14 LBC1256/00 EVAC
Connection Adapter
14.1 Introduction
Using an LBC1256/00 EVAC Connection Adapter,
loudspeakers that do not contain a ceramic block with a
thermal fuse can be upgraded to comply to evacuation
standards.
14.2 Installation
The EVAC connection adapter must be installed in an
enclosure with double-sided tape (see figure 14.1). The
cable between the loudspeaker and the EVAC
connection block must be short to make sure that the
temperature of the thermal fuse does not differ from the
temperature of the cable. Otherwise, the thermal fuse
will not blow before there is a short-circuit in the
loudspeaker line.

connector to which the loudspeaker can be connected
(see figure 14.2).
