KSB5516 replacement. Tamper?

[Liverpool-Lad]

Hi folks. Does anyone know if the internal sounder has a tamper on it if I try and replace it? Makes an electrical humming noise now and again. The keypad is also a bit ropey so don't fancy trying to input the code whilst that is on!

I should add the alarm is a late 90s c&k securitech job with the metal control box in the box room cupboard upstairs

Many thanks

KSB5516MS does and KSB5516 doesn’t have the tamper.

a Video including the humming may be useful if the keypad is ropey then maybe get a replacement?

Thanks for the advice. I think the keypad (c&k) is obsolete so I may have a job in finding one. I'll post a video up of tbe humming noise

Is it the speaker or transformer buzzing in the metal box ?

Buzzing transformer could have faulty battery.

Speaker in the hall. Sometimes it's quiet but more often than not now it's constant. The metal box is all quiet. Added a video. Thanks
