FIX THE LCM INTO CEILING OR TO A WALL
Mounting the Intelligent LCM can be installed on the ceiling or wall-mounted.
Attach the Intelligent LCM to a flat, smooth surface.
The installation must meet all relevant building regulations.
The device wiring must comply with the requirements of the most recent IEE wiring
regulations (see BS7671).
Recommended mounting screws:
No. 8 (ø 4 mm) or No. 10 (ø 5 mm) screws with head diameter of 6 mm to 9 mm
Access and clearance
The installed Intelligent LCM and all connectors must be easy to access. Allow 300 mm
clearance (clearance = total height of the Intelligent LCM and connectors and cables).
Important: install clear of obstructions
Attach the Intelligent LCM downwards and clear of obstructions, such as ventilation shafts
and wiring ducts. The Intelligent LCM and connectors should be visible and accessible to
ensure easy connection and maintenance.

CONNECT DALI IN and DALI OUT
Connect the DALI line according to the system diagram.
Connect the DALI cable from the DALI subnet terminal of Helvar lighting router to
‘DALI IN’ on the first LCM-478 in the DALI subnet.
Connect DALI OUT of the first LCM-478 to DALI IN of the next LCM-478 in the DALI
subnet, and so on. No ‘DALI OUT’ connection is required from the last LCM-478 in a
DALI subnet.
Note: DALI is open topology , so a star or redial configuration can be used if required .
The maximum devices per subnet should not exceed the 64 devices or 250 mA.
Refer to individual device datasheets or contact Helvar technical support for advice
