power failure monitoring at tower site

[speedway_navigator]

What do you guys use to let you know shore power went away?

I got a call yesterday from our county radio tech after he went to a site and found our tornado warning siren system and 2 other repeaters were down.
He called the Motorola comm shop to see if they knew, their tech texted some photos of the last time he was there and I was in one so I got the call.

I offered to autograph the photo but for some reason Cameron turned me down, millennials have little respect for us old folks.

I got on the FCC's ASR site after finding out my bookmark was bad and got with Crown castle.
The NOC (if there were 2 next to each other the "what knockers!" line from Young Frankenstein would be appropriate)
guy called back a few minutes later and said the electric meter is in our county's name, even gave me the meter number from a photo they have on file.

Since it looks like this is self inflicted I'd like to give our building manager a way to monitor for all critical sites.

We monitor the automatic transfer switches via Modbus. Voltage and current for both legs of the commercial power service are ATS Modbus registers reported to the network management system.

A Zabbix NMS monitors & logs all the Modbus data and sends alerts when anything is abnormal.

My -48volt and inverter systems monitor for me and will alert us. It can do that by sending an e-mail to our group, and it'll trigger an alarm input on our PBX for those sites.

I've been using DPS Telecom site monitoring equipment to give me room temperature and a sensor that lets me know if there's water on the floor. I have a few sites without suitable DC power plants, and I use an external module to monitor AC power and feed that into the DPS Telelcom box.

i second the DPS tempdefender line, we use them at a lot of fiber huts. nice units, easy to set up and monitor plenty of analog and digital inputs as well as give you actual room temp. they have a built in sensor and a separate plug in one so you can put it in a second area to get a more accurate read.

We monitor the automatic transfer switches via Modbus.

Modbus is a good system but I have found less and less people who know the program. About 8 years ago, on my new installations switched to SNMP which is part of the TCP/IP architecture. Get great cooperation out of the I-T people because it is part of their world. Besides all legs of the power, monitor the generator, door entry, smoke, hazard lights, water on floor even the gas level in the propane tank. Difference with SNMP and Modbus is you need an internet circuit to the site. All of my new sites have at least a microwave connection and many have fiber.

I've used some of the Asentria products, and they've been good. Never really put the site monitoring functions to full use, though.

I've put in some Davicom DV200 panels in at muni radio sites, and helped with some other sites. Good stuff, nice, flexible and powerful.
