5 Mounting / Installation
5.1 Required space
l When the point detector is inserted, the detector base is placed under stress by
compression, tension, and torsion. The fastening method must, therefore, be
designed accordingly.
l Detector bases must be placed flat on the ceiling.
l Avoid mounting on steps, concrete ribs, etc.
l Install the detector base directly on the recessed box or a level surface.
l If a surface-mounted cable feed is used, there are two possible break-out
points on the detector base for the cable entry. Max. cable diameter: 8 mm.
l The point detector must have at least 2 cm of free space to the side. Only then
can the point detector be removed with the detector exchanger DX791.
l Contorted detector bases complicate or even impede the insertion of the
detectors with the detector exchanger.
