FINAL CHECK OF AREA AND PRE-SETTING DECIBEL LEVEL
Again, use the most skilled people for wiring.
It is very important on a large job to check an area (approximately 30 units) before leaving it. Power the
area using one of the transformers. Power with an electric cord, with a plug on one end, and screw
connectors on the other end. Connect power cord to black wires of transformer. Hook wire from home
run to the two screws on the transformer and plug in. Use the sound meter to Test sound level. Find an
area near a Secondary where all of the ceiling tiles are closed to get a reading.
The ideal reading is between 47.5 and 48 dB. If this is not the level of the sound, adjust using the middle
volume control or if you have a CVC and all of the Mains were preset, you can do the final adjustment for
the whole area from the CVC. Allow to run for approximately 15 minutes. If the transformer overheats or
you can hear a loud humming sound, you have Incorrectly wired unit(s).
NOTE
It may be necessary for you to make 2 or more additional
trips to fine tune the project once the space is furnished.
