3.13. Powering Up
After the Whistle or Tweeter is connected to its device, it is ready to be powered up.
Caution:
Before applying power, ensure that the DC supply is within the specified range
and that the proper plus-minus connections are in order.
3.14. Initializing the System
After the Whistle/Tweeter has been connected and mounted, the system must be set up and
initialized. This is accomplished using the Composer, Elmo’s Windows-based software
application. Install the application and then perform setup and initialization according to the
directions in the Composer Software Manual.
3.15. Heat Dissipation
The best way to dissipate heat from the Whistle is to mount it so that its heatsink faces up. For
best results leave approximately 10 mm of space between the Whistle's heatsink and any other
assembly.
3.15.1. Whistle Thermal Data
• Heat dissipation capability (θ): Approximately 10 °C/W
• Thermal time constant: Approximately 240 seconds (thermal time constant means that
the Whistle will reach 2/3 of its final temperature after 4 minutes)
• Shut-off temperature: 86 °C to 88 °C (measured on the heatsink)
