Duct Smoke Detector KRM
6 | 9 | Fire Protection | Data sheet No. 41300 | Version 06-2012
Installation
1.
Drill a hole 43 – 44 mm in diameter at the intended mounting location.
Note: Installation of the TurboTube measuring tube is possible either from
the top, bottom or side of the channel for all duct
cross-sections (for round ducts as well).
2.
• Determine how long the measuring tube must be.
• If necessary, shorten the tube. Minimum length 160 mm.
• Deburr the cutting face and put the end plug back on up
to the stop collar.
Note: Depending on delivery batch, either the transparent end caps
displayed here or black end caps with a slightly dierent geometry will be
included in the delivery.
3.
• Determine the direction of ow and t the adapter plate so that
the line on the adapter plate under the text ”Strömungsrichtung” is
parallel to the ow direction.
• Four self-tapping screws serve for attaching it to the sheet metal
duct (not included in delivery).
4. Installation on a rectangular air duct
• see picture at right
5. Installation on a circular air duct
• For mounting on a circular air duct use mounting bracket type KS
and the rubber bushing
. Thanks to the bend
perforations they can be adapted to a round duct.
The type KS mounting
bracket is supplied at.
6. Installation on air ducts with insulation
• Use the rubber bushing and insert it into the ø 43 – 44 mm
open ing in the air duct.
• Install the mounting bracket.
• Insert the assembled adapter plate into the measuring tube by
sliding the measuring tube through the grommet, and screw the
adapter plate onto the mounting bracket using the 4 self-tapping
screws. Then the insulation can be installed.
7. Installation outdoors or in a cold environment
• As protection for smoke detectors which are exposed to the open
air or in a cold environment there is a special WDG type splash-proof
housing. This enclosure prevents the warm air in the smoke detector
duct from condensing.
The interior of the housing is insulated with
foam rubber.
