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 dete c tor.
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
value must 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 operation is ensured as the alarm limit of the analogue
smoke detector is self compensating, i.e. it will always remain
at the correct preset value due to the built-in intelligence
compensating for environmental changes.
Historical data storage:
Each detector module maintains a historical database
including the detector module identification number, number of
alarms and faults and the date when the detector was placed in
operation.
