Protection
The loudspeakers have built-in protection to ensure
that fire damage to the loudspeakers does not cause
failure of the connected circuit. In this way system
integrity is maintained, ensuring loudspeakers in other
areas can still be used to inform people of the
situation.
The loudspeakers can also be used in combination
with a metal fire-dome to increase protection of the
cable termination.
