O fault: optical sensor is deactivated.
Temperature in Celsius
Carbon monoxide (CO) analog value
The CO analog value specifies the currently measured CO concentration. The CO analog
value is between 0 for a normal operating condition and the maximum value 600.
Operation time
Operation time of the detector in hours starting from the initial start-up of the detector.
Detector state information
OK
General C malfunction. Possible causes:
–
–
The T sensor and the C sensor is off. The optical sensor is still in
operation.
Exchange the detector immediately.
The impedance of the electrochemical cell is too high.
The C sensor is off. The rest of the sensors are in operation.
Exchange the detector immediately.
The operating temperature exceeds the maximum value. The C
sensor is off. The rest of the sensors are still in operation.
Malfunction due to read/write error in the EEPROM. The detector is
off.
Exchange the detector immediately.
Number of read/write errors in the EEPROM.
Pollution level IR LED
The optical initial set-up value for infrared wavelengths of a new detector is stored in the
integrated EEPROM during the final inspection. The pollution level specifies by how much
this analog value has increased in comparison with the delivery state.
Pollution level blue LED
The optical initial set-up value for blue light wavelengths of a new detector is stored in
the integrated EEPROM during the final inspection. The pollution level specifies by how
much this analog value has increased in comparison with the delivery state.
ID
The 10-digit unique number to identify the detector through diagnostic screen or Remote
Services when connected to the panel.
EMC value
The EMC value indicates the EMC level.
Thermal sensor fault
The operation time of the C sensor exceeds the maximum time
of operation.
