Overview: Missing points are points that are turned on in programming via the Point Index assigned to anything other than 0 and cannot be found by the panel on the Zonex Loop. This problem may have a number of causes such as; the point is actually not in the field, is wired incorrectly, has a faulty addressing device such as its POPIT or Octopopit, or there may be noise in the data loop.
When Points go missing, the panel generates responses based on the point type. Fire points generate Missing Trouble responses, non-fire 24 hour points will generate Missing Alarm responses. Points that are neither Fire nor 24 hour points will generate Missing Alarms when armed and Trouble when disarmed.
Issue
Panel history shows Missing Alarm. What does it mean?
Solution
This problem may have a number of causes such as; the point is actually not in the field, is wired incorrectly, has a faulty addressing device such as its POPIT or Octopopit, or there may be noise on the zonex data loop in the field.
New Installs - Only a few missing , verify the popits are addressed and wired to the correct zonex loop. (9000 Series Panels Zonex 1 is Addresses 9 to 127 and Zonex 2 is 129 to 247). If all on the same wire run verify the wiring from the last working popit to the first missing popit.
Exsisting Install that all was working - All popits missing - Remove all wire from the Zonex terminals for the missing popits (9000 Series Panels Zonex 1 is Addresses 9 to 127 and Zonex 2 is 129 to 247). Only wire the D8125 to the correct Zonex (Out of the panel to In of the D8125 and In of the panel to Out of the D8125). This would remove any D8128 Octopopit Modules and D8129 Relay Modules from the Zonex. Next, remove all loop wiring from the + /- Terminals of the D8125. Using View Point Status fro the Keypad or RPS verify the State of all the popits on the loop by add ing 1 loop at a time until you connect the loop or loops that are causing all to go missing. Once you have the bad loop or loops isolated - Divide and conquor the loop. Go out halpf way and open the loop if the points work go out further on the loop if still missing move back toward the panel and open the loop.
