PL 70EN CEILING SPEAKER FIRE DOME DESCRIPTION The PL 70 EN is a ceiling speaker featuring a flameproof steel bottom designed for recess installation in false ceilings or panels. It is especially suitable for broadcasting alarm messages thanks to highly intelligible sound reproduction and is resistant to the high temperatures reached during fires. The terminal connection boards are in ceramic material for input and output flameproof cables. A thermal fuse, protects the integrity of the line in case of heat affecting the speaker. Ground screw. Cables inside speaker made using flameproof leads.

Before in stalling the loudspeaker, make sure there is sufficient space behind the false ceiling panel to hold the speaker: with respect to the support surface of the front flange of the loudspeaker, a free space 150 mm (c. 6”) deep is necessary. In outdoor use, avoid in stalling the loudspeaker in places exposed to harsh weather conditions. www.rcf.it RCF products are continually improved.
