Factory default settings
On being started up for the first time, the system operates with the basic factory settings:
– The emergency power supply connection and the alkaline batteries of the central unit are not monitored.
– Mean values are calculated over a period of 30 minutes (for NO
– Alarm threshold settings for the different transmitters:
Actual value Alarm A1
threshold
hysteresis
Actual value Alarm A2
threshold
hysteresis
Actual value Alarm A3

Actual value Alarm A4

Mean value Alarm A1

Mean value Alarm A2

Mean value Alarm A3

Mean value Alarm A4

The transmitter values for other gases are listed in the data sheet of the transmitter concerned.
Hysteresis of e.g. 10 ppm with a limit of e.g. 100 ppm means that the alarm is set at 100 ppm and reset if the
value falls below 90 ppm.
These default settings can only be altered by DrägerService.
