PL 68EN
CEILING SPEAKER WITH FIRE DOME
DESCRIPTION
PL 68EN is a ceiling speaker featuring a
flameproof steel back can, designed for
recess installation into ceilings or panels. It is
especially suitable for broadcasting alarm
messages thanks to the highly intelligible
sound reproduction and its resistance to high
temperatures reached during fires. The
terminal connection blocks, for input and
output flameproof cables, are made of
ceramic material. A thermal fuse protects the
integrity of the line in case of heat affecting
the speaker. Ground screw available (if
needed). Cables inside speaker made using
flameproof leads.
FEATURES

NOTES
NO CAUTION is NECESSARY in case of ALERTED PERSON for AUDIO voltages up to 120V, when warning symbols are present near the connection
terminals. In the case of AUDIO voltages up to 71V, it is not even necessary to put warning symbols.
No need of linking to earth metal parts of speakers equipped with transformers and connected to 70.7 V / 100 V outputs of power amplifiers that do
not have any reference to earth (ref. EN 62368-1 item 4.3.2.2 ), unless specific local requirements.
