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 backlit sounder produces a loud siren and strobe to alert neighbours of any intrusion into your property.
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. Clear plastic covers and base allow additional light to shine through, whilst the white cover variant provides even more visibility.
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.
