The NFM-200 A digital fire brigade microphone station is a certified operator unit designed according to DIN 14664 for direct voice communication during fire emergencies. Fully compliant with EN 54-16, VDE 0833-4, and VDE 0828 / EN 50849, this unit can be surface-mounted or integrated into standard fire department information systems (FIZ, FIBS, FKT), making it ideal for fire control panels in public or commercial buildings.

In the event of an emergency, the unit enables both live announcements via a noise-suppressing handheld microphone and activation of pre-recorded evacuation or warning messages. The intuitive user interface includes five clearly labeled buttons for key functions like Automatic Off," "Warning," "Evacuate," and "Speak, supported by five status LEDs that indicate system status and alarm conditions.

Featuring integrated microphone monitoring, redundant RJ-45 networking, and Master-Slave communication for up to 16 devices per controller, the NFM-200 A ensures both compliance and operational reliability. It is delivered in a fire-red wall-mount housing with a lockable door and pre-fitted for a profile half-cylinder lock according to DIN 18252.
