The WSB1020 wireless sounder-beacon combines audible and visual signaling in a single device, featuring its own address for independent control by the panel. Compatible with EWT100 addressable translators and XWT100 expansions, it offers 32 selectable tones via DIP switches and supports differentiated activation for pre-alarm and alarm. The integrated flasher enhances alarm effectiveness, making it ideal for noisy environments or areas with hearing-impaired occupants. It can also be installed as a standalone sounder for ceiling mounting using the optional cap (available in white or red). It features two-way communication over dual redundant radio channels, ensuring a range of up to 200 meters. Powered by long-life lithium batteries, it guarantees up to 5 years of autonomy while keeping operating costs low.
