[SBE] Burk Arc 16 Alarms

[Dennis Sloatman]

Here's one possible solution I have used which provides "granular control"
of alarm reporting:

 

Connect one raise or lower channel to an unused status input.  Set this
status to alarm without delay.  Turn off the alarm on the generator status
input.  Write a simple autopilot (I can help with this if you desire) that
constantly monitors the generator status.

 

The Auto pilot can gave a built-in "Glitch delay" to prevent random and
unnecessary callouts. The autopilot will then continue to call by triggering
the alarm until the generator is off-line.  It would be possible to use
another raise or lower channel to stop the autopilot (as an
"acknowledgement") as well.

 

I've used this method in the past for a variety of similar alarms, such as
tower light outages, etc.

The TPO is 5. My main concern is the total draw of the contactor coils
during switching.

The system has remote for choosing transmitters and Day or Nite. It does not
have remote for choosing DA/NDA.
