Duct Smoke DETECTOR Uniguard UG-3-A50
Optical duct smoke DETECTOR with automatic sensitivity adjustment, service alarm, and built-in control unit, 230V | UG-3-A50
Description UG-3-A50
The Uniguard is designed to detect smoke in ventilation ducts. It consists of a smoke DETECTOR with relay outputs mounted in an adapter system. The pipe as well as the housing are specially designed for optimal airflow through the smoke DETECTOR.
The system meets all requirements for effective fire detection with airflow speeds from 0.2 m/s to 20 m/s.
A venturi pipe with auxiliary fan can be used to detect smoke in situations where ventilation is switched off, resulting in limited airflow in the duct.
Uniguard has a built-in control unit to operate fire dampers and fans, or to activate acoustic and/or optical alarms, etc.
Since the duct smoke DETECTOR is equipped with a bayonet lock, it can be easily replaced.
UG-3-A50 has an intelligent monitoring circuit that continuously checks and adjusts sensitivity for optimal functionality throughout the entire lifespan of the DETECTOR. When the duct smoke DETECTOR can no longer compensate for environmental influences, a service alarm is triggered. This indicates that it is time to replace or clean the DETECTOR.
Uniguard Superflow has 4 pre-assembled Klikseal-type IP67 approved cable entries with automatic strain relief for cable diameters 4 – 11 mm.
Installation
The venturi pipe is made of aluminum and can be easily shortened. It can then be fitted to the diameter of the duct. Hole Ø is 38 mm. For insulated/round ducts with mounting bracket, Ø 51 mm.
Once installation is complete, it is necessary to test the duct smoke DETECTOR. The test can be performed with test spray SOLO A5 (from Calectro). A short spray through the test hole in the cover should be sufficient. Replace the plastic plug after the test.
NB: If installation takes place outdoors or in cold attics, etc., the DETECTOR must be insulated from ambient air. For example, with our weatherproof housing UG-COVER. In such cases, it is advisable to mark this with a sign “HIDDEN DETECTOR”.
