I have used the APC Environmental Manager (EMU) to do this. In our case we ran a 4-pair line from the generator to the EMU. One pair was connected to the EMU so that we could monitor and alert on the run-cycles of the generator. Our transfer switch did not have these capabilities, but you could apply the same configuration we used for out generator. The EMU has built-in alerting as well as the ability to send SNMP traps. - Chris On Fri, May 14, 2010 at 1:59 PM, Tom Beecher <tbeecher@localnet.com> wrote:
I'm presently doing some research into a SNMP-enabled device to monitor a set of aux contacts on our transfer switch in order to be able to monitor it's status (on generator or on commercial) from our monitoring platform. I've seen a few interesting devices out there that can accomplish this, however I thought I'd query the list to see if anyone has thoughts about a particular unit they've worked with.
Thanks in advance,
