Description:
The Plena Weekly Timer is a precise, versatile timer system designed for use in public address systems, particularly in environments like schools, shopping malls, and venues requiring scheduled messages, signals, or other controlled events. It is well-suited for integration with the Plena Message Manager and Voice Alarm System, making it ideal for complex scheduling needs.

The unit features two separate weekly schedules, with the ability to assign multiple events to each minute of the day. Each event can trigger different actions, including playing chimes, controlling the output contacts, or adjusting background music levels. Events can be programmed and controlled via the front panel, USB connection, or RS-232 for syncing with external displays.

Key Functions:

• Weekly Scheduling:

  • Program events for each minute, with separate schedules for each day.
  • Choose between two independent schedules, selectable via the front panel.

• Event Triggers:

  • Each event can trigger one or more of the following:
    • Chimes: 14 different chimes available.
    • Contact Outputs: Six programmable contact outputs (open, close, or pulse).
    • BGM Volume Change: Adjust the background music (BGM) volume to a preset level.

• Clock Synchronization:

  • Automatic synchronization with an external clock or PC via USB.
  • Supports synchronization with a time server and maintains accurate date and time.
  • Automatic switching between daylight saving time and standard time (based on European, North American, or user-defined dates).

• Battery Backup:

  • Includes a 24V backup power input with reverse-polarity protection, as well as a battery to preserve the correct clock settings during power outages.

• Audio Input/Output:

  • Includes an audio input and output for controlling background music signals.
  • The volume can be set manually or programmed to change at predefined times (e.g., lowering the music volume in the morning and returning to a normal level later).

Connectivity:

• Line Input: 1 x XLR balanced connector (sensitivity 1 V, impedance >5 kohm).
• Line Output: 1 x XLR balanced connector (impedance >100 ohm).
• Output Contacts: 6 programmable contacts (100V, 1A, voltage-free).
• Clock Sync Input: Contact closure synchronizes to the nearest hour.
• USB and RS-232 Ports: For synchronization, programming, and connecting to external devices (like large displays).

Controls and Indicators:

• Front Panel:
  • Display of current time, scheduled events, and program status.
  • Buttons for controlling event triggers, contact outputs, and BGM volume.
• Synchronization and Programming:
  • Sync time with external sources via USB or manually configure events from the front panel.
  • RS-232 connector available for large display connections.
