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 through the smoke detector.
The system fulfills all the requirements for good fire detection
with airflow speeds from 0.2 m/s to 20m/s.
A venturi pipe with auxiliary fan should be used to detect smoke
in situations where ventilation is turned off and there is limited
airflow in 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 detector is equipped with a bayonet mount, which makes it
easy to replace.
The detector’s address is set with a DIL-switch. The DILswitch
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.
For alarm- and service alarm function, please see next page.
Uniguard Superflow has 4 pre-assembled Klikseal-type IP67-
approved cable entries with automatic load anchorage for
cable diameters 4 - 11 mm.
