You should also check out MAC+ or Mini-MAC+ - made by a company
called Comlab.  (www.comlab.com)  I would say they are state of the
art.  I'm familiar with both Comlab and Protek, and for my money
Comlab has the edge right now.  Depending on the size of your
system/requirements, multiple digital & analog inputs, and relay
outputs, and probably even more that I'm not familiar with.

True:  Have actually had instances of a Protek on a system; power
amplifier starts to go soft, and pages me out.  Before the end users
can notice a problem in coverage, I'm on the phone to alert customer
contact what's going on & that I'm on my way to take care of it
before they go completely down.

It's very impressive, but you do want to be careful what you're
monitoring, and how you set your trip-points, and be esp. careful of
'false positives' - alerts that come to you when there's nothing
really wrong; it can be easy to get complacent if you don't
investigate WHY you're getting alerts that are wrong.  Granted,
that's better than NOT monitoring something that IS important!

I'm by no means an expert on their applications, but I am sold on
their use, especially in a critical system.
