Self-Diagnosis Of Internal Devices; Address Setting Check; Polling Led - Panasonic Firetracker FT1020G3 CIE Technical And Programming Manual

1. During 13 minutes, all the momentary smoke obscuration values are saved and an
average value is calculated. The CCF will be changed directly if the average value
is lower than the actual CCF, else no change.
2. This is valid for 18 hours. Then the CCF will be changed also if the average value
is higher than the actual CCF. (It will normally be higher because of contamination.)
3. After another 18 hours (i.e. in total 36 hours) the CCF will be changed if the average
value is lower or higher than the actual CCF and it will be saved in the detector's
EEPROM, i.e. it can be used e.g. after the detector has been without power supply.
4. A new 18 + 18 = 36 hours period starts with an average value calculation every 13
minute.
Maximum Contamination Compensation Factor (CCF) is 2 %/m. Service signal will then
be activated and shown in the CIE.
The following is valid for the different type of detectors:

4452: This detector has sensitivity compensation. No Service signal.

4400: This detector has sensitivity compensation. Service signal.

4401: This detector has sensitivity compensation. Service signal.

Self-diagnosis of internal devices

The detectors perform an internal check of some vital functions and components (e.g. the
IR-LED). In some modes a separate fault message will be shown in the CIE
The following is valid for the different type of detectors:

4452: This detector has no self-diagnosis of internal devices.

4400: This detector has self-diagnosis of internal devices. A fault message will be
shown in the CIE.

4401: This detector has self-diagnosis of internal devices. A fault message will be
shown in the CIE .

Address setting check

The red indication LEDs in the detectors 4401 and 4400 will in all modes be blinking every
second when the detector is powered and the COM loop address is not set with the
Address setting tool 3314 / 4414, i.e. as long as the address is "000". The address should
be set in the interval 001-255.
Note: 4414 is required when Advanced mode shall be used.

Polling LED

The green polling LED in the detectors 4401 and 4400 can in Advanced mode be
set (via EBLWin) to be blinking (20 ms / 7 s), indicating that it receives the commands from
the CIE correctly.
Note: When the detector is in test mode the green polling LED will be turned off, indicating
it is in test mode.
