Remarks

Note: Settings for electronic IDMT relays are generally software set. Therefore the maintenance test of electronic IDMT relays may be reduced to a check that the commissioning settings have not been changed, or the network (protected by the IDMT relay) has not changed, which would require a re-commissioning of the IDMT relay. The manufacturer’s data sheet should be used in all circumstances

Complete Groups of luminaires are assigned to the correct positions in grid switch or grid

single circuit dimmer

Emergency lighting complies with recommendations of BS 5266/BS 12464-1 Luminaires and remote control gear are of the correct make and type

Fixed luminaires have been installed at the correct orientation Fluorescent lamps have the correct phosphor

Lamps are of the correct colour temperature (Rendering Index Ra **) All lamps are the correct wattage and voltage ratings

Exterior floodlights have been aimed to drawing and according to terms of planning permission

Horizontal illuminance on horizontal tasks(s) is at specified level Vertical illuminance on vertical tasks(s) is at specified level PIR detector systems are programmed and operate correctly Lighting levels associated with control signals have been chosen

When commissioning lighting installations, grouping rooms with similar functions and lighting designs, for example toilet areas may reduce the number of repeated tests.

A more comprehensive lighting commissioning schedule is available from CIBSE
