INSTALLATION MANUAL
Addressable Device

This Duct Detector Housing (DDH) is designed to provide capability to mount the indicated Aurora / Vega smoke detector. When installed correctly
it will then allow monitoring of airflow in heating and ventilation ducts for fire combustion products. The DDH must be fitted with a Aurora conven-
tional / Vega intelligent smoke detector linked to a compatible control panel and a suitable sampling tube installed as shown. DDH has been de-
signed to allow optimum airflow through the detector and it is recommended for installations in ducts with low airflow and with an air speed be-
tween 0.5 m/s and 20 m/s.
CHARACTERISTICS
-Easy to install
-Installer friendly cabling
-Simple servicing and maintenance
-Single tube air sampling system
-Sampling tube with innovative design
-Sampling tube easy to mount
-Test hole positioned on cover.
Compatible detectors: TI-002265 (Aurora smoke detector)
V100 (Vega smoke detector)
The air sampling tube is supplied in three lengths: 0.6 m (DDH-ST0.6)
1.5 m (DDH-ST1.5)
2.8 m (DDH-ST2.8)
If the ventilation duct is wider than 0.6 m the sampling tube should
penetrate the whole duct.
Mounting bracket (for insulated / circular ducts): DDH-BR
Weight: 660 g (without the detector installed)
INSTALLATION
The sampling tube is made of aluminium and can easily be shortened
to suit the diameter of the duct.
With insulated or circular ducts use the DDH mounting bracket.
MOUNTING AND POSITIONING
The DDH can be installed on any side of the duct.
We recommend that the DDH is mounted at a proper distance from heating, cooling, humidity or similar devices, equal to the positioning standard
of flow meters.
A distance of 3 times the duct diameter should be left before a damper, filter or change of the duct direction.
A distance of 5 times the duct diameter should be left after a damper, filter or change of the duct direction.

1Drill a hole in the duct:
-Without bracket, ø 38 mm.
-With bracket, ø 51 mm (see point 10).

1. Measure the diameter of the duct.
2. Shorten the pipe, if necessary. The pipe should penetrate
approx. 90% of the width of the duct. NOTE! See point 9.
3. Insert the end plug.
Do NOT cut this end!

2. Secure the bottom of the DDH with the three provided screws; screw positions
are marked on the picture.

ELECTRICAL INSTALLATION
2. Use a cable gland (PG13.5 or M20). The DDH is factory prepared
with one cable opening. In case more than one opening is
needed, carefully remove the round plastic wall in the selected
entry and insert a cable gland. If the factory prepared opening is
not used, it must be properly sealed.
Ensure all glands are fully sealed and no openings remain to
allow air leakage which may prevent effective operation.
1. Remove the cover over the DDH (four screws).
3. Connect the external cables according to the wiring
diagram.
Detectors can be addressed by using a special hand-held programming unit or they can be
automatically addressed from the control panel after installation completion; note that the
automatic addressing feature must be implemented by the control panel manufacturer: check the
panel’s literature to determine whether this operation can be performed.
Addresses may be selected through a 1 to 240 range and each device on the loop must have a unique
address.

SETTING THE ADDRESS - ONLY FOR VEGA INTELLIGENT DETECTORS
Air flow direction
The DDH shall be installed pointing towards the air flow direction
DDH dimensions in mm
71) Position the detector centrally on the DDH adaptor base
ensuring it is level.
INSTALLING THE DETECTOR
2) Rotate clockwise applying gentle pressure. The detector will
drop into its keyed location.
3) Continue to rotate clockwise a few degrees until the detector
has fully engaged in the adaptor base.
4) When the detector is firmly engaged,
check the alignment of the raised
reference marks on the detector and
on the base.

DETECTOR TESTING
Check the detector with an approved smoke detector tester.
1) Move the "test hole plug" to the side and
briefly release a spray of aerosol.
2) When alarmed, the LED lit on the
red light and the panel goes into
alarm condition.
IMPORTANT!
Reinstall accurately the "test hole plug".
Do not drill any holes in the cover for any reason.
Holes will cause air leakages and seriously
interfere with the response of the detector.
Drill a hole Ø 38 mm.
FITTING OF THE VENTURI PIPES IN DUCTS HAVING DIFFERENT DIAMETERS
Drill a hole Ø 38 mm.
Max diameter of the duct 0.6 m.
Use the Venturi pipe 0.6 m.
Shorten the pipe, if necessary.
For ducts with a ø less than 0.6 m use the 0.6 m pipe.
For ducts with a ø between 0.6 m and 1.4 m use the 1.5 m pipe.
For ducts which are larger than 1.4 m use the 2.8 m pipe.
NOTE!
Drill a hole Ø 51 mm.
Diameter of the duct
bigger than 0.6 m.
The Venturi pipe should
penetrate the whole duct.
Shorten the pipe to correct length.
Insert the end plug.
Put on the plastic end gasket.
Put on the rubber gasket.
The Venturi pipe shall not protrude more
than 30 mm max through the duct wall.

BRACKET FOR CIRCULAR OR INSULATED RECTANGULAR DUCTS
If using the bracket, the diameter of the duct
can be as small as 100 mm. The bracket is
supplied with a rubber gasket and a sealing sleeve.

- Check that the DDH is correctly installed pointing towards the air flow
in the duct.
- Ensure all glands are fully sealed and no openings remain to allow air
leakage which may prevent effective operation.
- Check that the plastic plug of the test hole is properly and accurately
installed.
- It is recommended that smoke from a smoke generator is introduced
into the duct to check the detector’s function.
FINAL CHECKS
WARNINGS AND LIMITATIONS
Our devices use high quality electronic components and plastic materials that are highly resistant to environmental deterioration. However, after 10
years of continuous operation, it is advisable to replace the devices in order to minimize the risk of reduced performance caused by external fac-
tors. Ensure that this device is only used with compatible control panels. Detection systems must be checked, serviced and maintained on a regular
basis to confirm correct operation.
Smoke detectors may respond differently to various kinds of smoke particles, thus application advice should be sought for special risks. Detectors
cannot respond correctly if barriers exist between them and the fire location and may be affected by special environmental conditions.
Refer to and follow national codes of practice and other internationally recognized fire engineering standards.
Appropriate risk assessment should be carried out initially to determine correct design criteria and updated periodically.
