    Yes I do the system is older and does not have very good information to view to troubleshoot it very easily. I was just wondering if anybody has worked on this model and is very familiar with it.

    Does the unit have the microtech 200 or the unt 33 (johnson)?
    Mt 200 would have alarm history
    Unt 33 only alarm light

    No it does not have any control devices on the system at all so I cannot look up any alarm history on it.

    Then it has the unt controller. That will require pulling the wiring diagram and troubleshooting.
