High-Decibel External Alarm Siren with Bright Strobe Light
The Ness Slim Line External Combination Siren and Strobe delivers powerful 115dB alarm output combined with a high-visibility strobe light for maximum deterrent effect. This weatherproof unit provides both audible and visual alerts when your alarm system is triggered, ensuring intruders know they've been detected while alerting neighbours and passersby to potential security threats.
Why Choose a Combination Siren & Strobe?

The loud 115dB siren can be heard from significant distances, while the bright strobe light provides visual confirmation of an alarm activation - especially valuable at night or in noisy environments.

The weatherproof design ensures reliable operation through rain, heat, and dust.
