Hello,
I am looking into a Deltabell X and i am a little confused.
Could somebody please confirm whether the deltabell X twin piezo is 104 or a 109 dbA external sounder? On cctvcentral it is rated as 104 dbA.
My second question is, what is the difference between the deltabell X grade 2 and grade 3?
Thanks
