UG-5-AFR-24V UNIGUARD SUPERFLOW STAND-ALONE-UNIT
Optical smoke detector with service alarm, for duct installation.
Electronic air-flow indication.
CHARACTERISTICS
- Automatic sensitivity adjustment enables longer
lifespan and fewer false alar ms due to cont amination
- Patented venturi pipe
- One-pipe air sampling system Uniguard Superflow
- Service alarm
- Test hole on cover
- Simple installation
- Electronic air-flow indicator
FUNCTION
Uniguard has been developed to detect smoke in ventilation
ducts and combines a smoke detector and an adaptor system
where both tube and housing are specially designed for
optimum airflow through the smoke detector.
The UG-5 can be installed on any side of the duct in four
dif ferent positions: 0°, 9 0°, 18 0° and 270°. Patented.
Relays:
• Two alarm relays to control fire-safety dampers, to stop
ventilation fans or to activate acoustic and optical alarms etc.
• One service alarm relay to let you know when maintenance
is needed, before a false alarm occurs.
• One system error relay indicating fault on the smoke
detector circuit.
• One Low-Flow relay indicating that air flow in the duct is low
or that the UG-5 is installed in an inexpedient place on the
duct.
The detector contains an intelligent controlling circuit. This
circuit is adjusting the sensitivity to give an optimal function
during the whole life time of the detector. When the controlling
circuit has reached the maximum sensitivity compensation for
contamination, a service alarm is indicated.
The detector has a bayonet fitting to simplify mounting and
removal.

Standard length 0,6 m. Hole diameter 38 mm.
The length of the venturi pipe shall be chosen based upon how
wide the ventilation duct is. The venturi pipes are available in 3
lengths; 0,6, 1,5 and 2,8 m. When the ventilation duct is wider
than 0,6 m (dia), the venturi pipe should penetrate the whole
duct. Please see below sketch.
Shorten the tube to correct length.
Insert the end plug.
Put on the end plastic
gasket.
Put on the rubber
gasket, HFU204.
NOTE!
Drill a hole
Ø 51 mm.
Drill a hole
Ø 38 mm.
Drill a hole
Ø 38 mm.
Max diameter of the duct 0,6 m.
Use the venturi tube 0,3 or 0,6 m.
Shorten the tube, if necessary.
For ducts with a ø of less than 0,6 m use the 0,6 m pipe.
For ducts with a ø of 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.
The venturi tube shall not
protrude more than 30 mm
through the duct wall.
Diameter of the duct bigger
than 0,6 m.
The venturi tube should
penetrate the whole duct.

Failure: If an error on the internal smoke
detector circuit occurs or when the
smoke detector is removed, the yellow
system error LED is lit and smoke
alarm, service alarm and system error
alarm relays are de-energized.
Low air flow: The yellow Low-Flow LED is lit (and
the relay is de-energized), when the air
speed in the duct is low or if the UG-5
is installed in an inexpedient position
on the duct or if the UG-5 is very dirty.
To make sure that the smoke detection
function is working, apply smoke (i.e.
from a smoke machine) into the duct
to check that the UG-5 is indicating a
smoke alarm.

BASIC PRINCIPLES FOR POSITIONING
For the airflow through the adaptor to be representative of the
airflow in the ventilation duct, install the detector at a place
where flow meters etc. normally are mounted, please see our
installation instructions.
You can also use your national or local rules for mountage
according to "Methods for measuring airflow in ventilation
systems".
INSTALLATION
The venturi pipe is made of aluminium and can easily be
shortened to suit the diameter of the duct. Hole diameter is
38 mm. For insulated or small circular ducts (100-150 mm) -
use the mounting bracket, hole diameter is then 51 mm.
MAINTENANCE
The detector contains an intelligent controlling circuit. This
circuit is adjusting the sensitivity to give an optimal function
during the whole life time of the detector. When the controlling
circuit has reached the maximum sensitivity compensation
for contamination, a service alarm is indicated. This can be
postponed for a considerable time by cleaning the detector
once a year with a vacuum cleaner.
AIR FLOW MONITORING
The detector has an electronic air flow monitoring. When the
detector is correctly installed, the yellow “Low-Flow” LED
is turned out. The function provides a simple confirmation
that the air flow from the duct is in fact flowing through the
housing. It is possible to disable the air flow monitoring in case
of special installations.
FUNCTION TEST
When the installation is complete, the detector should
be tested. This can be carried out with smoke or suitable
testspray, for example RDP-300 (from Calectro). Use the test
hole on the cover. Do not forg et to ref i t the plastic plu g af ter
test.
NB: When installing outdoors or in cold attics etc, where there
is a risk for condensation, the detector should be insulated
from the surrounding air with e.g. our weatherproof housing
UG-COVER-75. In such cases it should be marked with a sign
"Hidden Detector".
FUNCTION
Normal operation: In normal operation all relays are
energized.
Smoke alarm: The LED of the detector is showing
red light.
Reset: Press the reset button to reset the
detector into normal operation.
Service alarm: When the detector is sensing smoke or
is dirty the LED of the detector will first
show green colour before going into
alarm with red light. If the detector is
dirty, it will show green light. This is
an optical indication (a pre-alarm or
service-alarm) which means that the
detector is contaminated and if it is not
cleaned, it will give a false alarm later on.
