Bosch LC1-MFD Metal Fire Dome with Ceramic Connector for LC1

The LC1-MFD is the metal fire dome for Bosch LC1 ceiling loudspeakers, fitted with a ceramic terminal connector that survives temperatures which would destroy a plastic block. It is EN 54-24 certified as part of the LC1 range.

The connector carries a loop-through facility, so one dome passes the 70 V or 100 V line on to the next loudspeaker in the zone without a separate junction box. The steel shell is red, weighs 1,000 g, and works from -25 to 55 °C.
