The Bosch LB1-UM06E-1 is a surface mounted circular metal cabinet loudspeaker for emergency paging, compliant with EN 54-24 as well as BS5839 P8 and EN60849 for use in voice evacuation sound systems. It can also be partially recessed into a wall.

Rated at 6 watts and suitable for 70 / 100 volt line sound systems only. Vandal resistant and ideal for places such as shopping centres, schools, car parks and offices.

The LB1UM06E-1 is suitable for emergency paging in voice alarm systems, and has built-in protection to ensure that, in the event of a fire, damage to the loudspeaker does not result in failure of the circuit to which it is connected. This maintains the system integrity so that loudspeakers in other areas can still be used to inform people of the situation. Also compliant with British Standard BS5839 part 8 and EN 60849.
