Description 

  

 

These 25/70-volt Lay-In Ceiling Speaker assemblies 
provide a quick and easy solution to speaker installations. 
The S-422

A-2

 and S-522

A-2

 are complete speaker assemblies 

including baffle and back box. This integral design meets 
or exceeds ASTM E84 Flame & Smoke Test with a 3-
hour burn rating (UL 181), which allows this integrated 
package to be used in plenum type drop ceilings. 
 
Several inputs are provided on the S-422

A-2

 assembly to 

provide the proper volume level when used in different 
acoustical environments. The S-522

A-2

 assembly provides  

rotary tap volume control accessible from the front on the 

speaker. Both of these assemblies are well suited to be 
used in classrooms, offices, meeting rooms and other 
applications where high quality sound reproduction is 
required. 
 
Both the S-422

A-2

 and the S-522

A-2

 eliminate the mess  

and 

broken tiles that often accompany installations using 

standard speaker assemblies. These dynamic all in one 
packages eliminate cutting circular holes in tiles, 
mounting backboxes and mounting speaker grilles to 
backbox assemblies. The white finish of the 

perforated

grille blends easily with most

 

décors and provides an 

unobtrusive speaker installation.

            This literature does not cover all the variations in the equipment described, nor does it provide for every possible contingency to be       

            met in connection with installation, operation, and maintenance.  All specifications and listings are subject to change without notice. 
  

 

 

  
 

For installations in a 2’ x 4’ ceiling grid, an optional trim bar  
(V-TBAR*) may be ordered.  The V-TBAR provides support  
and a finished appearance to one edge of the speaker grille. 
 
These assemblies are also an excellent choice for all applications 
requiring intercom capabilities. They are specifically designed for  
applications involving the 5100 Communications System to provide  
superb talkback quality. 

 
*The V-TBAR is available separately and must be ordered in packs of 10. 

NOTE: The S-422A-2 or S-522A-2  

is a single unit, but must be ordered in 

quantities of two
