nection „Connect HC-sensor “.
After the correct connection in place of the
flashing bar the serial number of the HC-
probe is indicated to the HC-probe.
During the warm-up phase (set to zero) the
COSA 707 counts down from 30 to 0.
With a HC-content over adjusted the alarm
threshold in the environment the indicator
value is represented in red, among them in
black. During a HC-detection over 40 ppm
(in the example) in the environment addi-
tionally an audio signal sounds to the red
announcement.
