## Long description

Cover for Smoke Detector Nedis DTCTDUST20 is a protective dust cover designed for smoke detector devices compatible with Nedis. It shields the detector from dust and contaminants while maintaining access to the device and preserving its basic functionality. With outer dimensions of 140 × 127 × 23 mm, the cover is suitable for temporary protection of detectors in residential or commercial environments during maintenance, renovation or storage.
Advantages

Its simple shape fits common detector housings that match the stated dimensions.
Suitable for
 Temporary protection of Nedis-compatible smoke detectors during painting, renovation or construction
 Covering detectors during cleaning or dusty maintenance tasks
 Short-term storage or transport of smoke detectors to reduce contamination
When it may not be suitable
This cover is intended primarily as a dust shield and does not replace functional protective devices required by local safety regulations. Do not expect it to provide waterproofing, impact protection, or long-term environmental sealing. Also ensure the cover dimensions (140 × 127 × 23 mm) match your detector model before purchase.
Key specifications

How to use

Use the cover only for temporary protection and store it in a dry place when not in use.
