FUNCTION
Uniguard has been developed to detect smoke in ventilation
ducts and consists of a smoke detector, mounted in an adapter
system where both tube and housing are specially designed
for optimum airflow throughthesmoke detector.
The system fulfills all the requirements for good fire detection
with airflow speeds from 0.2 m/sto20m/s.
Aventuripipewithauxiliaryfanshouldbeusedtodetectsmoke
in situations where ventilation is turned off and there is limited
airflowin the duct.
UG-3-NS-AOS is used together with control unit KE-1000 to
control fire dampers and fans, activate acoustic and/or optical
alarms etc.
The detectoris equipped with a bayonetmount,whichmakes it
easytoreplace.
The detector’s address is set with a DIL-switch. The DIL-
switch allows 32 addresses to be set. When an alarm occurs,
the detector’s address is shown on a display. The detector
contains an intelligent monitoring circuit that adjusts the
sensitivity to give optimum functionality during the whole life of
the detector. When the detector can no longer compensate for
environmental influences, a service alarm is indicated.
Foralarm- and service alarmfunction, please see next page.
Uniguard Superflow has 4 pre-assembled Klikseal-type IP67-
approved cable entries with automatic load anchorage for
cablediameters 4 -11 mm.
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 normally flow meters etc. should be mounted, please
seeour installation instructions.
You can also use your national or local rules for mountage
according to ”Methods for measuring airflow in ventilation
systems”.

UG-3-NS-AOS UNIGUARD SUPERFLOW
Analogue and addressable smoke detector for duct installation.
Optical function.
INSTALLATION
The tube is made of aluminium and can easily be shortened
to suit the diameter of the duct. Hole diameter is 35 mm. With
insulated or circular ducts - use the mounting bracket, hole
diameter is then 51 mm.
MAINTAINANCE
When the detector becomes contaminated, and when the
detector no longer can compensate for it, the central panel
will indicate a service alarm. This can be avoided for a
considerable time by cleaning the detector once a year with
a vacuum cleaner.
CHECKING AIR FLOW
The detector is equipped with a flow indicator which oscillates
in the air stream when the detector is correctly installed. This
gives simple confirmation that there is no leakage, and that air
from the ventilation duct is flowing through the detector.
FUNCTION TEST
When 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 cover.
Do not forget to refit the plastic plug after test.
NOTE! When installing outdoors or in cold attics etc., where
there is a risk for condensation, this requires that the detector
is insulated from the surrounding air by means of for example
our waterproof housing UG-SH, and marked with an extra
indicator lamp, LED-03 and a sign marked ”Hidden Detector”.

Evaluation period
The analogue smoke detector controls the alarm signals from
smoke in it´s chamber by measuring time, amplitude of signal
and signal spread. Before transmitting a fire signal the smoke
valuemust conform with preset data.

Service alarm
Short duration, large signals from disturbances such as
transients or small insects will not influence the analogue
smoke detector.
Reliable operationisensured as thealarm limitoftheanalogue
smoke detector is self compensating, i.e. it will always remain
at the correct preset value due to the built-in intelligence
compensating for environmentalchanges.
Historical datastorage:
Each detector module maintains a historical database
including the detector module identification number, number of
alarmsandfaults andthedate whenthe detectorwasplacedin
