5 Mounting / Installation
5.1 Required space
● Upon insertion of the detector base and sounder base, the detector base is
placed under stress by compression, tension, and torsion. The fastening
method must, therefore, be designed accordingly.
● Detector bases and sounder bases must be placed flat on the ceiling.
● Avoid mounting on steps, concrete ribs, etc.
● Install the detector base or sounder base directly on the recessed box or a
level surface.
● If a surface-mounted cable feed is used, there are two possible break-out
points on the detector base or sounder base for the cable entry. Max. cable
diameter: 8 mm.
● 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.
● Contorted detector bases or sounder bases will complicate or even impede the
insertion of detectors.
