internal problem. Replace the Base Station. In rare cases a
problem with the MCU can cause this error.
2,3 No communication with one or more
Base Stations on this MCU. Check cabling to verify that the Base
Station's cable is plugged into and fully
seated in the Base Station port at the back of
the MCU and plugged into the Base Station
at the other end.
If the LED on the Base Station is not lit,
check for proper wiring of the 8-pin modular
plugs. See section 4.3.
If the cable is over 600 feet long, verify that
the extra wire pairs have been connected
correctly.
If the Base Station LED is flashing red, check
for open or shorts on pins 1 and 2 of the
cable.
If the Base Station has been removed,
acknowledge the alarm by moving the Mode
Switch to REGISTER. Press the STEP
button until the LED for the removed Base
Station is blinking. Press DEL/ENTER, then
move the Mode Switch back to NORMAL.
