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.
