Mounting the CS 120P in a Suspended Ceiling

1. 

Disconnect power  — Power down all attached devices.

2. 

Verify the space where the CS 120P will be installed  — Ensure that there is sufficient clearance above the ceiling tile 
for the CS 120P to rest on top of the tile.

3. 

Configure the CS 120P for a U.S. or metric ceiling  — For U.S. ceilings (2 feet by 2 feet or 2 feet by 4 feet), leave the 
four tabs on the side of the CS 120P intact. For metric ceilings (600 mm by 600 mm or 600 mm by 1200 mm), cut off the 
tabs.
