SM329 ANDON ALERT SYSTEM FOR PRODUCTION LINES
GENERAL DESCRIPTION The Andon alert system is a signalling system that allows production line staff to signal for assistance without having to leave their work station. The name ANDON has been adapted from the Japanese name for 'paper lantern', but it has become a common method of dealing with problems on production lines around the world. Most systems require expensive cabling over long distances, but the Alian system is fully wireless on VHF where stations can be up to 700 metres from a central administration area where a Display Panel can be observed by key support staff. This video takes nine minutes to describe the features and options of this system

STATION OPERATION (model SM329)
Each station has an identifying Station Number. This number appears on the top of each station and corresponds with a matching column of buttons on the main display panel.
Each station has a mains approved DC Plug Pack that needs to be powered by a nearby 240v power outlet. Stations also have a thin vertical rod antenna that it uses to send & receive wireless signals.
Stations have four coloured buttons, Blue, Green Yellow Red and Clear which represent four different departments within the plant. When any button is pressed, it will flash slowly to indicate a need for attention by the corresponding department. This action sends an alert signal to the main Panel where the matching button will also flash slowly.
Pressing the same button a second time will cancel the alert both at the station and the main Panel, and the lamp will turn off. It is possible to signal for attention from more than one department simultaneously
Where a lamp has changed to a steady glow, it is an indication that a support person has pressed the corresponding flashing button at the central Display Panel. This steady-glow is an acknowledgement signal to confirm that a support group is responding to the request.

THE CENTRAL DISPLAY PANEL (model SM330)
A typical Display Panel unit (shown below) is wall mounted. A 20 station panel is 110 cm wide and 22 cm high.
The illuminated buttons on such a system can communicate with up to 20 stations located in production areas.
10 Station versions are available.
When one of the operator buttons at a station are pressed, a corresponding lamp will flash on this panel. An announcing system built within the panel will sound a chime and say the name of the department that should respond to the request for attention. The volume of the voice announcement can be controlled via a volume control knob on top of the Central Panel.
Pressing one of the flashing buttons will trigger the verbal response “Confirmed” from the voice announcement system and change the lamp to a steady glow.
Back at the station that originated the request, the flashing lamp there will also be updated to a steady glow, indicating that someone has responded to their call at the Display Panel.

SM335 DATA LOGGER OPTION
An All-in-one desktop PC with a 1 TB storage drive and receiver unit may capture events taking place within the Andon system. A logging application has been developed so that every button press made at a panel or field station can be recorded as a time and date stamped activity that is added to a database file. Files are automatically archived when they reach a specified number of records. File formats are in generic Microsoft .mdb files that may be viewed with Microsoft Access or imported into a spreadsheet for further analysis.
SM335 EXPANDED DATA LOGGER OPTION
The expanded software set for the Data Logger system supports several additional features. Alert events may be extended to an in-house P.A. system so that voice messages or unique chime sounds can be heard throughout the site.
Event Management functionality has now been added to the data Logger suite, where various button presses surrounding a specific event are merged into a single detailed record, where a Reason code and additional description can be added to an event before it is sealed.
Large video screens are also supported where the current event will appear in large text on a video screen placed in a prominent location up to 50 metres away from the Data Logger computer. (Large screens can be any HDMI compatible display. A 65" screen is recommended)

LARGE SCREEN OPTION
Where a large display screen is to be attached to a system, most conventional TV monitors with a HDMI interface are suitable. Support for this is built into the Data Logger PC option.
It is usually logistically easier for the client to source their own screen locally, but a quote for a large screen can be provided upon request. Using a HDMI extender module, the screen may be placed up to 50 metres away from data logging PC.
Note: video extender & splitter hardware may be necessary for distant or multiple screens. Price of this hardware can vary and is available on application.
