tRoubleshooting
For a New Installation, the typical problems encountered are related to the
installation or conguration 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 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, reconguring units, changing or adding video surveillance
components, changing any electrical wiring, roong changes, painting,
etc. Even with a small change, wiring can be disturbed or disconnected or
something new can interfere with equipment operation.
• If 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 VP is not working, start at step 1 and proceed until the
problem is found and corrected.
• If the VP 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 nd problems, prevent confusion, and save time if site service by a
technician is required.
Test power and communication
Step 1
Does the VP 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 by checking the display of the VP. 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 & 3.
Step 2
Is the voltage at the VP, connector P1 pins 1 & 3, 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
