UG-3-A4O UNIGUARD SUPERFLOW STAND-ALONE-UNIT 24V

Optical smoke detector with service alarm for duct installation.

CHARACTERISTICS

-  Patented venturi pipe and duct housing

-  One-pipe air sampling system Uniguard Superflow

-  New cross-section (shape) of the venturi pipe 

gives an optimum of venturi effect

-  Service alarm

-  Test hole on cover

-  Simple installation

-  Sensitive flow indicator

-  Simple service and maintenance

-  Installer-friendly connection of cables

-  Foolproof installation of venturi pipe

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.

There is a built-in 

alarm relay

 to control fire-safety dampers, 

to stop ventilation fans, or to activate accoustic and optical 
alarms etc.

There is a built-in 

service alarm

 relay to let you know when 

maintenance is needed, before a false alarm occurs.

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 can no longer compensate for contamination, a service 
alarm is indicated.

Uniguard Superflow has 4 premounted IP67 approved cable 
entries with built-in cable anchorage for diameter 4-11 mm, 
type Klikseal.

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 pipe to correct length. 

Insert the end plug. 

Put on the end plastic 
gasket. 

Put on the rubber 
gasket, TET 26-35. 

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 pipe 0,6 m.
Shorten the pipe, 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 pipe shall not 
protrude more than 30 mm 
through the duct wall. 

Diameter of the duct bigger
than 0,6 m.
The venturi pipe should 
penetrate the whole duct.
