Overview Program the whole year ahead of time with this flexible Redback A4510B yearly school timer. Easy to use software allows the installer or end user to program school term dates, student free days, public holidays, day light savings for the entire year. It can be configured for either weekly or fortnightly time tables and interfaces with the school PA?system for automated messaging, bell, prebell and music. The timing events are programmed with Windows based software featuring a user friendly calendar layout. This can also be programmed remotely over a local area network (LAN) using a serial to ethernet adaptor (A4498). The Micro SD card supplied, stores all the MP3 files and timing event programs. The prebell and music outputs can be setup for random play of MP3 files for Call to Class playback of music. When a timing event is activated, an MP3 audio file will be played and output through the dual RCA line level output. There are 99 audio playback options for the timing events, which include the Bell, Prebell, Music and outputs 5-99. A Micro SD card which is supplied, houses all the MP3 files to be played as well as storing all the timing events (Note: The audio files must be in MP3 format). The Prebell, Music and outputs 5-99 can be setup for random play of MP3 files, making the unit ideal for Call to Class playback of music which changes each time these outputs are activated. The events when activated also trigger the 24V outputs available on the rear of the unit. Separate 24V DC outputs are available for each of the Prebell, Bell and Music outputs, as well as a common 24V DC output which is activated for all output conditions. The timing events can also be programmed to trigger the Bell 24V out (and in turn the common 24V Out), with no audio output for activating an external bell or siren. The unit features Daylight Savings mode which when activated automatically adjusts the clock time by one hour at the user programmed dates. The internal clock has a battery backup (CR2032 supplied) in case of power failure. (Note: This will only backup the time, it will not power the unit in the event of a power failure).
