Duct detector RCKD

Quick facts
• Smoke detector for installation in ventilation ducts
• Optical detector head
• Indication of a dirty detector head
• 0,6 m aluminium venturi pipe included
Use
Indication of smoke in ventilation ducts.
Design
Detector for installation in ventilation ducts, with optical
detector head, encapsulation and venturi pipe. RCKD
gives indication of a dirty detector head. Power supply is
from the control panel or control unit.
Material
Detector, white PVC with metal netting. Adapter housing
with lid for single tube detector, made of clear ABS.
Aluminum venturi tube.
Function description
The smoke detector has an optical detector head.
It also has an LED with two functions:
• red light indicates a tripped detector
(detector, encapsulation)
• dirty detector is indicated with a green light
(detector) or yellow light (encapsulation)
The detectors must be under continuous observation and
must be cleaned at regular intervals to avoid false alarms.
The detector head is easy to change thanks to its bayonet
fastening to the base. For detection in ventilation ducts,
the detector head is mounted in an adaptor. One venturi
pipe is then installed between the adapter and the duct to
lead ventilation air into the detector head. In this way, the
requirements for good fire protection can be complied with
air speeds of 0.2 to 20 m/s. At lower air speeds, an auxi-
liary fan must be used. A metal reed/plastic strip is fitted
for visual indication of flow through a duct detector.
Installation and location
Detectors are sensitive instruments, so care should be
taken with their location. They should not be located close
to sources of interference. The distance to the source of
interference should be not less than 3 hydraulic diame-
ters upstream or 5 hydraulic diameters downstream from
the source of interference. These distances are difficult to
maintain, so 2 and 3 hydraulic diameters can be accepted
in exceptional cases.
Duct detector RCKD is delivered with a 0,6 m venturi pipe
that can easily be shortened. When the duct is wider than
0,6 m the venturi pipe should go through the whole duct in
accordance to our mounting instructions. This requires a
longer venturi pipe, RBVR.
RBMD installation shelf is used for circular ducts and for
intact insulation of duct.
For location outdoors, in cold attics etc, the duct detector
should be insulated. If the detector is concealed, light box
RBLD should be installed.

Options 1 and 2
1. Install and join the damper in the ventilation duct that
ends at the wall or floor face (after the lead-through).
2. The damper is secured flat and tight using fire stopping
sealant (Intumex AN) against the wall/floor structure
with the fastening lugs, which are opened out.
3. Sealing is carried out by caulking with mineral wool,
min 40 kg/m3.
4. Use brackets to fasten the duct to the wall.

5. If fire damper is not connected to the duct system, fit
non-combustible grilles designed for the damper on the
unconnected sides. The minimum distance between
the damper blade in the open position and the grille is
50 mm.
6. Install the thermal sensor with the sensor body in the air
flow without obstructing the movement of the damper
blade.
