Max voltage: 250 VAC
Switching differential: 30 Pa
Service life: > 1 000 000 cycles
Material: - Housing: ABS
- Housing cover: PC
- Membrane: Silicone
- Duct connectors: ABS
Weight: 150 gram
Product data: Max. pressure 50k Pa
Media: Air and non-aggressive gases
Temperature:: -20...+60°C (Operation),
-40...+80°C (Storage)

Air sampling pipe Aluminium
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. With insu-
lated or circular ducts - use the mounting bracket, hole diameter is
then 51 mm.
MAINTENANCE
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.
DIMENSIONS (MM)
FUNCTION TEST
When installation is complete, the detector should be tested. This
can be carried out with smoke or suitable testspray using the test
hole on cover.
Do not forget to refit the plastic plug after test.
VENTURI EFFECT
The slots alongside the venturi pipe, for the inlet and the outlet
of the venturi air stream, gives maximum air flow and make
the venturi pipe self-adjusting with a stable and uniform flow from the
whole cross section of the ventilation duct
WIRING DIAGRAM
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-COVER and marked with
an extra indicator lamp, LED-03 and a sign marked
”Hidden Detector”.
