Deter & scare intruders with an external siren/sounder
Use the power of sound to protect your home
Deltabell wired & wireless external sirens & bell boxes system
An externally-mounted siren is one of the most obvious features of a Pyronix home alarm system installed by Ultimate Alarms. We offer both wired & wireless versions of the high security Deltabell sounders. The bell box fitted outside acts as a visual deterrent to thieves while the flashing light & loud noise when activated attract immediate attention in the event of a break-in & persuade any burglar to leave quickly.

Deltabell Exterior Alarm Bell Features
High-Performance Audible Alarm
High performance Piezo with low power delivers a loud audible alarm, ensuring alarm activations are heard and responded to.
An all-day, all-night deterrent
The siren has a backlit sounder with an illuminated cover that is activated at night as a visual deterrent, with a choice of five colours for bases and covers.
Visual & audible alarm combined
The backlit sounder emits a loud siren and a strobe to alert your neighbours and passers-by of any attempted break-in.
Tamper-proof
The bell box has a tamper-proof design, so if the cover, base or power supply are interfered with, the alarm will be triggered.
Weather-proof
The illuminated sounder is made with waterproof polycarbonate plastic and has extra protection around its electronics for trouble-free operation no matter what the weather.
Battery back-up
The Deltabell comes with a built-in backup battery to ensure that the siren will still flash & sound when triggered even in the event of a power cut or interference with the supply.
