The sound is like a coaches whistle. The external gym horn provides several loud bells and buzzers where extra volume is needed. These horns can be provided wherever there may be excessive noise such as a high school weight room. Horn Set Shared Facilities Shared facilities such as gymnasiums or tennis courts may be scheduled so there is a specific time when the next group gains control of the facility. The CC8152 Timer can be used to schedule the change time and sound a horn.
Timers can be daisy chained together to control several courts on the same schedule.
