Page 8: Principle Of Operation
Principle of operation OptoRex DO1101-Ex ThermoRex DT1101-Ex / DT1102-Ex The OptoRex DO1101-Ex is based on the principle that The ThermoRex DT1101/DT1102 measures the ambient smoke scatters light. An infrared LED (IRED) transmits temperature with the NTC thermistor R in the tip of the brief, intensive light pulses into the scattering chamber. -

Page 11: Commissioning
Commissioning To prevent unnecessary soiling during the construction phase, the detectors should be inserted into the bases just before the system is put into service. For detailed information, see «Fire Detection in Explosion-hazard Areas», document e1204. . Maintenance Functional check A functional check of the detectors must be performed periodically (usually once per year) by forcing each detector to respond by means of a suitable testing device (RE6 or DZ1192 for DO1101-Ex... -
