Multi functional  Public Address System, made easy.

It's made in two main parts: 

Software:  Jo Tech Service. PA program,  xp , USB version

Hardware:  Advantech co. Ltd.    Industrial automation rail mount USB interface with 48  digital I/O  and a terminal board with 24 opto insulated  inputs + 24 relay outputs.

Schematic example 1:   Using an industrial rail mount USB interface and standard amplifier racks.

Schematic example 2:   Similar with a different interface and standard amplifier racks.

Schematic example 3.   A Norwegian coastal passenger & cruise ship is now using this solution. :   Simple interface to add our PA System to an intercom or telephone system,  connected as a station with programmable direct access keys.   

A typical user panel.

Select pre recorded voice alarm / message, then push the button. Led will indicate status.

Separately Addressed Pre recorded Announces  / Spot Announcing Machine, Separately Addressed Microphones,  Separately Addressed Pre recorded Emergency Voice Alarms, Separately Addressed Pre recorded Messages, Addressed Program Distribution.   This program , a PC , Advantech USB-4751 48 x digital I/O + I/O terminal board, PA amplifiers , speakers, microphone panels, firemans alarm panel, outputs from critical alarms, local panels to activate pre recorded addressed messages and a program source for addressed background sound, makes a professional and cost efficient PA system for public areas like airports, ferries, railway stations, schools, passenger & cruise ships, stores, super markets.    

PC program w / ID and support : 1000Euro

 *

Separately Addressed Microphones , this function invokes an advanced programmable pa group controller . 
Security microphones and Firemans alarm panel have highest priority. Microphones are not logged .  

Separately Addressed Pre Recorded additional Voice Alarms. 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 Addressed Pre Recorded Messages   are activated by "the message selector and the message start button" in local panels . As an example: by taxi drivers / bus drivers / tourist guides.     Messages are not logged and have separate priorities like alarms.

Separately Addressed Fixed Messages / Weekly Controller with 21 fixed messages with  separate distribution addressing. It also control the announcing start / stop function . Priority belowe microphones, alarms and 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.    30.000 output address patterns are available in this function. The digital outputs are used to control speaker lines and relay connector 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, indirectly controlled 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. 

*

The free USB demo version  have most primary functions included Digital IO enabled, with exeptions for a save option of userdata , also the number of announcing files, announcing system and the use of hardware setup is restricted.     This program can run withouth  the USB adapter, but expect an error message.

Note!   This is an US version.   Before starting this program make sure Windows global setting is correct .

Note! Control panel / Global settings : Region / Language = English(USA) , ( Timeformat :  with AM/PM )

Latest update of the demo USB version : may 06/2009 .  

announcedemo.exe and catalog.dat are the latest updated files.

The program can run withouth  the USB adapter, but expect an error message and the  program stability not to be 100%.

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.

"Free Audio Editor" is highly recommended .

As an example, the setup of this update will invoke "Audacity" wav file editor .

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

Audio file type = *.wav  

Audio file directory :   \announcedemo\sound  

Audio editor : options > catalogs >  \programfiler\audacity\audacity.exe  (  or make  new directory  )

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

PA controller / add on

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.

Announcing System , Alarm & Extended I/O Manager ( US-Ver. ) is one program we made from this idea .

Some of the specifications:  

USB version: XP tested ok

If a raid diskcontroller and doubble harddisks are used, this system will be nearly failproof.    

Mediafiles as Announcements, Gong signals, Alarms and Messages of any kind are all stored as wavefiles on the harddisc .  

Easy to implement external voice alarms or signal alarms ( abadon ship, genaral alarm, fire )

Userfriendly extended Mediafile Recorder / Function Composer .  

User Guide made as Online help .  

Number of mediafiles has in practice no limit in this program .

Number of output address patterns has in practice no limit in this program .

No tape to organize .   Windows file control is used in this program.

A standard  multimedia controller interface   makes recording , playback and file control  easy.

Easy to use announces playlist with repeat and auto update.  Separate announces start and last dates makes an automatic control  and update of the playlist .  If the date is :   Before the announce start date the announce is skipped ,  Inside the start and last date the announce is played and    After last date the announce is removed from the playlist .  This function also make it easy to compose and place announces in the playlist days, weeks, months and even years before their separate start dates. To be played more often an announce should to be placed several times in the playlist.

Detailed Weekly fixed messages and announcement controller . 21 fixed messages with separate output routing, 3 different gongs ( open - preclose - close ), separate weekday announcing ON/OFF controller , separate weekday announce start/stop function fully adjustable with accuracy set to 1 second .  

Easy to use Announces sequence controller with accuracy set to 1 second .

All timers used are software timers controlled by the program itself and some of them also by the user.  These timers have a programable range from 1ms and up with high accuracy. Some timers are free running and others are controlled by the PC's time & date .

Controlled autoerase after Last Date prevent the harddisc from being filled with old files.  

Mediafiles are activated by different programfunctions , I/O inputs etc.  

Input priority in maximum 48 levels .  

Alarminputs with eventlogg to file, separate alarm message repeat control, priority control and more.  

Maximum number of groupnames controlling digital output patterns are 32767, but restricted in demoversion.

Mediafiles gives indirect separate function control of digital outputs .  

Microphone gives indirect function control ( Top Priority,  announces sequence controller paused, output lines routing ) .   

Mouse gives direct function control by click or doubbleclick on buttons .  

User can easily make mediafiles and compose functions related to them .

Advanced function,  simple hardware and low total price.
