|In order to provide the highest level of personal protection and security in the home and in the office or company, BRAHMS has developed a series of sirens for external installation, each offering the maximum reliability and efficiency. The sirens in the BRAHMS range are audible at a considerable distance and fitted with warning lights to identify the source of the alarm, and all models are in full compliance with CEI standard 79-2, level 2. Built in weatherproof white methacrylate and resistant to tampering and vandalism, these sirens are fully protected against removal and aperture; they are independently powered, and will sound even if the power supply to the control module is disconnected (whether purposely or due to a power outage). The sirens also feature anti-tampering devices, anti-removal devices and a system for protection against reversal of the battery poles. All the sirens in this new range are easy to install thanks to an intuitive system of connections and automatic addressing via a self-learning system.
