TROUBLESHOOTING
For a
New Installation,
the typical problems encountered are related to the
installation or con
fi
guration process. Start at step 1 in the Troubleshooting
Steps section and proceed until the problem is found and resolved.
For an
Existing (previously working) Installation,
the
fi
rst step is to determine
whether anything has been changed at the site. For instance, Has there
been any new construction? This includes any changes to the site,
adding units, recon
fi
guring units, changing or adding video surveillance
components, changing any electrical wiring, roo
fi
ng changes, painting,
etc. Even with a small change, wiring can be disturbed or disconnected or
something new can interfere with equipment operation.
I
•
f there has been new construction, start at step 1 in the
Troubleshooting Steps section and proceed until the problem is
found and resolved.
If the APEX is not working, start at step 1 and proceed until the
•
problem is found and corrected.
If the APEX is receiving power, start at step 4 and proceed until the
•
problem is found and corrected.
Keep thorough notes during troubleshooting to compare against and to
help
fi
nd problems, prevent confusion, and save time if site service by a
technician is required.
Test power and communication
Step 1
Does the APEX Access Device have Power?
Yes – Proceed to step 2
No – Check Power Supply and Wiring and retest or see Multiple
Device Problems
This can be tested quickly by checking the display of the APEX. If the
display is on or if any of the LEDs on the board are on, the board has
power. If there is no indication of power from the display or LEDs, use a
volt meter to check for the presence of voltage on connector P1 pins 1 &
2.
Step 2
Is the voltage at the APEX, connector P1 pins 1 & 2, greater than 10.5
Volts? (Use a volt meter to measure the voltage).
Yes – Proceed to step 3
No – Check Power Supply and Wiring and retest
