7� Maintenance and Troubleshooting
Although very little maintenance is required with Alpha systems, routine checks and adjustments are recommended
to ensure optimum system performance. Only qualified service personnel should do the repairs.
Use extreme care when working inside the unit while the system is energized. Do not
make contact with live components or parts.
Circuit cards, including RAM chips, can be damaged by static electricity. Always wear a
grounded wrist strap when handling or installing circuit cards.
Ensure redundant modules or batteries are used to eliminate the threat of service inter-
ruptions while performing maintenance on the system’s alarms and control settings.
The following table lists a few maintenance procedures for this system. These procedures should be performed at
least once a year.

7�1 Fan Tray Replacement
The fan tray must be replaced by a qualified technician. The maintenance interval for a fan tray is 5 years at 30°C. It
is replaced as a single unit. Individual fans are not replaceable. The procedure will take approximately five minutes
and the system performs uninterrupted during this process.
1. Unplug power cable and remove signal wiring, if applicable (shown in #1).
2. Loosen the two front panel screws (shown in #2) and slide assembly forward to remove.
3. Replace with new assembly.
4. Plug power cable back in and then attach signal wiring if applicable.
