BOSCH FNM-420-A-RD Internal Siren
Product Code: FNM-420-A-RD
Bosch FNM-420-A-RD internal siren is used independently to provide alarm signal directly at the fire location. It offers 32 alarm types and DIN 33404 evacuation tone for different requirements. The provision of warning at the point where the event occurs is a critical detail that accelerates evacuation in enclosed spaces where the central siren in the corridor may not be heard.
