Around-the-clock deterrent

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.

Combined audible and visual alarm

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