INTRODUCTION
1. The Digital Audio Unit (AC-DAB10-120-F-0L-000) connects with the Digital Communication
Platform (DCP) to provide a 2-way communication point in the lift car.
2. The DAU is mounted behind the lift car operating panel (COP) and connected to the machine
room mounted DCP via a 2 or 4 wire digital CAN Bus, providing stable communication over
trailing cables of up to 200m.
3. The DAU can be installed with 2 or 4 wires: 2 wires uses CAN H and CAN L to reduce interference
problems with the DAU LPBus and requires an external power supply between 8-28VDc 250mA,
while 4 wires means no external power supply is needed because the DCP will supply the power
required by the DAU LPBUS.
4. It is recommended that customers use shielded twisted pair cable to ensure minimal disruption
to the audio channel from ambient electrical noise in the travelling cable.
