2. Features

The LDM150R Remote Sensor is a range of gas detectors to be used with monitoring units LDM150R.

3. Models

Model
743-203-HFC / 743-203-HFCHV
743-203-NH3 / 743-203-NH3HV
743-203-CO2 / 743-203-CO2HV

4. Function

The sensor continuously measures the gas concentration and gives an analog signal to the monitoring
unit, when the signal reaches the alarm thresholds an alarm will be activated.
Alarm levels are always set in the monitoring unit.

5. Installation/Positioning

The general rule is that the detector should be placed as close to the potential leak as possible, and at
the same time consider the gas density and any air movements in the room. The detector must also
be positioned in such a way that it is easily accessible for service. See Fig. 1 for suggestions on
suitable placement. Installation is carried out according to the Fig. 4.

6. Function Control

Testing the system is recommended to be done once a year.
