FEATURES
The DG-LINK line is a range of gas detectors for use with the
monitoring unit GAS CENTER.
FUNCTION
The sensor continuously measures the concentration of gas
and outputs an analog signal at the GAS CENTER, when the
signal reaches the alarm thresholds an alarm will be activated.
Alarm levels are always set in the monitoring unit.
INSTALLATION
Connect the detector according to the wiring diagram.
FUNCTION CONTROL
Testing the system is recommended to be done twice a year.

DG-CO2-IP67-LINK has an internal heating element to
keep the optics free of fog. Therefore the detector requires
separate power supplies for the detector and the built-in heating
element.
Make sure cables and power supply have sufficient capacity!

MOUNTING
The plastic tube with the sensor head shall be mounted through
the duct wall. The tube gland holds the plastic tube and seals
against the duct. Check locations of the holes in the plastic
tube, it is important that they are mounted correctly to get a
good airflow through the tube.
A distance of three times the duct diameter should be left
before a damper, filter or change of the duct direction, and 5
times the diameter after these devices.
PLEASE NOTE
The sensor has limited selectivity for different types
of gas. If the detector is placed in the environment
in which other gases or fumes may be present,
these compounds might generate false alarms.
Examples of substances that can cause false
alarms are petrol fumes, solvents, cleaning agents,
cigarette smoke, etc.
Specifications subject to change.
