The Grade 3 Deltabell X has the same engineer friendly features as the popular Deltabell, but has the enhancement of twin piezo sounders with each piezo offering an audio output of 108 dB.
When coupled with the Deltabell X Lightbox, which fully illuminates the front of the bellbox, the visual security of the property is maximised, complimenting the enhanced audible deterrent of the twin piezo sounders.
The Deltabell X weather proof siren has been designed in the UK for use in EN50131-1 Systems that meet Security Grade 3 and Environmental Class IV requirements.
