wall, or on a wall, between 4 and 6 inches from the ceiling. 

If questions arise regarding detector placement, it is extremely 

important that the drawings provided or approved by Siemens 

Industry, Inc., or by its authorized distributors be followed! The 

detector placements shown on these drawings were chosen 

after a careful evaluation of all facets of protecting the area. 

Environmental factors such as air current, temperature, 

humidity, air pressure, and the nature of the fire load are 

carefully considered. Special consideration is given to room or 

area configuration and the type of ceiling (sloped or flat, smooth 

or beamed). Siemens Industry, Inc.'s extensive experience in 

the design of fire detection systems assures optimum detector 

placement and is reflected in these drawings. Follow sound 

engineering judgment made by qualified personnel.
