reduction in the transferred signals to adjoining surfaces such as coverage from a wall-mounted
detector extending to the adjoining wall, ceiling or floor, is not depicted.
As construction methods of vaults may vary, the transfer of detection radius from one
surface to an adjacent surface should not form part of any calculation.
Figure 6-17: Example 2 - detector location and detection radius
Using a scale drawing of the room to be protected and adding the detection radius is a
good method of verifying a system design.
