The DOTE1152 is provided with a line isolation function. As a distinctive feature, the DOTE1152 detector is marked with a yellow circle which is visible when the detector is installed. Fire & Security Products e4070e Siemens Building Technologies Group 10.2002...
Halogen-free plastic material identifiable through embossed code Note: The specified ambient conditions in accordance with the technical data must be met, to avoid a reduction of the service life of the CO sensor. e4070e Fire & Security Products Siemens Building Technologies Group 10.2002...
CO is present. (Priority CO.) Furthermore, it is possible to use the parameter sets of the DOT1151/52 without CO signal evaluation (see Technical specification, document no. 1027). Fire & Security Products e4070e Siemens Building Technologies Group 10.2002...

The driver for the response indicators (RI) activates the internal RI and an ex- ternal RI under control of the control unit. Fire & Security Products e4070e Siemens Building Technologies Group 10.2002...
If the DOTE1152 can no longer be periodically addressed, for example due to a µP failure in the control unit, the detector automatically switches to emergency opera- tion. In the event of a fire the detector can still trigger a collective alarm. Fire & Security Products e4070e Siemens Building Technologies Group 10.2002...
Temperature and relative humidity values outside the specified range reduce the service life of the CO sensor. If the detector is exposed to an atmosphere containing solvents for longer periods, the CO sensor may be damaged. Fire & Security Products e4070e Siemens Building Technologies Group 10.2002...
The DOTE1152 must be exclusively used as a fire detector. No CO gas warning is possible, as the detector always evaluates the measured CO values together with other values measured and analyses them only for the early detection of fires. Fire & Security Products e4070e Siemens Building Technologies Group 10.2002...
Each base identification module is factory programmed with its own, unique serial number. If the swapped detectors are of a different type, an error message is signalled. Fire & Security Products e4070e Siemens Building Technologies Group 10.2002...
CO is reached, the internal and external response indicators flash at inter- vals of approx. 4 seconds. No danger level is signalled. If mechanically damaged detectors must be scrapped, the plastic materials can be sorted out based on the embossed code. Fire & Security Products e4070e Siemens Building Technologies Group 10.2002...
