Would help if we new what the alarm was for! Fire , Flood, Gas, Low voltage, High voltage, Temperature, High or Low, Humidity or what??
I am sorry but that question and picture tell us nothing, unless of course one happens to be au fait with that particular panel.

Thanks for replying, the problem is I don’t know what the alarm actually is for. I do know it activates when I manually operate the bilge pumps, but it continues to sound even when I’ve isolated all three so was wondering if maybe it also sounds when something else triggers it.Would help if we new what the alarm was for!

I have no wiring diagram so a bit stumped.
Have called an electrician to take a look next week.

Check for a relay that may have stuck points

Good tip thanks.

The alarm sometimes has a separate float switch to activate .

OK I would, from that reply, assume that it is a bilge pump alarm, to indicate pump(s) running. As stated could be a relay in the pump circuit. I would have thought it unlikely to be a separate float as it operates when you manually operate Any of the pumps? I would try tracing the wiring and see if you can find a relay or possibly a box with more than one (one relay/pump) I would have thought around the panel area.
If not then OK over to the electrician. Good luck!

Thanks, the bilge pumps have individual trips which isolate them, each has a little light which indicates it has power to it. When I turn off the trips the lights go out so definitely no power to them.

Are you sure that is the alarm and not just the auto switch for the pump(s) Are all the pumps in the same bilge or in different locations? If in separate bilges then you will most likely have more than one of these. I would expect from what you have said that the alarm will be wired through relay(s) driven by the power line to the pump. I would have to see on site to be more specific.

Thanks for input Alex, the three pumps are all in different locations, I’m hoping the electrician can trace it down next week.

There must be 3 switches then

On reflection it could be that the pumps have an integrated auto switch and a level switch(s) is used for the alarm but it would have to have water to that level to operate in auto and also be wired such that it is bypassed in manual. There could be three and one faulty . I am afraid that without seeing exactly what what your set up is, I am as stated previously stabbing in the dark somewhat.
Something I should have asked in the beginning
Do any of the pumps run when switched to auto with a dry bilge?? Would be a good indication of a faulty float.

That's not an alarm switch, it's a water level sensor. If the water level exceeds the "run level" it completes a circuit and the pump operates.
Typically, the alarm if wired to the same sensor, so if the pump is running the alarm sounds. When your alarm goes off, is one of the pumps running ? If so, you likely have a faulty sensor. Sometimes the sensors get dirty and need cleaning.
If there is only one alarm buzzer for 3 pumps it's likely wired via diodes to each bilge sensor.
