FUNCTION
The UG8 Uniguard has been developed to measure smoke
in ventilation ducts and consists of a smoke detector and
duct enclosure system, specially-designed for optimal airflow
through the smoke detector.
The UG8 can be mounted on either side of the duct. The UG8
comes a rotating section that, together with your chosen Venturi
tube, is mounted on the ventilation duct. It also has a "FLOW
arrow" for easy installation in the correct direction for the
airflow. The direction of the arrow should correspond with the
direction of the airflow in the duct. The patent-pending detector
enclosure with cable inputs and reset button can be rotated in
any direction to suit the characteristics of the mounting location.
Both the smoke detector chamber and connection chamber
covers have snap locks for quick access.
Relays:
• Two alarm relays to, for example, control fire protection
dampers or to start/stop the ventilation fans.
• A service alarm relay and low-flow alarm relay, which
indicate when maintenance is needed before a false alarm
occurs, as well as that the airflow in the duct is low or that the
UG8 is mounted at an unsuitable place in the duct.
• A system failure relay, which indicates failures in the smoke
detector circuit.
The detector has an intelligent monitoring circuit that constantly
checks and adjusts the sensitivity for optimum functionality
throughout its service life. When the detector can no longer
compensate for contamination and starts to approach a false
alarm, a service alarm will be indicated.
The detector is fitted with a bayonet mount, making it easy to
fit and remove. If a system failure occurs in the UG8, e.g. if a
detector is removed, a yellow LED on the circuit board will start
to flash and the system failure relay will be disabled. In the even
of a system failure, other relays will also be disabled. The UG8
can be used with Calectro's ST280 and ST580 Venturi tubes,
as well as the extension tube ST-EXTEND.
