[Hai-users] AC Power Off Detection

[Dan Barclay]

Ah.  I had a relay put in on the *power company* side of my throwover
switch.  I've got a 400 amp feed and I prefer to manually move it over and
bring it back.  In storms, when there is physical damage to the house, I
didn't want power coming on without permission.  I live on the Gulf Coast
and have had trees through the roof.

 

I can live with the power being out a while, or with trees through the roof.
I've had a fire before and one is quite enough, thanks! <g>

 

That brings on the problem of not knowing when the power is back on!   So, a
relay (and light) on that feed did the trick.

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
