It's a minor thing .. but worth "knowing" ... the power sounder is part of the "Thatcham" designation of the alarm system.
If you simply remove it, and don't replace it, theoretically you cannot declare that it has a "factory fit" alarm system to your Insurance company.
If you have already declared that, then, legally, you should tell them you have disabled that aspect.
Should the vehicle be subject to an insurance claim, it is "possible" that the claim could be denied if they found out you had disabled it and not told them - they could, legitimately, accuse you of not telling them of a significant change to the vehicle specification.
It is argued, by some, that the chance of the Insurers finding out is pretty slim, personally, for the sake of £40 (ish) I purchased and fitted a brand new replacement power sounder. Now that was a few years back and I have no idea of the current price.
Your car, your choice, but worth a few seconds thought before deciding which way to go, IMHO ..
