Calectro UG-7-A6O in BULGARIA

CHARACTERISTICS
- High efficient single sampling tube
- Easy to install
- Automatic sensitivity adjustment
FUNCTION
Smoke entering the duct system will be dispersed throughout
the whole building. The Uniguard duct detectors utilizes the
photoelectric sensing method and is designed to sense the
existence of smoke in the duct. This design of the housing
along with the detector technology is capable of detecting
unsafe conditions by sampling the air through the duct. When
the smoke is detected, it will emit a signal that will create the
urgency for proper action to be taken to turn off circulating fans,
blowers and any other auxiliary devices that are connected to
the system. The actions taken will enable the management
of hazardous smoke through the entire space that is being
protected by the duct detection arrangement.
This Uniguard comes in two models: UG-7-A6O-24V is
operating with 24V DC/AC and UG-7-A6O-120V with 120V
AC. Alarm and supervisory relay contacts are accessible
to interface with a control panel, HVAC control, and multiple
auxiliary functions including turning off the fan.
The Uniguard can be installed on any side of the duct.
The detector UG-7-A6O contains an intelligent controlling
circuit. This circuit is adjusting the sensitivity to give an
optimal function during the whole life time of the detector.
When the controlling circuit can no longer compensate for
contamination, a service alarm is indicated.
UG-7-A6O has a linking function that allows interconnection
between maximum 100 units. The linking function can close
dampers or stop fans further away in the ventilation system,
before the smoke has reached the places were the linked
detectors are installed. When one of the linked UG-7-A6O
goes into smoke alarm, all other detectors AUX relays are
activated.
