The Plena Weekly Timer is an accurate timer for use in public address systems. It is ideally suited for schools, shopping malls and all other venues that need regularly timed messages, signals or other controls. It is ideally suited for connection to the Plena Message Manager and Voice Alarm System.
  • Two weekly programs
  • 14 Chimes
  • Six contact outputs
  • Automatic summer winter time
  • BGM level control
  • Hold and pause function
  • Programming on the unit and via the supplied PC program
  • Ideal partner for the Plena Message Manager and Voice Alarm Controller for timed messages
The unit has an audio input and output to attenuate BGM signals. The volume can be controlled directly from the front panel, or programmed to change level at fixed times, for example, to automatically attenuate music in the morning or evening hours. It can automatically jump back to the programmed level at the next event.
The timer has a clock sync input to synchronize the time with an external source but can also take the correct time from a PC. This way it can synchronize with a time server. The timer clock also keeps track of the date, ensuring correct weekday display and automatic summer winter time setting. (according to European, North American, user defined dates or off). The timer has a 24 V backup power input with reverse-polarity protection as well as a back up battery that preserves the correct clock setting.
Synchronization and programming is done via the USB port. Programming can also be performed by the front panel. An RS-232 connector is available to connect to a large separate display.
The unit has two weekly schedules as well as a pause mode, where all actions except the clock display are suspended. Events can be programmed with a accuracy of one minute. There is no limit to the number of events, every minute may have an event associated with it. Each day can have a separate event set, and two schedules can be programmed. The schedule can be selected via the front panel. Each event can trigger:
  • A chime
  • Any combination of output contacts
  • BGM volume change
The timer can broadcast 14 different chimes via the audio throughput. It has six programmable output contacts with relays to connect to other equipment. Programmed contact events can open or close the contact or generate a pulse of configurable duration. The contacts can also be controlled via buttons on the front panel.
