[Hai-users] AC Power Off Detection

[Doug Ringler]

Dan,

Yes, fixed with a simple relay tagged to a new zone on the panel.  The issue was to detect the momentary loss of AC to the panel until the generator kicks in.  I used to use the loss of AC to the panel in the OmniPro (which was instaneous), then after about 4 seconds or so, the detection of AC to the panel from the generator (with a line in the programming detecting loss of AC elsewhere in the house not tagged to the generator) as an output and zone to alarm notification that the generator was on.  Anyways, as you say, simple fix with a relay.

Another issue:  The stand-by generator causes fluttering of lights controlled by HAI dimmers on UPB.  Other lights don't flicker.  I think the issue is the generator has some variability in the 60Hz range...so when I measure it, it can range from 60.5 to 59.6Hz while the power from the street is 60Hz right on the mark.  Guess I could fix with a whole house UPS that has tight Hz control.........Anyone else know of any easy fixes?

Thanks.

Doug

  Dunno why you would need a solenoid.  How about a cheap wall wart power supply.   Put the output onto one of the inputs.  Sorry, I don't remember the voltages required/allowed but they should be in the specs.  A small DC power supply should work fine I think.  If not, then a cheap relay attached to one would do it.

  Clarification:  The Detection of AC Power Off for the log command to work still requires the AC Power to be off for at least 10 or 15 sec.  Is there a way to detect momentary AC Power Off without the delay?

   

  Thanks!

    Running OmniProII ver 3.0 in this location.  I realize that for the communicator and log, the AC loss must be for at least 3 min.  But, in some lines of programming, I need to detect ACPower Off for any momentary amount.  However, testing it with:  When AC Power Off, then Log Power Out---will not work.  Am I missing something?  I could run a solenoid for this, but would rather not.

     

    Thanks
