Heavy pollution: Exchange detector immediately
O fault: optical sensor is deactivated.
Temperature in Celsius
The Carbon monoxide (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.
Thermal sensor fault
The operation time of the C sensor exceeds the maximum time
of operation.
