+Vin (8-28 VDC) 2-Wire System: 8-28VDC 250mA max from external power supply. CAN H and CAN L communication
connected to the DCP.
4-Wire System: Connection from DCP/CANBus Splitter. Power supply is not required, as DAU LPBus will
receive its power from DCP/ CANBus Splitter.
It is recommended to use twisted pair wiring for CAN H and CAN L.

Green Pictogram Please Note: 2 outputs of 12Vdc or 24Vdc are
supplied with a max current of 20mA each. The
output voltage can be selected using the SW5
switch located inside the device (default: 12Vdc).
It is possible to connect any type of indicator that
doesn’t exceed these specications.

* - Only for contacts without voltage. Place an intermediate relay if any button has voltage.
** - In installations where the DAU is powered from a power supply that also has a battery backup, its internal battery may
be disconnected. In all other cases the battery should be connected, otherwise the system won’t work in the case of mains
power failure.
Note: Connections use a positive 5vdc common and all DAU programming is done via the DCP
End of Alarm (EOA): This indicates that the emergency lift trapping rescue is over and the alarm can
be turned o or reset.
Alarm Filter: The Cabin Alarm button will not activate unless the lift is in a fault condition or the
doors are closed, this lter is mostly used to prevent nuisance calls. DAU LPBus does not need to
be programmed but requires the lift signals.
Maintenance Alarm Button: This allows dialling of a dierent telephone number if a trapped person
is a member of maintenance sta (SOS number requires programming via the DCP, P030)
Cabin Alarm button: This is the main alarm button in the car operating panel which needs a voltage
free contact from the Alarm push to trigger an emergency Alarm call. The button is defaulted to
Normally Open, but can be recongured to Normally Closed (see programming guide DAU below
PC117)
LPBus (Low Power Bus): This connector allows the connection of Triphony and Inductive loop
units.
