Smoke Detector UG8-E-24/230 Optical for Duct Mounting, Calectro

Uniguard UG8 is developed to measure flue gases in ventilation ducts and consists of a smoke detector and a duct enclosure system specially adapted for optimal airflow through the smoke detector.

UG8 can be mounted on either side of the duct. UG8 is delivered with a rotation detail that, together with the chosen venturi tube, is mounted on the ventilation duct. It also has a "FLOW arrow" for easy installation in the correct airflow direction. The direction of the arrow should match the airflow direction in the duct. The patent-pending detector enclosure with cable entries and reset button can be rotated in any direction to adapt to the characteristics of the installation site.
Both the cover for the smoke detector chamber and the connection chamber have snap locks for tool-free and quick handling.

Relays:
• Two alarm relays for, for example, controlling fire dampers or starting/stopping ventilation fans.
• A service alarm and low flow alarm relay that indicates when maintenance is needed before a false alarm occurs and indicates that the airflow in the duct is low or that UG8 is mounted in an unsuitable location on the duct.
• A system fault relay that indicates faults in the smoke detector circuit.

The detector has an intelligent monitoring circuit that continuously checks and adjusts the sensitivity for optimal function throughout the detector's lifespan. When the detector can no longer compensate for contamination and is approaching a false alarm, a service alarm is indicated.

The detector is equipped with a bayonet fitting, making it easy to install and remove. If a system fault in UG8 occurs, such as a removed detector, the yellow LED on the circuit board starts blinking, and the system fault relay is deactivated. Other relays are also deactivated in the event of a system fault.

UG8 can be used with Calectro's ST280 and ST580 as well as the extension tube ST-EXTEND.
