Fire brigades & rescue services

Since the 1970s, we deliver single sirens or siren groups to European fire brigades and rescue services, Hardware and software included. According to customer requirements and specifications we adjust the siren to external conditions such as the site geology, climate and environmental noise. We consider building density (rural area, residential area or cities) and calculate the required sound propagation. Especially for local authorities and fire brigades we recommend the replacement of old E57 motor sirens with cost-efficient electronic sirens.

Other application possibilities

Our modern, electronic sirens are applicable in many ways. They can be used not only for alerting but for communication purposes as well, due to their equipment with live voice and memory voice option. For this reason, our electronic sirens can be found even at golf course areas.
