CEILING SPEAKER FIRE DOME
The PL 60FD ceiling speaker can insulate
itself from the line in case of fire. Thanks to its
ceramic termination blocks (capable of
withstanding temperatures in excess of 650°
C/202 °F), its thermal fuse ( threshold: 150
°C/ 302 °F) and its fire-resistant cable, the
speaker does not allow fire to move to the
audio system. It is ideal for the reproduction
of announcements and background music
and features a 4 position manual switch) to
select the speaker power.
• Expecially suitable for alarm/evac applications
