages. T here are multi priority inputs in 1 to 24 levels with shown hardware ( max 48 levels available ), all alarms are logged, all inputs have separate messages, separate adjustable alarm message repeat and separate groupname to control the Public Addressing and critical  relay outputs.   The alarms are activated via direct inputs from other alarm devices or by "the alarm selector and the alarm start button" in local panels .  This function have priority above the announcing machine.  

Separately AddressedPre Recorded info Messages  are activated by "the message selector and the message start button" in local panels . As an example: by the reception / bus drivers / tourist guides .   Info Messages are not logged and have separate priorities like alarm messages.

Separately AddressedFixed Messages / Weekly Controller with 21 fixed messages with  separate distribution addressing. It also control the announcing start / stop function . Priority belowe microphones, alarm messages and info messages, but above announces.

Separately Addressed Announces  / Spot Announcing Machine.Every announce has it's own data file with separate address data and start / end date.   Priority in lowest level.    32767 output address patterns are available in this function. The digital outputs are used to control speaker lines and relay outputs

Addressed Program Distribution :Addressing of this function is controlled via group named "Background" and have no priority.  Program audio is connected to aux input on the amplifier's. A muting circuit controlled by the PC  program and external inputs is used to cut the program source while other functions are active.

Manual Address Preset Output Panel / Program ON/OFF.   1.  If any I/O input is active : "Program " = OFF.    2. If "I/O output 47" is active : "Program " = OFF    3. If I/O output 48 is active : "Manual Address Panel " is disabled.  

Free relays can be used as separate output logic, indirectlycontrolled by I/O inputs via an output address pattern ,  indirectly controlled by a fixed message or indirectly controlled by an announce.    

Verified input address values . Two equal I/O readings with a 0.25 sec. timeslot, is necessary to activate any Digital I/O input. This function  is implemented to avoid phantom calls.

General notes:  After connection or reconnection to another USB port, exit the announcing program , turn the PC off , then restart the PC . When using an USB expander it must have external power supply.

Setup and Function test: use Advantech Device Manager

About: This ( USB / XP ) program version was written in Visual Basic ver. 6 . 

Original program version was written in VB3 ( year 1995 / ISA / Win 95 )

****************************************************

It is  now possible to invoke  any  external wav file editor to make gong files, fixed announces, alarm  audio files and also to repair  or remake announcing audio files.

" FreeAudioEditor "  http://free-audio-editor.com/   is highly recommended .

Others :   http://audacity.sourceforge.net/download  

Audio file type = *.wav  

Audio file directory.    Example:   \ann1vb6\sound  

Write the path to your Audio editor .  Example :  options > catalogs >  \programfiles\audacity\audacity.exe

A good wav file editor with noice reduction is a must while using our spot announcing program.

Program filosofy.

We make software to combine  standard Industrial I/O cards and a multimedia PC .

The idea is to make the use of low-cost  , massproduced industrial I/O cards in conjunction with a multimedia PC easy , yet powerful and flexible. Such programs make the PC become a controlcenter that opens for new, extended use, in a wery easy way.

Our advanced multi functional Public Address System  ( US-Ver. ) is one program we made from this idea .
