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 alarms due to contamination
- 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
different positions: 0°, 90°, 180° 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.
