Det-Tronics U5005 Smoke Detector - Manual (Page 4)

MAINTENANCE
Regularly scheduled maintenance is normally not
needed, however, periodic cleaning of the smoke
chamber may be necessary when detectors are located
in abnormally dirty or dusty environments. Vacuuming
around the smoke chamber housing prior to blowing out
the chamber with a “dry air” hose is recommended.
NOTE
The U5005 is not designed to be serviced or
repaired in the field. Disassembly of the detector
in the field will void the warranty. If service or
repairs are required, return the entire unit to the
factory.
The smoke detector can be tested using the same
methods employed for any photo-electric detector.
We recommend using canned smoke for periodic
maintenance of the detector.
DEVICE REPAIR AND RETURN
Prior to returning devices or components, contact
Detector Electronics so that a Service Order number
can be assigned. A written statement describing the
malfunction must accompany the returned device or
component to expedite finding the cause of the failure.
Return all equipment transportation prepaid to the
factory in Minneapolis.
