Electrical connection
All work on electrical installations or equipment must only be performed by a trained electrician or by an instructed person under
the direction and supervision of a trained electrician in accordance with electrical engineering principles.
The maximum bus length is 250 m (loop length 500 m).
Each connected detector must be assigned a dedicated,
unique BUS address between 1 and 99. This is accomplished
with the PG 3.3 programming tool (accessory) The assigned
default address is 1. On request, Oppermann can configure the
detectors with custom BUS addresses (indicate in your order).
The positioning of addressed DKMs in the ringbus is arbitrary. A
fault alarm is triggered if the same detector address is assigned
twice on the ringbus. If the detector address is changed, the
detector must be reregistered with the STG in service mode.
