Caution:

  

Do not bring conduit through the rear of the electrical box. 

 

1.  Tighten mounting screws snugly (do not overtighten). Torque mounting screws 5-7 in/lbs. 

2.  For flush mounting, install the box either flush with the ceiling or with a maximum ¼-inch recess. 

 

 

 
 
 
 
 
 
 

 

 

 

Notes:

 

1. 

The TrueAlert Ceiling-Mount A/V attaches directly to a 4-inch square electrical box (not supplied), semi-flush or surface mounted. Ensure 
correct orientation of the box in relation to the location of the mounting screws and the A/V’s position. 

2. 

For installation in a concrete or plaster ceiling, flush-mount the box (with a ¼-inch recess, maximum). 

3. 

For installation in a suspended ceiling, use a suitable tile bridge that rests on tile to support the box.

 

4. 

Address Switch SW1 is accessible with the Ceiling-Mount A/V removed.
