LED on smoke detector: Green - service alarm
(contamination)
Red - smoke alarm
LED on PCB: Green - normal operation
Yellow - system error
Yellow - Low-Flow
Adaptor housing: ABS
Protection class:
IP54
Air sampling tube: Aluminium.
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
4 lengths; 0,3 m, 0,6 m, 1,5 m 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.
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.

Drill a hole
Ø 38 mm.
Diameter of the duct bigger
than 0,6 m.
The venturi tube should
penetrate the whole duct.
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.
The venturi tube shall not
protrude more than 30 mm
through the duct wall.

- 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.
Any receiving device of relay status should consider alarm
indications up to 10 milliseconds as normal no-alarm condition.
Receiving devices can be: Actuator for fire/smoke dampers,
fire alarm panels, smoke evacuation fans etc.
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.
