Information on access to options – section 5.2 and 5.3.
For detailed description of the following options see detector User’s Manual.
Option
Description
1. History
This option allows the user to browse recorded statuses (threshold exceeding, faults) that
occurred at individual detectors. Status memory can be cleared.
2. Detector info
It displays detailed detector information, including:
• Range, alarm threshold values.
• Detector type and type name.
• Measured substance CAS No. and name.
• Detector’s time of operation in days, date of last calibration.
• Detector network address, its serial number.
• Information on detector diagnostic status (critical and non-critical fault records). When
fault codes are different than zero the icon
appears. Push bottom under the icon allows
to read information about fault type.
3.Concentration
graph
Presents the gas concentration graph recorded by individual detectors over the last 90
minutes of system operation.
4. Cancel lock
It allows users to cancel detector lock. This operation is possible when the detector is in lock
mode.
Prior to using this option, find out the requirements to be met and the
procedure for lock cancellation.
5. Zero detector
It makes it possible to zero the detector. After choosing this option, the Control Unit sends
a zero command to the detector.
Prior to using this option, find out the requirements to be met and the
procedure for detector zeroing.
6. Noise gateway
It makes it possible to set a detector noise gateway threshold parameter. Possible settings
range from 0 to 5%.
7. Alarm thresholds It makes it possible to set detector threshold levels. The user is requested to enter 6 values
– 3 alarm thresholds “upwards” and 3 “downwards”.
These possible settings include:
• not less than 10% of the range
• not more than 95% of the range
• for detectors operating with % LEL unit not more than 60% LEL
• it is possible to disable lower limits.
8.„Inhibit” mode
It is possible to exclude the detector. After activating this function, the detector is
disconnected from the system.
The “Inhibit” mode does not mean that the detector is without power supply.
It is not allowed to open it without prior power supply disconnection

Threshold settings are introduced in a physical unit, while limits are values entered in % of the range. Numeral values can vary.
