1.2.4
Failure
In parallel to measurements of gas concentration the detector carries out a series of self-test measurements
to verify fault-free operation of the sensor and the gas monitoring system as a whole.
The defects indicated by the gas detectors may include:
problems with built-in gas sensors,
error of communication with the control unit,
incorrect configuration,
interrupted /broken connection with the Teta MiniDet detector.
1.2.5
Warm – up
After power on the detector need some time to stabilize operation parameters of sensors. It is the time
period when no measurements are taken. Such a warm-up procedure takes about two minutes and the
detector starts normal operation.

Safety
Do never install gas detectors at locations exposed to direct effect of water (moisture) or
direct sunlight.
When defects are revealed switch the detector off, secure connection cables and contact
maintenance staff or a service team.
All activities related to connecting detectors must be carried out while Control Unit's power
supply is off.
Despite the power supply voltage for the Gas Safety System is off, dangerous voltage may
persist across terminals of the Control Unit. Such a voltage may come from another system
controlled by the same unit, for instance ventilation, that use one output pin of the Control
Unit.
The gas detector must be reliably secured during any repair, installation or maintenance
works.
