CAUTION
Electrical voltage on lines
Risk of injury due to electric shock
● During mounting and installation work, electrical voltage must not be applied
to the lines.
Note the positive and negative poles.
Only connect one wire per terminal. This is the only way to ensure the connection
is failure-free for the entire service life of the device.

Two connection terminals are available for the aspirating smoke detector's power
supply. This allows more aspirating smoke detectors to be connected to a power
unit.
Prerequisite: The power unit used satisfies the requirements according to the
