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.

Operation

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.

circular ducts)

outdoors, in cold attics etc.)
VR-0.6M Venturi pipe 0.6m
VR-1.5M Venturi pipel.5m
YR-2.8M Venturi pipe 2.8m
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 circular ducts - use the mounting bracket, hole diameter is then 51 mm.
MAINTAINANCE
When the detector becomes contaminated, sensitivity is increased, triggering the service alarm. This can be avoided fo r a considerable time by cleaning the detector once a year with a vacuum cleaner.
AIR FLOW MONITORING
The detector is fitted with a red plastic switch tongue. When the detector is correctly installed, the tongue is bent outwards by the air flow. The switch tongue provides a simple confirmation that there is no leakage and that the air flow from the duct is in fact flowing through the housing.
FUNCTION TEST
When installation is complete, the detector should be tested. This can be carried out with smoke or suitable aerosol
testspray.

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. In such cases it should be marked with a sign "Hidden Detector".

FUNCTION
Normal operation: In normal operation the alarm relay is energized, and the relay contacts
are closed between C and NC.
Smoke alarm: The LED of the detector is showing red light and the relay contacts are
changing to C and NO.
Reset: Press the reset button to reset the detector into normal operation.
Alarm 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.
Failure:: If there is something wrong with the detector, the alarm relay will change
contacts:
a) When the detector module is removed
b) When the supply voltage is interrupted
