Compute X1 = h + w 1. X1 = 62"+ 55" (X1 = 117") 2. Compute X2 = 2d + w 2. X2 = (2 x 29") + 55" (X2 = 113") 3. Find X = minimum ( X1, X2 ) 3. X = 113" 4. Compute J = w + d 4. J = 55" + 29" (J = 84") 5. Find D = maximum ( X, J ) 5. D = 113" Where: h = Safe Height w = Safe Width d = Safe Depth D = Maximum Linear Distance This rule of thumb is valid for most available safe sizes. However, if any one dimension is very large or very small when compared to the other Table 6 Typical Safe Exterior Dimensions and Maximum Linear Distances Height Width Depth Volume Maximum Linear 25.00 21.00 21.00 6.38 46.00 32.00 25.00 25.00 11.57 57.00 42.00 31.00 29.00 21.85 73.00 52.00 31.00 29.00 27.05 83.00 62.00 31.00 29.00 32.26 89.00 62.00 55.00 29.00 57.23 113.00 64.00 31.00 29.00 33.30 89.00 72.00 35.00 29.00 42.29 93.00 79.00 43.00 33.00 64.87 109.00

A rule of thumb for estimating the maximum linear distance from the recommended detector location to any point on the protected surface is:
two dimensions, the safe may not follow this rule. In those cases, contact Potter’s technical support for assistance. Table 6 lists some common
safe dimensions and their maximum linear distances when detectors are installed in recommended locations.
