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

UG-3-A4O UNIGUARD SUPERFLOW STAND-ALONE-UNIT 24V
Optical smoke detector with service alarm for duct installation.
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
for 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.
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.
