Are these usually installed/furnished by electrical? THanks.

In my experience they are mostly supplied/installed by the sprinkler contractor.
The tamper switch can be installed by just about anyone from the fire alarm tech, sprinkler guy or electrician. The water flow switch will involve cutting into the sprinkler pipe and I would leave that up to the sprinkler guy.
just another side note, working on waterflow devices usually requires you carry liability insurance that covers waterflow work
No more well pump connections, or lift pump connections, without looking at my insurance. Am I liable for a tripped GFCI that makes a lift pump fail?:rant:

They're installed as part of the sprinkler system. It's up to you to get power to them.
A side note: the switches typically have a built-in delay, and require water to run for almost a minute before they trip.
Power or a fire alarm circuit??
What do well pumps and lift pumps have to do with fire waterflow devices?I thhought the subject was fire alarm systems
I know what the subject is but isn't a pressure switch or float switch for mentioned equipment a "water flow" device?
Might not be as funny as it sounds, insurance will find any technicality they can to get out of paying a claim, that is just what they do.
Power or fire alarm circuit?
Might have both - a set of contacts for the alarm system, and a set of contacts that supplies power to an alarm bell / gong.
Many times it's an 'either/or' situation ... a gong is required if there is no monitored alarm system. A similar situation arises with kitchen hoods.
Yes, there can be power on some fire circuits, here is a good link that explains more about fire water flow. http://www.firealarmsonline.com/2011/08/water-flow-backflow-osy-tamper-switch.html

I was somewhat discouraged to find mistakes in the article. One example: OS&Y valves are not the same as backflow preventers. The fact that they are present on most backflow preventers does not make them the same thing. Good luck with that kind of thinking going to the NICET test.
