Product Details

Viking’s model CTG-1A is a clock controlled tone generator designed to provide accurately timed bong alert tones or buzzer alert tone sounds over an existing paging system.

The CTG-1A can be programmed to output single, double or triple alert tones with up to 128 events in a 24 hour period in two separate schedules on a paging system. These bong/buzzer sounds are ideal for indicating the start and end of shifts, break times, lunch periods, etc. for factories, schools, or any business requiring an audible indication of specified times. Each day of the week can be programmed to either on or off, allowing you to turn off the alert tones during specific days of the week (weekends, etc.) In place of sending tones, the CTG-1A can be set up to operate a timed relay.

The CTG-1A has three contact closure inputs for triggering an emergency siren, evacuation signal or a doorbell sound.

Applications

  • Signal the beginning and end of class periods, breaks, and lunch periods for schools
  • Signal the beginning and end of shifts, breaks, and lunch periods for factories and other businesses
  • Provides a doorbell and/or alarm sounds over an existing paging system, for such applications as door entry, fire, severe weather, etc.
  • Use with Viking’s DVA-2WA to provide timed messages (DOD 110)
