Get the simple no flow alarm working first.
The rest is just flim flam which can be implemented with a range of KrisDel special flimflam relays.
Why is it that people who want alarm systems usually insist on an audible alarm and then immediately want a way to shut it off?
They don't want a simple switch in case someone messes with it, so they add an ever increasing list of half ar$sed ideas to make it 'fool proof' more complicated and less reliable. They rarely never actually come up with a written spec' for what they want but will find fault in anything you produce.

A cardboard box lined with foam and painted bright red can be put over the alarm until the problem is fixed. This will act as both 'alarm mute' function and 'alarm mute active' indictor. It is cheap, simple and easy to wire.
KrisDel sell a suitable 'Manual Alarm Mute System' in a variety of colours at $300 each, these come with a certifimicate of authenicity and are tested for audio muting perfomance by being placed over a squirrel which is then poke with a stick.

I don't have a convenient way to draw schematics, but here is a description:

Hot to NO alarm contact to point A to NO silence PB to point B to relay R coil to Neutral.
Point A to NO relay R contact to point B.
Point A to NC relay R contact to horn to Neutral.

Sounds like a simple software problem....I'd suggest that while the squealer is 'choked', that you allow it to emit a periodic 'blat' at some interval to declare that it is disabled, and then a 'woohoo!' when it auto resets. Micro controllers to do this used to be expensive, today they are < $40 US at your local Radio Shack or online. These include 'stamp' devices programmed in basic, Arduino devices programmed in 'c', or the 'propeller' multiprocessor programmed in 'forth'. In any case the device should require less than 2 hours to implement.

The diagrams are part of a modification to add an alarm to a gas turbine generator (PLC) control in ladder relay format. Each alarm has an initiating logic relay, like 0100-05, rung 256: a silencing relay, like 0101-05 rung 247 [in which the "Accept Alarm" relay is slave to the Accept N/C push-button] and an output relay, like 0053-12 rung 256, which has a contact in the common audible alarm/pager call-out rung (not shown). The AlmA54 coil in rung 246 is status change logged (with time) in an alarm logging text file. Sorry about the dislocated relay numbers in rung 247, getting things into CR4 is not always straightforward.

Apologies, should have written "Accept N/O pushbutton"

It's good that there is a <...We...>.

Write down a concise statement of how this thing is intended to operate. This is called the Control Philosophy.

Then get the Programmer/Technician to write down how the equipment will be configured to do this task based upon the above. This is called the Functional Design Specification.

Once those have been discussed and agreed, sanction the Programmer/Technician to do it according to the above, test it, and report back on a record sheet of some sort. This is called Commissioning.
