The coverage area is strongly dependent on the
material of the object to be monitored. Based on
practical experience, an effective radius of r = 5 m
applies to steel and iron-reinforced concrete.

Coverage area
Ideal coverage area
To achieve the ideal coverage, do the following:
• Install one detector for each plane (walls, floor, and
ceiling) of the protected area.
• Do not add the coverage from adjoining planes to the
comprehensive protection strategy.
Coverage area reduction
The operating radius and the coverage area can be
reduced by:
• Tightly sealed corners and edges
• Incorrect positioning
• Interstices
