Disposal

Unusable electrical and electronic devices or modules must not be disposed
of with normal household refuse. They must be disposed of in compliance
with the applicable regulations and directives (e.g. WEEE in Europe).

Packaging film for the FAP-OTC 420/FAP‑DOTC420
The packaging bag used for multisensor detectors with C sensor consists of tear-resistant PE-
ALU laminated film and may be disposed of with the household refuse.
Defective detectors are exchanged and should be disposed of in accordance with legal
regulations.
