I have just drawn the short straw at work .... oh yay.

So, we need to monitor a range of things, -80°C freezers, +37°C rooms, freeze driers, water cooling systems, light levels,  and so on.

We would (should?) like to monitor power to various parts of the building too, and I figure we may look at flood alarms, and other bits of scientific equipment

that have alarm outputs, or various analog (0-1v, 0-10v, 4-20mA, etc) outputs.

We would like to set up intelligent alarm systems, so only the required people for each situation need be called out. We are talking about perhaps 80 different people.

We would like user monitoring of their equipment, eg the last hour, day, week temperature measurements of a -80C freezer, potentially 300+ people of varying technical ability

It should be able to call landlines, cellphones, send txts and emails as alarms or as say daily/weekly reports 

If users are heading overseas (happens a lot) then we would like them to be able to self manage their status as being away (no need to call people in Germany....etc)

We would like a more limited set of users to be able to change the alarm settings for their equipment, ie this week an incubator needs to be @37C, next week 10°C

If possible each alarm point should be monitored over ethernet (with POE to power the sensor/alarm) Our network switches all have UPS's on them so batteries are not required

I have ZERO experience with building management systems or this level of environmental systems management.

Where do I start to go down this rabbit hole, I am sure someone can sell us a needlessly complex system that would be fine in an industrial setting

but much of the management of this is likely to fall on administrative staff . And as always, as soon as you get something up and running there will be all sorts of requests

for monitoring (oxygen, liquid nitrogen, water flow, opening times of doors, etc etc).

Any help about where to start will be greatly appreciated (I am a registered sparkie , but I service scientific equipment these days and do some IT support, etc)
