FUNCTION
The Uniguard 8 has been developed to detect smoke in
ventilation ducts. The UG8 contains a smoke detector that
detects if the air in the ventilation duct contains smoke or
fire particles. The sampling tube uses the venturi principle
which, when mounted in the duct, creates an airflow that goes
through the Uniguard as air moves through the ventilation duct.
The Uniguard and the design of the sampling tube ensures
detection even at very low air velocities, down to 100 ft/min
(0.5 m/s).
The sampling tube and its rotation part is mounted separately
on the duct. This facilitates installations in very tight places
compared to other models on the market and previous Unigard
duct smoke detectors, with integrated mounting of sampling
tube.
The UG8 is only 76 mm high and can be turned in any direction
(360º) on the rotation part, which makes the installation and
connection of cables very convenient.
To make installations and services easy, the UG8 is equipped
with snap-on lids over both the detector chamber and the
connection terminals as well as push in terminals.
UG8 has built in relays for direct connection of safety functions
such as fire dampers. There are also relays that are activated
due to contamination and system failure. Reset of a smoke
alarm is done via the reset button or a short circuit between
RST and RST GND on the PCB.
Additional features of the UG8 which are beyond the UL
requirements are a Low Airflow Alarm and an Automatic
Sensitivity Adjustment. To activate the built in Low Airflow
alarm, remove the jumper. The Low Airflow alarm relay will
activate below approx. 250 ft/min (1.3 m/s) air velocity in the
ventilation duct. The Automatic Sensitivity Adjustment is
achived by a built in intelligent controlling circuit in the UG8.
This enables a longer lifespan of the detector and fewer false
alarms due to contamination.
