UG-3-O
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 20 m/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.
Uniguard is used together with a control unit (e.g. ABAV-S3) 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.
UG-3-O has an intelligent monitoring circuit that continuously checks and adjusts the sensitivity for optimum functionality during the entire life of the detector. When the detector can no longer compensate for environmental influences a service alarm is generated, which indicates that the detector needs replacement or cleaning.
Uniguard Superflow has 4 pre-assembled Klikseal-type IP67-approved cable entries with automatic load anchorage for cable diameters 4 – 11 mm.
The venturi tube is made of aluminium and can easily be shortened to suit the diameter of the duct. Hole Ø is 38 mm. For insulated/circular ducts with mounting bracket, Ø is 51 mm. When installation is complete, the detector should be tested. The test can be carried out with test spray SOLO A5 (from Calectro), a short spray through the test hole in the cover. Refit the plastic plug after the test.
NB: When installing outdoors or in cold attics etc. the detector should be insulated from the surrounding air by with e.g. our weatherproof housing UG-COVER. In such cases it should also be marked with an extra indicator lamp, LED-03 and a sign marked HIDDEN DETECTOR.
