Equipment must be solidly mounted.
When detectors are inserted, detector bases are subject to pushing, pulling and shearing
stress and must be mounted accordingly. There must be at least 50cm free space be-
neath the detector for test purposes.
Detector bases must lie flat on the ceiling (do not mount on bumps or hollows, concrete
ridges etc.).

Fire detectors must be easily accessible for regular servicing.
The response indicator in the base must be easily visible from the alarm investigation
route.
