The Deltabell Plus features a fully backlit sounder with illuminated cover which is activated at night to provide an around-the-clock visual deterrent, with a choice of colours for both bases and covers.

Audible and visual deterrent

The Deltabell Plus backlit sounder produces a loud siren and strobe to alert neighbours to any intrusion on your property.

Tamper protection

The Deltabell Plus' tamper proof design means that if the cover, base or power are altered the alarm will be triggered.

Enhanced weather protection

Made with waterproof polycarbonate plastics, the Deltabell Plus illuminated sounder has extra protection around the electronics for excellent performance whatever the weather.

Protected day and night

The patented backlit design allows your security sounder to be visible day and night. The base is made with clear plastic which also allows additional light to shine through, as are the covers and, particularly the white, also allow additional light to glow through the front for even more visibility. 


Technical Features

With a number of engineer friendly features, the Deltabell Plus illuminated sounder is the perfect choice. The unique levelling mechanism and modular components now make simple sounder installation a reality for you.

Easy to install

With a built in spirit level and guide holes, the Deltabell Plus external sounder is quick and easy to install.

Engineer hold off

When you are in the Engineers Menu the illuminated sounder automatically disables so that you can work on it without the fear of triggering the alarm.
