1.2.3 Alarm (threshold 3)
This state occurs when the gas concentration exceeds the alarm threshold (3rd threshold).
Actions to be taken:
remove bystanders from the danger zone,
as far as possible, allow the airing of the endangered rooms – by opening windows and doors (if
the control unit does not automatically switch on the ventilation).
1.2.4 Failure
Simultaneously with the process of gas concentration measurement, the detector performs a number of
diagnostic measurements in order to validate its own work and the system operation.
The internal failures signalled by the detector concern problems with the sensor.
The system failures signalled by the detector may concern:
breakage of the bus,
abnormal values of currents flowing into the detector,
incorrect settings of the configuration switch,
1.2.5 Warm – up
After powering the detector, the parameters of the sensor stabilize for some time. In this state, the detector
does not conduct measurements. This state takes about 1 minute, after which the sensor starts to operate
normally.
2 Safety
Do not allow cutting or damaging the insulation of the wires connecting the system.
Do not install a gas detector in places exposed to direct sunlight and water.
In the case of damage, shut down the detector, secure the connection cables, and conduct
the service.
All activities related to connecting detectors, signallers and other system components must
be carried out while Control Unit's power supply is off.
