Notice!
i
The packaging for the multisensor detector with C sensor consists of tear-proof PE-ALU
laminated film and must be cut open carefully.
After installation and connection of the base, the detector head is set into the base and turned
to the right as far as it will go.
Detector bases are delivered with inactive locks.
The detector head can be locked into the base (removal protection). The locking feature is
activated by breaking the bolt (X) out of the base and pushing it into the corresponding guide,
as shown in , page 14 .
