General notes for all sensors 4 If the sensors are to be concealed (e.g. in false ceilings, shafts etc.), mark their locations visibly and record them in the site documentation. Fix a labelling plate in the direct vicinity of the sensor. This must include a plain text description and the reference number, which appears in the plant schematic. Do not attach the label to the device itself.
