Firefighters' emergency microphone

Wall-mounted emergency microphone, dedicated to firefighters, identical in operation to the 80MF0100123 microphone base: it can be directly connected to the central unit via an 8-conductor (4-pair) fire-resistant J-type cable. Up to four microphone bases can be daisy-chained (on the same line) (interlocked with each other). In this case, the first microphone base on the line is powered directly by the central unit, while the second, third, and fourth require external 24 Vdc@500 mA power supplies. The total length (considering the sum of all cables) must not exceed 800 m. Compared to the 80MF0100123 base, it has the following differences: - the microphone base is protected inside a metal box

• (RAL 3000 red) with glass and wall-mounted
• (instead of a microphone capsule on a flexible gooseneck).
