Chapter 4: Reports 
166  P/N 3102351-EN • REV 005 • ISS 28DEC18 
Device Maintenance report 
The panel provides a Device Maintenance report of all detectors in the system. The report can 
include: all detectors, all detectors over 20% dirty, or all detectors over 80% dirty. The report 
displays the device, along with its dirty percentage and sensitivity setting. Device Maintenance 
reports can be printed or viewed on the LCD. 
Note: On an unconfigured system with a full load of CO devices, after the system has been 
configured, it takes approximately 1.5 hours to retrieve the CO running days data from all 
devices. For subsequent restarts,without reprogramming, the delay in reporting the running 
days is less than 5 minutes. 
To view a Device Maintenance report: 
1.  Press the menu button and choose Reports. 
2.  Choose Device Maintenance. 
3.  Choose one of the following: 
All Devices 
Devices >= 20% Dirty 
Devices >= 80% Dirty. 
 
Notes 
•  CO detectors have a lifespan of six years. They report the number of months left until end 
of life (EOL) on the LCD and in maintenance reports. When a CO detector has less than six 
months until EOL, the LCD displays a maintenance alert. When the months until EOL reach 
zero, the LCD restores the maintenance alert and issues an EOL trouble for the device. For 
combination detectors, the system detects and reports the percent dirty separate from the 
CO number of months until EOL. 
•  COD, HCD, PCD, and PHCD detectors have a lifespan of ten years. They report the 
number of months left until end of life on the LCD and in maintenance reports. When a CO 
detector has less than six months until EOL, the LCD displays a maintenance alert. When 
the months until EOL reach zero, the LCD restores the maintenance alert and issues an 
EOL trouble for the device. For combination detectors, the system detects and reports the 
percent dirty separate from the CO number of months until EOL.
