Upon insertion of the detector, the detector base is stressed by compression,
tension and torsion. The fixing must thus be designed accordingly.
Detector bases must be placed flat on the ceiling.
Avoid mounting on steps, concrete ribs, etc.
Install the detector base directly on the recessed box, or together with a base
attachment, when the supply lead is surface-mounted and the cable diameter is
more than 6 mm.
There must be at least 50 cm below and at least 2 cm of free space to the
sides of the detector, so that the detector can be removed or tested with the
detector exchanger and tester.
Contorted detector bases complicate or even impede the insertion of the
detectors with the detector exchanger.
